    This is a dispute about the timing of a school district’s
    provision of special education and related services to a child
    with autism. Although the school district provided those
    services to the child after he was diagnosed with autism in
    April 2017, it had denied the child those services fourteen
    months earlier. At that time, in February 2016, the child was
    six years old and in first grade, and the school district
    determined that he was ineligible for those services because he
    was not disabled and did not need them.
    2
    The child’s parents disagreed with that ineligibility
    determination and sought redress under the Individuals with
    Disabilities Education Act (the ‘IDEA’) and § 504 of the
    Rehabilitation Act. In the administrative grievance that they
    filed against the school district, they asserted that the school
    district violated its statutory obligation to identify, locate, and
    evaluate children with disabilities. On the premise that the
    school district did not fulfill that duty, the parents claimed that
    the school district denied their child his statutory right to a free
    appropriate public education (a ‘FAPE’).
    The parents’ claims did not succeed at the administrative
    level or in the District Court. After holding an evidentiary
    hearing, a hearing officer denied the parents’ administrative
    grievance. To dispute that outcome along with the hearing
    officer’s evidentiary rulings, the parents filed a complaint in
    federal court. But the District Court upheld the hearing
    officer’s determination and entered summary judgment in the
    school district’s favor.
    The parents have now appealed the District Court’s ruling.
    Reviewing the District Court’s legal conclusions de novo, its
    factual findings for clear error, and its evidentiary rulings for
    abuse of discretion, see Munir v. Pottsville Area Sch. Dist.,
    
    723 F.3d 423
    , 430 (3d Cir. 2013); Susan N. v. Wilson Sch.
    Dist., 
    70 F.3d 751
    , 760 (3d Cir. 1995), we will affirm the
    judgment for the reasons below.
    I. FACTUAL BACKGROUND
    A. The Four Months Before C.M. Enrolled in First
    Grade in the Summit Public School District
    From his infancy through kindergarten, C.M. attended day
    care full-time. He met his developmental milestones, and the
    day care described his participation and adjustment to
    kindergarten as good and his behavior as fairly typical. But
    toward the end of kindergarten, in May 2015, he began to have
    3
    meltdowns at day care. The day care staff could not manage
    C.M.’s behavior, and they asked his parents to remove him
    from the day care, which his parents did.
    Prompted by concerns over his behavior (but not his
    academic performance), C.M.’s parents retained Dr. Carolyn
    McGuffog,      a     clinical   psychologist and    school
    neuropsychologist, to evaluate C.M. In July and August of
    2015, Dr. McGuffog administered sixteen neuropsychological
    tests to C.M. over the course of four days.
    B. C.M.’s First Month of First Grade in the Summit
    Public School District
    In September 2015, C.M. started first grade in the Summit
    Public School District. Despite Dr. McGuffog’s admonition
    that it was “very, very important to notify the school up front,”
    C.M.’s parents did not alert the school district or his teacher to
    his meltdowns in kindergarten. Hr’g Tr. at 51:1–2 (June 8,
    2018) (testimony of Dr. Carolyn McGuffog) (JA1241).
    Similarly, before the start of school, C.M.’s parents did not
    inform anyone at Summit that they had retained Dr. McGuffog
    to evaluate C.M.
    But even without that upfront notice, by the middle of
    September, Summit’s staff recognized that C.M. was
    displaying behavioral problems in class. He got angry quickly,
    and in frustration he would shout, push desks and staff, throw
    materials, leave the room, hide under his desk, or refuse to talk.
    He was removed from the classroom twice for disruptive
    behavior, but after speaking with the school psychologist, he
    calmed down and was able to return to the classroom and
    participate. After one of those incidents, Summit’s staff
    contacted C.M.’s parents and learned for the first time about
    his behavioral issues at the end of kindergarten.
    By the end of C.M.’s first month of first grade, Summit had
    assembled a multidisciplinary team to examine potential
    4
    interventions in the classroom. That team consisted of the
    school principal, the school psychologist, a special-education
    teacher, a basic-skills teacher (who provides general-education
    supplemental instruction), and C.M.’s general-education
    teacher. They met in late September to identify and implement
    the least restrictive classroom interventions that would
    stabilize C.M.’s behavior.
    After developing an intervention plan, the team
    implemented several interventions. Those included having
    places in the classroom for C.M. to go when he became upset,
    having C.M. participate in a lunch-time social-skills group
    once a week, and placing a card on C.M.’s desk to remind him
    of certain rules, such as to use kind words and to avoid hurting
    his friends. The intervention plan also called for rewarding
    C.M. with Pokémon cards for following those rules. In
    addition to those behavioral interventions, the team
    implemented interventions to assist C.M. academically. The
    team realized that C.M. had begun to experience academic
    difficulties, and it arranged for him to receive extra reading
    lessons four days a week and participate in an after-school
    basic-skills program twice a week.
    Finally, the intervention team established a plan for
    monitoring the effects of these interventions, and it scheduled
    a second meeting for November 18 to assess the effects of the
    interventions.
    C. The Results of the McGuffog Report and the
    Broadening Evaluation of C.M.
    In early October, Dr. McGuffog completed a forty-eight-
    page report on her evaluations and shared it with C.M.’s
    parents. That report provided a detailed analysis of C.M.’s test
    results, and they were quite mixed. In several areas, C.M.
    demonstrated cognitive strength and normal development,
    such as a very high nonverbal intelligence, advanced
    mathematical skills, an average working memory, and average
    5
    reading scores. But the test results also revealed areas of
    concern. C.M. had a notable weakness in inhibitory control,
    and although he barely met the minimum age requirement for
    one of the tests, it showed that he had significant problems with
    attentional regulation and impulsivity. The variation in the test
    results led Dr. McGuffog to observe that C.M. “presents with
    a complex array of neurocognitive strengths and weaknesses
    that poses a challenging diagnostic challenge, particularly
    given his young age.”           McGuffog Neuropsychological
    Evaluation Report at 36 (Oct. 8, 2015) (JA1720).
    Despite the challenges, Dr. McGuffog made certain
    diagnoses. She determined that C.M. had three disorders: a
    language disorder, a social (pragmatic) communication
    disorder, and a specific learning disorder. She further
    recognized that C.M.’s test results were suggestive of autism
    and ADHD, but due to the combination of C.M.’s strengths,
    weaknesses, and young age, Dr. McGuffog declined to
    diagnose him with autism or ADHD. Instead, she issued ‘rule-
    out diagnoses’ for autism and ADHD, meaning that while she
    did not diagnose those conditions, she could not rule them out
    either.
    Dr. McGuffog also made several recommendations for
    Summit with respect to C.M.’s schooling. She suggested that
    C.M. receive instruction in social skills, especially by means
    of a social-skills group. She encouraged Summit to implement
    behavioral supports and to provide academic support in
    language arts. She also recommended that C.M. undergo two
    more evaluations – one for speech and language, the other for
    occupational therapy.
    Even before it received those recommendations, Summit’s
    intervention team had begun – on its own – to implement many
    of those interventions, such as the use of a social-skills group
    and a number of behavioral supports. And by early February
    2016, Summit had implemented all of Dr. McGuffog’s
    recommendations for C.M.’s schooling.
    6
    Dr. McGuffog also made recommendations for C.M.’s
    parents. Based on those recommendations, they retained an
    occupational therapist and a psychologist to evaluate C.M. and
    prepare reports on their findings. Also, on Dr. McGuffog’s
    advice, the parents scheduled weekly appointments for C.M.
    with an occupational therapist and a psychologist.
    D. C.M.’s Parents Request that Summit Evaluate
    C.M. for Special Education
    Although not recommended in the McGuffog Report,
    C.M.’s parents requested, on October 26, 2015, that Summit
    evaluate C.M. for special education and related services. In
    response, Summit assembled a multidisciplinary group of nine
    staff members and other professionals to formulate a plan for
    evaluating C.M. 1 And in a meeting with C.M.’s parents and
    Dr. McGuffog on November 11, that group offered to use every
    procedure at its disposal to evaluate C.M.
    After that meeting, Summit formulated a proposal that
    included five evaluations of C.M. in different areas. Summit
    proposed a speech-and-language evaluation, a physical therapy
    assessment, a social assessment, a psychological evaluation,
    and an occupational therapy functional assessment. Summit
    further proposed that each of those evaluations be conducted
    by an appropriately qualified person: a speech-language
    specialist, a physical therapist, a social worker, a psychologist,
    and an occupational therapist. C.M.’s parents consented to that
    plan.
    1
    The group included a learning consultant, a psychologist, a
    social worker, a speech-language specialist, an occupational
    therapist, the principal, C.M.’s teacher, and two graduate-level
    psychology interns.
    7
    E. Summit’s Review of Its Initial Interventions
    While the five evaluations were getting underway, the
    intervention team met on November 18 to review the
    previously implemented interventions. The team concluded
    that C.M. was making progress and that the interventions were
    working. The incentive to earn Pokémon cards daily had
    reduced C.M.’s outbursts to two for the entire month-and-a-
    half period. In addition to his behavioral growth, C.M. was
    making clear progress with his social skills. The intervention
    team also learned that C.M.’s teacher had, in line with Dr.
    McGuffog’s recommendations, implemented some additional
    sensory interventions, such as Velcro under his desk, to help
    him sit still and pay attention. The team found that C.M. used
    those interventions and seemed to like them. C.M. also
    improved academically in fifteen areas, such as his reading
    level, his use of writing conventions, and his mathematical
    algebraic thinking.
    Because C.M. had made meaningful progress and the
    interventions were successful, the intervention team decided to
    continue all of them. As far as making another assessment of
    C.M.’s progress, the team decided to hold another meeting
    after the five evaluations were completed.
    F. Summit’s Determination, on February 8, 2016, that
    C.M. Was Ineligible for Special Education
    By early February 2016, Summit had amassed an array of
    data on whether C.M. was eligible for special education. It had
    the materials provided by C.M.’s parents: the McGuffog
    Report, as well as supplemental reports from C.M.’s
    occupational therapist and psychologist. The occupational
    therapist determined that C.M. had delays in gross motor and
    fine motor skills and that he had difficulty in coordination and
    self-regulating. The psychologist, after observing C.M. in the
    classroom, reported that he was participating independently,
    and although his attention wandered, it was restored with
    8
    prompts. Overall, the psychologist found that C.M. was not
    disruptive and that he could answer his teacher’s questions.
    Summit also had the results of the five evaluations that it
    performed specifically to evaluate C.M. for special education.
    The assessment of C.M.’s speech and language abilities
    involved two tests administered by a certified and licensed
    speech-language pathologist. 2 C.M. scored in the 50th and
    17th percentile on those. But to be communication impaired,
    a child must score in the tenth percentile or below on two
    assessments – and C.M. was not in that range on either test.
    The results of the physical therapy evaluation, performed
    by a physical therapist, reported areas of weakness. Those
    included decreased attention as well as proximal shoulder and
    hip joint weakness. But those issues did not affect C.M.’s gross
    motor function during his school-day routine.
    The social assessment, performed by a licensed social
    worker, did not report any social concerns in the classroom.
    The assessment found that C.M. got along well with his peers,
    having made two friendships, and that he was very gentle,
    sweet, and kind to other students, except when he felt that he
    or someone else was the victim of an injustice (which was
    infrequent). The social worker also observed that C.M. would
    fidget and could get off task, but that was easily remedied with
    redirection.
    The psychological evaluation, performed by the school
    psychologist, similarly determined that C.M. was generally
    focused and on task, but that he required occasional adult
    redirection. Like the social assessment, the psychological
    2
    The two tests were the Comprehensive Assessment of Spoken
    Language (‘CASL’) and the Language Processing Test
    Elementary -3 (‘LPT-3’).
    9
    evaluation described C.M. as friendly, cooperative, and
    extremely polite. It also concluded that C.M. had a positive
    attitude toward school, his family, and his peers.
    The final evaluation – an occupational therapy assessment
    performed by a registered occupational therapist – revealed
    that C.M.’s gross motor skills, fine motor skills, and bilateral
    motor skills were in the functional range. The occupational
    therapist further determined that C.M. could perform school-
    related tasks, but that for unfamiliar directions, he needed
    repetition and benefited from one-on-one guidance.
    Summit also gathered data on C.M. from several other
    sources. Those included samples of C.M.’s work, paperwork
    from the intervention team, and comments from C.M.’s parents
    and Dr. McGuffog. In addition, Summit reviewed C.M.’s
    report card, on which his teacher remarked that he had
    developed “a greater understanding of the routines and
    expectations of first grade,” had “made strides with
    organizational skills since the start of the year,” and was
    “practicing patience and self-control.” Pupil Progress Report
    (Grade 1) at 4 (JA1752).
    To evaluate all of that data and assess C.M.’s eligibility for
    special education, Summit designated a group of fourteen staff
    members and other professionals from multiple disciplines. 3
    After considering the compiled data and sharing it with C.M.’s
    parents, the group held a meeting on February 8, 2016, with
    3
    The group consisted of the school psychologist, the school
    social worker, the school principal, the supervisor of special
    education, a learning disabilities teacher consultant, two
    physical therapists, two occupational therapists, C.M.’s
    general-education teacher, C.M.’s basic-skills teacher, an
    expert certified in speech-language pathology, and two
    graduate-level psychology interns.
    10
    C.M.’s parents, Dr. McGuffog, and C.M.’s special-education
    advocate.
    That meeting ended with a determination that C.M. did not
    meet the eligibility requirements for special education and
    related services. All fourteen members of Summit’s evaluation
    team agreed with that conclusion either because C.M. did not
    have a disability or because C.M did not need special education
    and related services. In support of that decision, Summit’s
    team relied on the positive effects of the strategic behavioral
    interventions, which reduced the incidents of poor behavior.
    The group also recognized C.M.’s progress in reading and
    math as well as the behavioral improvements noted on his
    report card. Summit’s staff understood that C.M. still had
    some weaknesses, but because he had positively responded to
    the interventions, they decided to continue to implement those
    in lieu of special education and related services.
    C.M.’s parents, Dr. McGuffog, and C.M.’s special-
    education advocate disagreed with the conclusion that C.M.
    was ineligible for special education. Consistent with that
    belief, C.M.’s parents continued to have their son evaluated by
    Dr. McGuffog. They also retained a speech pathologist, Alana
    Fichtelberg, to conduct additional evaluations of C.M. Both of
    those professionals issued additional reports at the parents’
    request. In early 2017, Dr. McGuffog concluded that C.M.
    should be diagnosed with autism and ADHD.
    After Summit received Dr. McGuffog’s recommendation,
    it referred C.M. to a psychiatrist who diagnosed him with
    autism and ADHD. In April 2017, Summit determined that,
    based on the autism diagnosis, C.M. needed special education
    and related services, and it began developing an individualized
    education program (an ‘IEP’) for him. C.M.’s parents agreed
    to that IEP in August 2017, shortly before C.M. entered third
    grade.
    In July 2019, C.M. left Summit to enroll in a private school.
    11
    II. PROCEDURAL HISTORY AND
    JURISDICTIONAL ANALYSIS
    While they continued to have C.M. evaluated, C.M.’s
    parents also formally challenged Summit’s adverse eligibility
    decision from February 8, 2016. They did so by filing a due
    process complaint on May 25, 2016, with the Office of Special
    Education of New Jersey’s Department of Education. See
    
    20 U.S.C. § 1415
    (b)(7). That complaint alleged violations of
    the IDEA and § 504 of the Rehabilitation Act.
    The due process complaint prompted an impartial due
    process hearing, see 
    20 U.S.C. § 1415
    (f)(1)(A), which took
    place over several dates between July 2017 and June 2018.
    Seven witnesses testified at the hearing. Both parties
    introduced documentary evidence that Summit’s staff
    considered at the time of the eligibility determination. C.M.’s
    parents introduced the later-prepared reports from Dr.
    McGuffog and Fichtelberg, but the hearing officer did not
    consider them in reaching his determination because Summit
    “did not have this information available at the time of the initial
    determination.” Hearing Officer Final Decision at 18 (Oct. 12,
    2018) (JA50).
    In October 2018 – about fourteen months after Summit had
    formalized an IEP for C.M. – the hearing officer issued a
    decision upholding Summit’s determination that C.M. was not
    eligible for special education as of February 8, 2016. In
    reaching that conclusion, the hearing officer found that
    Summit’s witnesses were “very credible,” id. at 17 (JA49), but
    he discounted the testimony from C.M.’s mother and Dr.
    McGuffog. The problems with C.M.’s mother’s testimony
    were that she was “combative and obstinate,” she “seemed to
    not want to respond,” and she “hesitated sometimes when
    answering simple questions.” Id. The hearing officer also did
    not afford a great deal of weight to Dr. McGuffog’s testimony
    on several grounds: she “appeared upset” that her
    recommendations were not implemented; she dismissed
    12
    C.M.’s report cards without proper justification; and, with
    respect to at least one issue, she did not convey “[a] fair reading
    of her first report.” Id. at 18 (JA50). Substantively, after
    reviewing Summit’s evaluations and considering C.M.’s
    positive responses to the interventions, the hearing officer
    concluded that Summit had satisfied its child-find obligations
    as of February 8, 2016.
    In March 2020, about a year and a half after the hearing
    officer’s dismissal of the due process complaint – and after
    C.M.’s parents had enrolled him in private school in July 2019
    – C.M.’s parents initiated this civil action in the District Court.
    They claimed that Summit violated the IDEA and § 504 of the
    Rehabilitation Act, and they sought several forms of relief.
    Those included compensatory education for the time when
    C.M. was allegedly denied a FAPE (February 2016 through
    August 2017), an order requiring Summit to amend C.M.’s IEP
    to include services and interventions that Dr. McGuffog and
    Fichtelberg recommended after the February 2016 eligibility
    decision, and reimbursement for the costs of C.M.’s private-
    school education. By asserting those claims, the complaint fell
    within the District Court’s subject matter jurisdiction. See
    
    20 U.S.C. § 1415
    (i)(2)(A), (3)(A) (allowing parties aggrieved
    by the decision of a hearing officer after an IDEA due process
    hearing to file a civil action in federal district court); 
    28 U.S.C. § 1331
    ; Mengine v. Runyon, 
    114 F.3d 415
    , 418 (3d Cir. 1997)
    (recognizing that 
    28 U.S.C. § 1331
     grants district courts
    jurisdiction over Rehabilitation Act claims).
    The parties cross-moved for summary judgment, and the
    District Court ruled in Summit’s favor. It held that Summit
    satisfied its child-find obligation and did not violate § 504 of
    the Rehabilitation Act. The District Court also refused to enter
    a declaratory judgment that Summit was responsible for
    C.M.’s private-school tuition because that claim had not been
    exhausted administratively. Finally, the District Court rejected
    the parents’ arguments that the hearing officer’s credibility
    judgments were improper, that the McGuffog and Fichtelberg
    13
    post hoc reports should be considered, and that Summit had to
    amend its IEP.
    The parents timely appealed the District Court’s final order,
    bringing this case within this Court’s appellate jurisdiction.
    See 
    28 U.S.C. § 1291
    .
    III. DISCUSSION
    A. The Denial-of-FAPE Claim Based on a Breach of
    the Child-Find Duty
    As Spending Clause legislation, the IDEA may impose
    conditions on school districts in return for their receipt of
    federal funding. See Arlington Cent. Sch. Dist. Bd. of Educ. v.
    Murphy, 
    548 U.S. 291
    , 295 (2006) (“Congress enacted the
    IDEA pursuant to the Spending Clause.”); see generally
    Pennhurst State Sch. & Hosp. v. Halderman, 
    451 U.S. 1
    , 17
    (1981). Consistent with that constitutional authority, the IDEA
    places two significant responsibilities on school districts with
    respect to children with disabilities: the child-find obligation
    and the duty to provide a free appropriate public education,
    commonly referred to as a ‘FAPE,’ to children with
    disabilities. See D.K. v. Abington Sch. Dist., 
    696 F.3d 233
    , 244
    (3d Cir. 2012) (“[S]chools must: (1) identify children in need
    of special education services (Child Find); and (2) provide
    a FAPE to disabled students.”). 4
    4
    See also 
    20 U.S.C. § 1401
    (3)(A) (defining “child with a
    disability” as having two elements: a qualifying disability
    and a need for special education and related services); N.J.
    Admin. Code § 6A:14-3.5(c) (conditioning eligibility for
    special education and related services on three requirements:
    (i) the child must have a qualifying disability; (ii) the child
    must have a need for special education and related services;
    14
    The child-find obligation requires school districts to
    “identif[y], locate[], and evaluate[]” all “children with
    disabilities . . . who are in need of special education and related
    services.” 
    20 U.S.C. § 1412
    (a)(3)(A); see also 
    id.
     § 1401(29)
    (defining “special education”), (26) (defining “related
    services”). A school district has a duty to evaluate a child for
    a disability upon “notice of behavior that is likely to indicate a
    disability.” D.K., 696 F.3d at 250 (quoting Ridley Sch. Dist. v.
    M.R., 
    680 F.3d 260
    , 271 (3d Cir. 2012)); see also P.P. ex rel.
    Michael P. v. West Chester Area Sch. Dist., 
    585 F.3d 727
    , 738
    (3d Cir. 2009) (explaining that the child-find duty requires
    school districts to evaluate “all students who are reasonably
    suspected of having a disability under the statute[]”). Once a
    school district has such a reasonable suspicion that a child has
    a disability, it has a reasonable time to evaluate “the specific
    problems a potentially disabled student is having.” D.K.,
    696 F.3d at 250; see Ridley, 680 F.3d at 271.
    The IDEA also imposes specific requirements for
    evaluating a child who is reasonably suspected of having a
    disability. In conducting an evaluation, a school district must
    assess the child “in all areas of suspected disability,” 
    20 U.S.C. § 1414
    (b)(3)(B), but that does not require the evaluation to be
    “designed to identify and diagnose every possible disability,”
    D.K., 696 F.3d at 250. See P.P., 
    585 F.3d at
    738–39 (finding
    no child-find violation where a school district failed to identify
    disabilities that were not reasonably suspected at the time).
    Also, a school district’s assessment must seek to gain “relevant
    information” about the “educational needs of the child” to
    determine if the child needs special education and related
    services. 
    20 U.S.C. § 1414
    (b)(3)(C); see also W.A. v. Hendrick
    Hudson Cent. Sch. Dist., 
    927 F.3d 126
    , 145 (2d Cir. 2019)
    (finding no child-find violation where “there was no reason to
    suspect that special education was needed to remedy [the
    child’s] disability”). The IDEA further requires a school
    and (iii) the child’s disability must adversely affect his or her
    educational performance).
    15
    district’s evaluation to be “administered by trained and
    knowledgeable personnel,” 
    20 U.S.C. § 1414
    (b)(3)(A)(iv),
    who must use “a variety of assessment tools and strategies,” 
    id.
    § 1414(b)(2)(A), along with “technically sound instruments,”
    id. § 1414(b)(2)(C). See also id. § 1414(c)(1)(A) (requiring
    school districts to review “data on the child” from several
    different sources). It is not enough for a school district to rely
    on a “single measure or assessment as the sole criterion,” id.
    § 1414(b)(2)(B), or to use assessment methods in ways that are
    not “valid and reliable,” id. § 1414(b)(3)(A)(iii). See also id.
    § 1414(b)(3)(A)(i) (prohibiting the use of evaluation materials
    that are “discriminatory on a racial or cultural basis”). If a
    school district meets these statutory requirements for
    identifying, locating, and evaluating a child with disabilities,
    then it discharges its child-find obligation.
    After identifying a child with a disability who is also in
    need of special education and related services, a school district
    is obligated to provide a FAPE to the disabled child. See
    
    20 U.S.C. § 1412
    (a)(1)(A); see also 
    id.
     § 1401(3) (defining
    “child with a disability”). To do so, a school district, in
    coordination with the child’s parents, should develop an IEP
    and provide special education and related services to the
    disabled child. See Schaffer v. Weast, 
    546 U.S. 49
    , 53 (2005)
    (explaining that “[t]he core of the [IDEA] . . . is the cooperative
    process that it establishes between parents and schools”); see
    also 
    20 U.S.C. § 1401
    (9) (defining “free appropriate public
    education”); 
    id.
     § 1414(d) (defining “individualized education
    program”). Together, the child-find duty and the FAPE
    obligation require public schools to “identify and effectively
    educate” disabled children. P.P., 
    585 F.3d at 735
     (explaining
    further that if disabled children “require specialized services
    that the public institution cannot provide,” then the school must
    “pay for their education elsewhere”).
    The IDEA creates a cause of action against a school district
    that fails to provide a FAPE to a child who has a disability and
    needs special education and related services. See 20 U.S.C.
    16
    § 412(a)(1)(A); id. § 1415(f)(3)(E)(i)–(ii), (i)(2). Due to the
    relationship between the child-find obligation and the duty to
    provide a FAPE, a denial-of-FAPE claim may be premised on
    a child-find violation. 5 Such a claim has three elements. First,
    the child must have a disability for which he or she needs
    special education and related services.           See 
    20 U.S.C. §§ 1412
    (a)(1)(A) (entitling all “children with disabilities” to a
    FAPE), 1401(3)(A) (defining “child with a disability” as a
    child with a qualifying disability and a need for special
    education and related services). Second, the school district
    must breach its child-find duty.                See 
    20 U.S.C. § 1412
    (a)(3)(A); P.P., 
    585 F.3d at 738
    ; Mr. P v. West Hartford
    Bd. of Educ., 
    885 F.3d 735
    , 750 (2d Cir. 2018). Third, the
    school district’s child-find breach must impede the child’s
    right to a FAPE, or, alternatively, the child-find breach must
    either “significantly impede[]” parental participation rights or
    “cause[] a deprivation of educational benefits.” 
    20 U.S.C. § 1415
    (f)(3)(E)(ii)(I)–(III); see D.K., 696 F.3d at 249
    (characterizing a breach of the child-find duty as a procedural
    violation); D.S., 602 F.3d at 565 (recognizing that “[a]
    procedural violation is actionable under the IDEA only if it
    results in a loss of educational opportunity for the student,
    seriously deprives parents of their participation rights, or
    causes a deprivation of educational benefits”).
    To pursue a denial-of-FAPE claim premised on a breach of
    the child-find duty, parents must first file an administrative
    grievance, known as a ‘due process complaint,’ against the
    school district. See 
    20 U.S.C. § 1415
    (b)(6)(A); see also 
    id.
    § 1415(b)(7)(A) (stating that a due process complaint must
    include the child’s name and address, the name of the child’s
    5
    Another recognized category of denial-of-FAPE claims
    encompasses challenges to a school district’s failure to provide
    a FAPE after a school district has determined that a child has a
    disability and is in need of special education and related
    services. See, e.g., Endrew F., 137 S. Ct. at 998–99; D.S. v.

    resolution); Batchelor v. Rose Tree Media Sch. Dist., 
    759 F.3d 266
    , 272 (3d Cir. 2014). A due process complaint may be
    resolved either through mediation, see 
    20 U.S.C. § 1415
    (e)(1),
    or by a hearing officer at a due process hearing, which is an
    impartial state- or local-level administrative adjudicatory
    process, see 
    id.

    Amendment, Due Process and Discrimination Litigation § 6:9
    (Oct. 2019 update); Charles J. Russo & Ralph D. Mawdsley,
    Education Law § 5.07 (2021). Absent the consent of the other
    party, only the grievances presented in the due process
    complaint may be raised by the party who requested the due
    process hearing. See 
    20 U.S.C. § 1415
    (f)(3)(B). After the due
    process hearing, the hearing officer makes findings and
    determinations to resolve the claim. See 
    id.
     § 1415(f)(3)(E).
    A party aggrieved by the hearing officer’s decision may
    commence a civil action in federal district court and seek “such
    relief as the court determines is appropriate.”                  Id.
    § 1415(i)(2)(C)(iii). But a civil action brought in federal court
    after a due process hearing can relate only to “the complaint
    presented” at the hearing. Id. § 1415(i)(2)(A); see Batchelor,
    759 F.3d at 272 (“In the normal case, exhausting the IDEA’s
    administrative process is required in order for the statute to
    grant subject matter jurisdiction to the district court.” (citation,

    extent that the party sought such relief in those proceedings.”).
    When it reviews a hearing officer’s decision, a district court

    preponderance of the evidence. Ridley, 680 F.3d at 268; see

    The civil action brought by C.M.’s parents contains two
    denial-of-FAPE claims, which were presented in their due
    process complaint. Both of those claims are premised on child-
    find violations. First, C.M.’s parents assert that Summit
    violated its child-find obligation by misconstruing the data
    indicating that C.M. had a specific learning disability. Second,
    they claim that Summit breached its child-find duty by not
    further evaluating whether C.M. had autism or ADHD. The
    success of both claims hinges on the second element of a child-
    find claim: a breach of the child-find duty. 6 As explained
    below, Summit did not breach its child-find obligation in either
    respect.
    1. The Claim that Summit Breached Its Child-
    Find Obligation with Respect to Diagnosing
    a Specific Learning Disability
    C.M.’s parents first contend that Summit violated its child-
    find duty by erroneously concluding that C.M. did not have a
    specific learning disability as of February 8, 2016. As defined
    by the IDEA (and similarly by New Jersey regulation), the term
    ‘specific learning disability’ generally means a psychological
    impairment in reading, written or oral expression, or math:
    [It is] a disorder in [one] or more of the basic
    psychological       processes    involved       in
    understanding or in using language, spoken or
    written, which disorder may manifest itself in the
    6
    There is no dispute that C.M. satisfies the other two elements
    of a child-find claim. For the first element, C.M. was
    eventually diagnosed with a disability – autism – for which he
    needed special education and related services. Under the third
    element, Summit did not determine that C.M. qualified for
    special education and related services until April 2017.
    19
    imperfect ability to listen, think, speak, read,
    write, spell, or do mathematical calculations.
    
    20 U.S.C. § 1401
    (30)(A); see also N.J. Admin. Code § 6A:14-
    3.5(c)(12). 7 New Jersey allows school districts to use two
    methods to evaluate a specific learning disability: the severe-
    discrepancy approach and the response-to-intervention
    approach. See N.J. Admin. Code § 6A:14-3.5(c)(12)(i), (ii).
    Under either method, New Jersey requires school districts to
    provide specific documentation of its assessment. See id.
    § 6A:14-3.4(h)(4).
    a. The Severe-Discrepancy Approach to
    Identifying a Specific Learning
    Disability
    The first method for identifying a specific learning
    disability is the severe-discrepancy approach. Consistent with
    its name, that method examines whether there is a severe
    discrepancy “between the student’s current achievement and
    intellectual ability in one or more [areas of academic
    aptitude].” N.J. Admin. Code § 6A:14-3.5(c)(12)(i). If a
    school district uses the severe-discrepancy approach, New
    Jersey requires it to “adopt procedures that utilize a statistical
    formula and criteria for determining severe discrepancy.” Id.
    § 6A:14–3.5(c)(12)(iv). In line with that requirement, Summit
    has determined that a 22-point differential between a child’s
    7
    The IDEA further clarifies that the term ‘specific learning
    disability’ includes “perceptual disabilities, brain injury,
    minimal brain dysfunction, dyslexia, and developmental
    aphasia,” and it excludes “a learning problem that is primarily
    the result of visual, hearing, or motor disabilities, of
    intellectual disabilities, of emotional disturbance, or of
    environmental, cultural, or economic disadvantage.”
    
    20 U.S.C. § 1401
    (30)(B)–(C); see also N.J. Admin. Code
    § 6A:14-3.5(c)(12).
    20
    achievement and intellectual ability constitutes a severe
    discrepancy.
    When he was tested in July and August 2015, C.M.’s
    measured achievement in three areas was below 90, 8 but his
    full-scale IQ was 113. Because C.M.’s scores in those three
    areas were over 22 points below his I.Q. score, he would
    qualify as having a specific learning disability in those three
    areas under the severe-discrepancy approach.
    Critically, however, the IDEA contains a specific exception
    to the severe-discrepancy approach. Under that provision, a
    school district may use the severe-discrepancy method to find
    a specific learning disability, but it is not required to use that
    approach – or even consider the results of that approach for
    child-find purposes:
    [W]hen determining whether a child has a
    specific learning disability as defined in section
    1401 of this title, a local educational agency shall
    not be required to take into consideration
    whether a child has a severe discrepancy
    between achievement and intellectual ability in
    oral expression, listening comprehension,
    written expression, basic reading skill, reading
    comprehension, mathematical calculation, or
    mathematical reasoning.
    
    20 U.S.C. § 1414
    (b)(6)(A) (emphasis added).
    Thus, although New Jersey regulations permit the severe-
    discrepancy method, a school district does not violate its child-
    find obligation by disregarding the results of the severe-
    discrepancy approach. Yet if a school district relies on that
    8
    C.M. measured at 83 in listening comprehension, 89 in
    sentence composition, and 88 in pseudoword decoding.
    21
    approach, then a severe discrepancy establishes only that the
    child has a specific learning disability, and a separate inquiry
    is needed to ascertain whether the student needs special
    education and related services.
    Here, Summit did not violate its child-find obligation by
    not considering the results of the severe-discrepancy approach.
    Summit could have relied on that approach to conclude that
    C.M. had specific learning disabilities in three areas where his
    aptitude scores were below 90. But Summit was not required
    to do so. See 
    20 U.S.C. § 1414
    (b)(6)(A). Nor did it violate its
    child-find duty by giving no consideration to the results of the
    severe-discrepancy approach in assessing C.M. for a specific
    learning disability. See 
    id.
    b. The Response-to-Intervention
    Approach to Identifying a Specific
    Learning Disability
    The second method allowed in New Jersey to evaluate a
    specific learning disability is the response-to-intervention
    approach. That method applies increasingly intensive and
    individualized instruction to a child and evaluates the child’s
    progress in response to that intervention. See 
    20 U.S.C. § 1414
    (b)(6)(B); N.J. Admin. Code § 6A:14–3.5(c)(12)(ii);
    see also Michael P. v. Dep’t of Educ., 
    656 F.3d 1057
    , 1061–62
    (9th Cir. 2011). If the child responds positively to the
    intervention, then he or she does not have a specific learning
    disability for which special education and related services are
    needed. But if the child responds negatively to the intervention
    or responds in a neutral way, then the child does have a specific
    learning disability and is in need of special education and
    related services. Thus, the response-to-intervention approach
    can function as a two-for-one: a negative or neutral response to
    intervention indicates that the child has a specific learning
    disability and is in need of special education and related
    services.
    22
    Through its intervention team, Summit started using the
    response-to-intervention approach a month into C.M.’s first-
    grade year. That team reviewed C.M.’s classroom behavior,
    and then it designed and implemented specific interventions to
    assist him. After implementing the first round of interventions
    for a month and a half, the team evaluated C.M.’s response and
    concluded that the interventions were working well.
    As part of its evaluation of C.M.’s eligibility for special
    education and related services, a broader group of twelve
    members of Summit’s staff reevaluated C.M.’s response to
    Summit’s interventions about two and a half months after
    Summit’s first evaluation. After that more comprehensive
    review, based on a larger data set, that group also determined
    that C.M. had benefited from the interventions and was making
    progress during his first five months of first grade. 9
    On this record, Summit did not violate its child-find duty
    by concluding that C.M. did not have a specific learning
    disability. Both the intervention team and the specially
    assembled evaluation group consisted of “trained and
    knowledgeable personnel.” 
    20 U.S.C. § 1414
    (b)(3)(A)(iv).
    And they gained relevant information about C.M.’s
    educational needs through a recognized method – incremental,
    9
    C.M.’s parents argue that Summit improperly implemented
    the response-to-intervention method in violation of federal and
    New Jersey regulations. They cite 
    34 C.F.R. § 300.309
    (b)(2);
    
    id.
     § 300.311(a)(1), (7); and N.J. Admin. Code § 6A:14-
    3.4(h)(6)(i). But without an explanation as to how those
    alleged procedural violations affected the reliability of
    Summit’s substantive findings, the parents’ argument does not
    provide a basis for discrediting Summit’s reliance on the
    response-to-intervention approach. See D.S., 
    602 F.3d at
    565–
    66 (declining to award relief to parents based on an alleged
    procedural violation where the school district “substantially
    satisfied” the IDEA’s requirements).
    23
    potentially escalating interventions based on different tools and
    strategies. See 
    id.
     § 1414(b)(3)(C), (b)(2)(A). Having met the
    relevant statutory requirements and having observed that
    C.M.’s classroom behavior and academic performance
    improved in response to interventions, Summit met its child-
    find obligations even though it concluded that, as of
    February 8, 2016, C.M. did not need special education and
    related services for a specific learning disability.
    2. The Claim that Summit Breached Its Child-
    Find Obligation by not Evaluating C.M.
    Further for Autism and ADHD
    C.M.’s parents and amici also assert that Summit violated
    its child-find obligation by not specifically evaluating C.M. for
    autism and ADHD by February 8, 2016. 10 Their challenge
    depends on whether Summit had “notice of behavior that is
    likely to indicate” one of those disabilities as of that date. D.K.,
    696 F.3d at 250 (quoting Ridley, 680 F.3d at 271). For context
    on that notice issue, both parties recognize that behavioral
    issues and academic struggles are typical in early childhood,
    especially in the transition to first grade. And although C.M.’s
    parents had Dr. McGuffog administer a battery of sixteen tests
    to C.M. over the summer before he entered first grade, they did
    not alert Summit to C.M.’s behavioral issues before the school
    year. Thus, it was not until after C.M. started first grade that
    Summit had notice of his occasional outbursts, trouble
    maintaining attention, and, later, difficulty with writing. No
    one here contends that those behaviors by a six-year-old child
    transitioning to first grade sufficed to put Summit on notice
    that he may have autism or ADHD. See D.K., 696 F.3d at 251
    10
    The IDEA does not define autism or ADHD, which is an
    abbreviation for attention deficit hyperactivity disorder. But
    New Jersey regulations define ‘autism,’ see N.J. Admin. Code
    § 6A:14–3.5(c)(2), and the term ‘other health impairment,’ as
    defined in the regulation, encompasses ADHD, see id.
    § 6A:14–3.5(c)(9).
    24
    (explaining that, in early primary-school years, “hyperactivity,
    difficulty following instructions, and tantrums are not atypical”
    and that those behaviors alone do not necessarily raise a
    reasonable suspicion that the child has a disability). Rather,
    the dispute centers on Summit’s child-find duty after C.M.’s
    parents shared the McGuffog Report – with its rule-out
    diagnoses for autism and ADHD.
    Amici urge a new rule for rule-out diagnoses. They assert
    that under the child-find duty, a rule-out diagnosis triggers an
    obligation to assess a child specifically for the condition that
    cannot be ruled out. But no such bright-line rule exists under
    the IDEA. And this case demonstrates why. Dr. McGuffog
    declined to conclude that C.M. had autism or ADHD in large
    part due to his young age, and she noted that his academic
    struggles were very new. She also recognized that C.M.
    exhibited a “complex array of neurocognitive strengths and
    weaknesses,” and posed a “diagnostic challenge, particularly
    given his young age.”         McGuffog Neuropsychological
    Evaluation Report at 36 (Oct. 8, 2015) (JA1720). Thus, by its
    own terms, the McGuffog Report concluded that it was too
    early to diagnose C.M. for autism or ADHD – one way or the
    other. In light of that conclusion and without additional
    behavior that indicated a likelihood of autism or ADHD,
    Summit did not violate its child-find duty by not immediately
    evaluating C.M. for those disabilities – especially since doing
    so would involve re-administering several of the same tests that
    Dr. McGuffog administered just months beforehand. 11
    11
    That is not to say that a rule-out diagnosis has no role in the
    child-find analysis: if the rule-out diagnosis is based on reliable
    evaluations and assessments, then, in combination with other
    circumstances, it may contribute to the likelihood that a child
    has a disability. But a rule-out diagnosis alone does not compel
    a school district to conduct additional specific evaluations,
    25
    Without advocating for a bright-line rule, C.M.’s parents
    argue that Summit violated the child-find duty by not
    evaluating C.M. specifically for autism and ADHD before
    classifying him as ineligible for special education and related
    services. But Summit made that eligibility decision only six
    months after Dr. McGuffog evaluated C.M. And without C.M.
    exhibiting appreciably more symptoms, Summit did not breach
    its child-find duty despite its conclusion that C.M. was still too
    young to be evaluated specifically for autism and ADHD.
    C.M.’s parents’ child-find argument comes undone more
    decisively due to Summit’s active response to C.M.’s behavior.
    After C.M.’s parents requested special education, Summit
    began a multidisciplinary assessment of C.M. consisting of
    five separate evaluations, each conducted by a trained and
    knowledgeable professional. Although those tests revealed
    developmental weaknesses, none were significant, and they
    were offset by evidence of strength and progress. See Ridley,
    680 F.3d at 272 (“[J]ust because a child has an area of
    weakness, it doesn’t necessarily mean that she has a disability.”
    (citation and alteration omitted)).
    In addition to those five multidisciplinary evaluations,
    Summit intervened to address C.M.’s behavioral issues. With
    those interventions – which began during C.M.’s first month of
    school, before Dr. McGuffog completed her report or proposed
    any interventions – his social skills started to improve, and his
    incidents of misbehavior became infrequent.
    Similarly, Summit intervened in response to C.M.’s
    emerging academic difficulties. It provided him extra reading
    lessons four days a week and enrolled him in an after-school
    ‘basic skills’ program that met twice a week to reinforce his
    reading and math skills. Afterwards, C.M. demonstrated
    much less to re-administer the same tests that led to the rule-
    out diagnosis.
    26
    measurable improvement in fifteen areas of academic
    performance.
    Based on the additional five multidisciplinary evaluations
    and the progress that C.M. was making without special
    education in both areas of concern (his problematic behaviors
    and his emerging academic struggles), Summit did not breach
    its child-find obligations by concluding that C.M. did not need
    special education as of February 8, 2016. See D.K., 696 F.3d
    at 252 (upholding a finding that no child-find violation
    occurred where the school district’s faculty “did not neglect
    [the child’s] difficulties” but rather “took proactive steps to
    afford him extra assistance and worked closely with his parents
    to maximize his potential for improvement”); Ridley, 680 F.3d
    at 272 (holding that no child-find violation occurred where the
    school district “appeared to be invested in addressing [the
    child’s] needs and provid[ed] appropriate instruction and
    interventions before rushing to special education
    identification”).
    3. The Parent’s Remaining Arguments Against
    the District Court’s Rejection of Their IDEA
    Claim Do Not Succeed.
    a. The District Court Did Not
    Improperly Exclude Evidence of
    Facts that Arose After Summit
    Initially Denied Eligibility.
    C.M.’s parents argue that the District Court improperly
    excluded evidence of facts that arose after February 8, 2016,
    the date that Summit determined that C.M. was ineligible for
    special education and related services. Specifically, C.M.’s
    parents sought to introduce a total of five reports that were
    written after that adverse eligibility determination: three
    reports from Dr. McGuffog that related to her multiple
    evaluations of C.M. between July 2016 and February 2017, and
    two reports from Alana Fichtelberg (the speech pathologist)
    27
    relating to evaluations of C.M. in July 2016 and February 2017.
    The purpose for introducing those reports was to prove “that
    Summit’s ineligibility determination was manifestly
    unreasonable.” Appellants’ Br. 43. The District Court did not
    abuse its discretion in declining to supplement the record with
    those reports.
    In challenging the outcome of a due process hearing in a
    federal district court, a party may seek to supplement the record
    with additional evidence. See 
    20 U.S.C. § 1415
     (i)(2)(C)(ii).
    But a district court has discretion to exclude evidence that is
    irrelevant, cumulative, or otherwise unhelpful. See D.K.,
    696 F.3d at 253 (“[T]he court need not consider evidence that
    is irrelevant or cumulative . . . .” (citation omitted)); see also
    Susan N., 
    70 F.3d at 760
     (“While a district court appropriately
    may exclude [post hoc] evidence, a court must exercise
    particularized discretion in its rulings so that it will consider
    evidence relevant, non-cumulative and useful in determining
    whether Congress’ goal has been reached for the child
    involved.”). 12
    Under the relevance standard, a district court may exclude
    post hoc evidence offered to prove a breach of a school
    district’s child-find obligation. The IDEA specifies that a
    school district’s child-find duty requires a review of “existing
    evaluation data on the child.” 
    20 U.S.C. § 1414
    (c)(1)(A)
    (emphasis added); see also N.J. Admin. Code § 6A:14-3.5(c)
    (requiring eligibility determinations to “be based on all
    12
    See also Maggie Wittlin, Hindsight Evidence, 
    116 Colum. L. Rev. 1323
    , 1389 (2016) (explaining that “the Third Circuit . . .
    considers hindsight evidence only to the extent that it is
    relevant” to IDEA issues); Note, Dennis Fan, No IDEA What
    the Future Holds: The Retrospective Evidence Dilemma,
    
    114 Colum. L. Rev. 1503
    , 1540 (2014) (explaining that the
    “rule allowing retrospective evidence as articulated by the
    Third Circuit . . . is best stated as a relevance rule”).
    28
    assessments conducted” up to the point of decision (emphasis
    added)). Thus, the child-find duty is based on the “snapshot of
    the student’s condition at the time of the” school district’s
    child-find determinations. Lisa M. v. Leander Indep. Sch.
    Dist., 
    924 F.3d 205
    , 215 (5th Cir. 2019); see also L.J. v.
    Pittsburg Unified Sch. Dist., 
    850 F.3d 996
    , 1004 (9th Cir.
    2017). And evidence of a child’s behaviors or test results
    outside of that snapshot – such as reports that did not exist
    when a school district decided not to evaluate a child or when
    a school district denied eligibility – are not relevant to whether
    the school district breached its child-find obligations.
    But not all facts arising after an adverse eligibility decision
    are irrelevant. Later-occurring facts may be relevant to other
    elements of a denial-of-FAPE claim premised on a breach of
    the child-find duty. For example, such facts may be relevant
    to whether the child had a disability. Similarly, evidence of
    later-occurring facts may be relevant to determining how long
    or to what degree a school district denied a FAPE to a disabled
    child.
    Here, the five later-in-time reports were not proffered to
    prove that C.M. was disabled or to establish the amount of time
    that Summit did not provide special education and related
    services. Instead, those reports of C.M.’s performance on
    subsequent tests sought to show that the school district
    breached its child-find obligation. Yet, as explained above, the
    reports are irrelevant to that issue. Accordingly, the District
    Court did not abuse its discretion in excluding the five reports
    from the record after “considering” them and finding that they
    are not “relevant.” J.M. v. Summit City Bd. of Educ., 
    2020 WL 6281719
    , at *7 (D.N.J. Oct. 27, 2020). 13
    13
    Our dissenting colleague fears that preventing the use of post
    hoc evidence to prove a breach of the child-find duty
    “encourages schools to conduct cursory evaluations in the first
    instance.” Dissent at 7–8. He would extend precedent from
    29
    b. The District Court Did Not Err in
    Crediting the Hearing Officer’s
    Adverse Credibility Determinations.
    C.M.’s parents also contend that the District Court erred by
    deferring to the hearing officer’s negative credibility
    determination with respect to Dr. McGuffog’s testimony at the
    due process hearing.
    As a general principle, a reviewing court deferentially
    reviews a fact-finder’s assessment of a witness’s credibility.
    See Cooper v. Harris, 
    137 S. Ct. 1455
    , 1474 (2017) (explaining
    that appellate courts “give singular deference to a trial court’s
    judgments about the credibility of witnesses” because “the
    various cues that ‘bear so heavily on the listener’s
    understanding of and belief in what is said’ are lost on an
    appellate court later sifting through a paper record” (quoting
    Anderson v. Bessemer City, 
    470 U.S. 564
    , 575 (1985))). And
    in the IDEA context, when a federal court reviews a hearing
    officer’s credibility determination, it must credit that
    assessment “unless the nontestimonial, extrinsic evidence in
    the record would justify a contrary conclusion.” D.K.,
    other areas of IDEA jurisprudence to the child-find context.
    But the IDEA precludes that approach in the child-find context
    because the child-find obligation requires school districts to
    review “existing evaluation data on the child.” 
    20 U.S.C. § 1414
    (c)(1)(A) (emphasis added). And the irrelevance of post
    hoc evidence in assessing a child-find breach does not
    legitimatize cursory evaluations. To the contrary, this Circuit’s
    jurisprudence already recognizes that if a school district
    conducts “a poorly designed and ineffective round of testing”
    or fails to evaluate a child when “school officials are on notice
    of behavior that is likely to indicate a disability,” then the
    school district breaches its child-find obligation. D.K.,
    696 F.3d at 250; see also 
    20 U.S.C. § 1414
    (b)(3)(B) (requiring
    school districts to evaluate “in all areas of suspected
    disability”).
    30
    696 F.3d at 243 (quoting Shore Reg’l High Sch. Bd. of Educ. v.
    P.S., 
    381 F.3d 194
    , 199 (3d Cir. 2004)); see also Ridley,
    680 F.3d at 273 n.7.
    Here, C.M.’s parents identify no nontestimonial, extrinsic
    evidence that contradicts the hearing officer’s adverse
    credibility determinations. Without a valid basis to diverge
    from the hearing officer’s negative credibility assessments, the
    District Court did not err.
    c. The District Court Did Not Err by
    Rejecting the Claim for Declaratory
    Judgment.
    C.M.’s parents further contend that the District Court erred
    by not entering a declaratory judgment related to two events
    that took place after they filed their due process complaint.
    Specifically, C.M.’s parents seek a judgment declaring that
    Summit should have implemented additional interventions in
    its later-developed IEP for C.M. and that Summit owes them
    the costs of private-school tuition. Since those events had not
    occurred when C.M.’s parents filed their due process
    complaint, they were not raised in the due process complaint.
    Yet without the consent of the opposing party, which Summit
    did not provide, a due process complaint limits the scope of the
    issues that may be raised at the due process hearing and later
    reviewed in court. See 
    20 U.S.C. § 1415
    (f)(3)(B) (preventing
    the party who requests the due process hearing from raising
    “issues at the due process hearing that were not raised in the
    [due process complaint]” without the other party’s consent); 
    id.
    § 1415(i)(2)(A) (providing that a party aggrieved by the
    hearing officer’s findings and decision may bring a civil action
    “with respect to the [due process] complaint presented”).
    C.M.’s parents could have sought to amend their due process
    complaint once those events occurred.           See 
    20 U.S.C. § 1415
    (c)(2)(E) (describing options for amendment); N.J.
    Admin. Code § 6A:14-2.7(i) (same). Or they could have
    challenged those events through a separate, later-in-time due
    31
    process complaint. But they did neither. Without doing so,
    they are not entitled to a declaratory judgment on either issue,
    and the District Court did not err in rejecting their request for
    such relief.
    B. The District Court Did Not Err in Rejecting the
    Claim Under § 504 of the Rehabilitation Act.
    C.M.’s parents also appeal the District Court’s rejection of
    their claim under § 504 of the Rehabilitation Act. See
    
    29 U.S.C. § 794
    . They have not presented any evidence unique
    to that claim either at the administrative level or in the District
    Court. Rather, they assert a § 504 cause of action purely as a
    companion to their denial-of-FAPE claim. Due to the
    similarities between the two statutes, it is possible for the same
    underlying facts to establish liability for a denial-of-FAPE
    claim under the IDEA and a violation of § 504 of the
    Rehabilitation Act.
    The IDEA and § 504 have several common characteristics.
    Both statutes apply to public schools that receive federal
    financial assistance. See 
    20 U.S.C. §§ 1412
    , 1413; 
    29 U.S.C. § 794
    (b)(2)(B). And both protect persons with disabilities.
    See Endrew F., 
    137 S. Ct. at 993
     (stating that “[a] State
    covered by the IDEA must provide a disabled child with . . .
    special education and related services”); Ridgewood Bd. of
    Educ. v. N.E., 
    172 F.3d 238
    , 253 (3d Cir. 1999) (explaining
    that § 504 “prohibits discrimination on the basis of disability
    in federally funded programs”). Moreover, this Circuit allows
    relief under both causes of action as long as the § 504 claim is
    presented in the due process complaint consistent with the
    IDEA’s exhaustion requirement. See 
    20 U.S.C. § 1415
    (l);
    Wellman v. Butler Area Sch. Dist., 
    877 F.3d 125
    , 131–34 (3d
    Cir. 2017).
    The two statutes also differ in important respects. They
    define the term ‘disability’ differently.            Under the
    Rehabilitation Act, the child’s disability must limit a major life
    32
    activity, but the IDEA does not have that requirement.
    Compare 
    29 U.S.C. § 794
    (a) (incorporating the definition of
    “disability” from the Americans with Disabilities Act), with
    
    20 U.S.C. § 1401
    (3); see also Batchelor, 759 F.3d at 269 n.4
    (“Section 504 defines disability more broadly than the IDEA,
    and thus, some students covered by Section 504 are not
    covered under the IDEA.”); B.C. v. Mount Vernon Sch. Dist.,
    
    837 F.3d 152
    , 159 (2d Cir. 2016) (explaining that, by defining
    ‘disability’ differently, the IDEA and § 504 impose “distinct
    legal standards” and “provide for different inquiries”). The
    statutes also impose different duties to protect persons with
    disabilities. Central to the IDEA’s protection of children with
    disabilities are the affirmative child-find and FAPE duties, see
    
    20 U.S.C. § 1412
    (a)(1)(A), (a)(3)(A), but § 504 protects
    persons with disabilities by making it illegal for a federally
    funded program to discriminate against a disabled person
    solely by reason of his or her disability, see 
    29 U.S.C. § 794
    (a).
    See generally Fry v. Napoleon Cmty. Schs., 
    137 S. Ct. 743
    , 756
    (2017) (“[T]he IDEA guarantees individually tailored
    educational services, while Title II and § 504 promise non-
    discriminatory access to public institutions.”); Matula, 67 F.3d
    at 492 (“While [the] IDEA is phrased in terms of a state’s
    affirmative duty to provide a free, appropriate public
    education, the Rehabilitation Act is worded as a negative
    prohibition against disability discrimination in federally
    funded programs.”). The IDEA also identifies several specific
    components of the affirmative duties that it imposes, see, e.g.,
    
    20 U.S.C. § 1412
    (a)(3)(A) (describing the child-find duty); 
    id.
    § 1412(a)(1)(A) (requiring a participating state to provide a
    FAPE to disabled children); id. § 1414 (listing evaluation
    procedures and requirements), while § 504 requires a showing
    that disability discrimination was the sole cause of a denial of
    a benefit, see U.S.C. § 794(a). Also, the statutes differ in the
    relief that plaintiffs can obtain, most notably with § 504
    allowing plaintiffs to recover compensatory damages when
    they can show that the “discrimination was intentional.” D.E.
    v. Cent. Dauphin Sch. Dist., 
    765 F.3d 260
    , 269 (3d Cir. 2014)
    (explaining further that a showing of “negligence or
    33
    bureaucratic inaction” does not suffice for intentional conduct
    (quoting S.H. v. Lower Merion Sch. Dist., 
    729 F.3d 248
    , 263
    (3d Cir. 2013))); cf. Chambers v. Sch. Dist. of Phila. Bd. of
    Educ., 
    587 F.3d 176
    , 186 (3d Cir. 2009) (holding that
    “compensatory and punitive damages are not an available
    remedy under the IDEA”).
    Depending on the factual basis for a denial-of-FAPE claim,
    the legal differences between the IDEA and § 504 may be of
    no moment. A child could meet both definitions of disability,
    bring a claim that falls into the overlapping space between the
    IDEA’s affirmative duty and § 504’s negative duty, and show
    that disability discrimination was the sole cause for the denial
    of a FAPE. In those circumstances, liability for a denial-of-
    FAPE will also result in liability under § 504. See P.P.,
    
    585 F.3d at
    735–36; Ridgewood Bd. of Educ., 
    172 F.3d at 253
    ;
    Andrew M. v. Del. Cnty. Off. of Mental Health & Mental
    Retardation, 
    490 F.3d 337
    , 349 (3d Cir. 2007). But a denial of
    a FAPE is not a per se violation of § 504. See Andrew M.,
    
    490 F.3d at 349
    .
    For this case, it is not necessary to analyze whether the
    § 504 claim may be brought as a companion to the denial-of-
    FAPE claim. That is so because C.M.’s parents do not succeed
    on their denial-of-FAPE claim, and they offer no additional
    evidence in support of their § 504 claim. Thus, even if the facts
    of this case rendered the legal differences between the two
    statutes immaterial, the failure of the denial-of-FAPE claim
    would still foreclose the § 504 claim. Accordingly, the District
    Court did not err in rejecting C.M.’s parents’ claim under § 504
    of the Rehabilitation Act.
    ***
    For the foregoing reasons, we will affirm the judgment of
    the District Court.
    34
    GREENAWAY, JR., Circuit Judge, dissenting.
    The purpose of the Individuals with Disabilities
    Education Act (“IDEA”) is to provide equality of educational
    opportunity for children with special challenges. Information
    regarding a child’s capabilities is key to determining whether
    that child qualifies as disabled and what constitutes an
    appropriate educational plan.             When experts provide
    information that can facilitate the provision of an appropriate
    educational plan, the school decisionmakers should be armed
    with it so they can make an informed judgment. This is
    especially true where expert reports are post-hoc—meaning
    created after the initial eligibility determination—because they
    are prepared when a child’s challenges persist and may be more
    comprehensive as well as the product of more time and money
    relative to the information upon which the initial eligibility
    determination was based.
    I believe that the District Court erred in excluding five
    reports that were prepared in connection with evaluations of
    C.M. that took place after Summit’s February 8, 2016 adverse
    eligibility determination. Those reports could have been
    relevant in determining whether the school district satisfied its
    duty to provide C.M. with a free appropriate public education
    (“FAPE”). We should accordingly vacate and remand the
    cause to the District Court so that it can apply the appropriate
    standard in considering whether to rely on this post-hoc
    evidence. I therefore dissent.
    When Congress enacted the IDEA, its purpose was to
    ensure that states receiving federal education funding provided
    students a FAPE. 
    20 U.S.C. § 1414
    (d)(1)(A). The FAPE
    mandate applies with equal force to children with disabilities.
    Pursuant to their child-find obligation, school districts must
    1
    “identif[y], locate[], and evaluate[]” children with disabilities,
    
    20 U.S.C. § 1412
    (a)(3)(A), and assess them “in all areas of
    suspected disability,” § 1414(b)(3)(B). Schools satisfy their
    duty to provide a FAPE to children with disabilities by
    developing an Individualized Education Plan (“IEP”). 
    20 U.S.C. § 1414
    (d). The IDEA’s purpose can be realized only if
    schools vigilantly seek to identify signs of disability—whether
    they be behavioral or academic—and tailor a child’s education
    accordingly to facilitate educational progress.
    In holding that courts can essentially summarily exclude
    post-hoc evidence bearing on whether a school district
    breached its child-find obligation, I fear that we may have
    created a loophole that undermines the IDEA’s purpose and
    insulates school districts from liability under the IDEA.
    I begin my analysis with the text of the IDEA itself. The
    IDEA provides that “[a]ny party aggrieved by the
    [administrative] findings and decision” has the right to bring a
    civil action during which the court “shall hear additional
    evidence at the request of a party.”              
    20 U.S.C. § 1415
    (i)(2)(C)(ii). Although we have limited our review to
    then-existing evidence in some scenarios, we have also
    interpreted “additional evidence” to include post-hoc evidence
    in others.
    For instance, we have considered post-hoc evidence in
    evaluating the reasonableness of an IEP. In Fuhrmann ex rel.
    Fuhrmann v. E. Hanover Sch. Dist. Bd. of Educ., we held that
    “evidence of a student’s later educational progress may be
    considered only in determining whether the original IEP was
    reasonably calculated to afford some educational benefit”
    when offered. 
    993 F.2d 1031
    , 1040 (3d Cir. 1992). For other
    inquiries relating to an IEP, the snapshot rule, which bars post-
    2
    hoc evidence, applies. Under that rule, “the measure and
    adequacy of an IEP can only be determined as of the time it is
    offered to the student, and not at some later date.” 
    Id.
    In Susan N. v. Wilson Sch. Dist., we extended
    Fuhrmann beyond the IEP context to the broader IDEA
    eligibility context. In that case, we held that the district court
    erred in summarily excluding additional evidence that was not
    available when a school district determined that a child was
    ineligible for special education. 
    70 F.3d 751
    , 755, 759-62 (3d
    Cir. 1995). Extending Fuhrmann, we held that “after-acquired
    evidence . . . should be used by courts only in assessing the
    reasonableness of the district’s initial decisions regarding a
    particular IEP or the provision of special education services at
    all.” 
    Id. at 762
     (emphasis added).
    Of note, Susan N. requires courts to consider the post-
    hoc evidence—it does not require courts to incorporate that
    evidence into its findings. Specifically, it provides:
    While a district court appropriately may exclude
    additional evidence, a court must exercise particularized
    discretion in its rulings so that it will consider evidence
    relevant, non-cumulative and useful in determining
    whether Congress’ goal has been reached for the child
    involved. Consequently, on the remand the district
    court should use this standard in determining whether to
    admit the proffered additional evidence, i.e., would the
    evidence assist the court in ascertaining whether
    Congress’ goal has been and is being reached for the
    child involved.
    3
    
    Id. at 760
    . 1 While courts are required to consider post-hoc
    evidence, they must also heed Susan N.’s warning to review
    that evidence “carefully” given the “dangers inherent in . . .
    second-guessing the decisions of a school district with
    information to which it could not possibly have had access at
    the time it made those decisions.” 
    Id. at 762
    .
    My colleagues in the majority assert that the snapshot
    rule applies to child-find obligations, citing Lisa M. v. Leander
    Indep. Sch. Dist., 
    924 F.3d 205
    , 215 (5th Cir. 2019) and L.J. v.

    , 1004 (9th Cir.
    2017). According to the majority, it follows that “evidence of
    a child’s behaviors or test results outside of that snapshot . . .
    are not relevant to whether the school district breached its
    child-find obligations.” Majority Op. 35. This means that a
    court can exercise its discretion to exclude the post-hoc
    evidence offered to prove breach because it is irrelevant. See
    D.K. v. Abington Sch. Dist., 
    696 F.3d 233
    , 253 (3d Cir. 2012)

    We have also applied the Susan N. inquiry outside of the IEP
    context. In D.K. v. Abington Sch. Dist., we declined to
    summarily exclude post-hoc evidence—namely, an expert
    report opining on the appropriateness of a school district’s
    response to a child’s behavioral incidents—offered to support
    a claim that the school district failed to provide a child with a
    FAPE before it designed an IEP for that child. 
    696 F.3d 233
    ,
    243 (3d Cir. 2012). Although we ultimately excluded the
    evidence because it was duplicative, our rejection of the
    snapshot rule shows that Susan N. applies beyond the IEP
    context and to the broader IDEA context. See id. at 253.
    Accordingly, applying Susan N. to the propriety of an
    eligibility determination is not an unprincipled extension of our
    precedent.

    (“[T]he court need not consider evidence that is irrelevant . . .
    .” (citation omitted)). By declaring that post-hoc evidence is
    irrelevant to the issue of a school district’s child-find breach
    under the snapshot rule, the majority essentially gives courts
    carte blanche to summarily reject that evidence.
    Initially, we are not bound by Lisa M. or L.J., both of
    which are out-of-circuit decisions. We are, however, bound by
    Fuhrmann as well as Susan N.’s extension of Fuhrmann to the
    broader IDEA eligibility context. If the majority had applied
    Susan N., it would be hard pressed to explain why post-hoc
    reports prepared in connection with evaluations of a child and
    providing disability diagnoses are irrelevant to whether a
    school district breached its child-find obligation—namely, its
    duty to “identif[y], locate[], and evaluate[]” children with
    disabilities, 
    20 U.S.C. § 1412
    (a)(3)(A), and to provide them
    with a FAPE, 
    20 U.S.C. § 1414
    (d).
    That the majority would allow consideration of post-hoc
    evidence with regard to other elements of a denial-of-FAPE
    claim—such as whether the child has a disability or
    determining the extent to which a school district denied a
    FAPE—is of no moment. The evidence existing at the time of
    the eligibility determination may be cursory or under-
    developed, rendering families unable to demonstrate the school
    district’s breach. Because breach is a required element of a
    denial-of-FAPE claim, the inability to use post-hoc evidence
    to show breach could prove fatal to the entire claim. 2
    2
    As the majority explained, there are three required elements
    of a denial-of-FAPE claim. First, the child must have a
    disability for which he or she needs special education and
    related services. See 
    20 U.S.C. §§ 1412
    (a)(1)(A). Second, the
    5
    Here, both the District Court and Administrative Law
    Judge (“ALJ”) rejected the post-hoc evidence, and our review
    of that legal conclusion is de novo. T.R. v. Kingwood Twp. Bd.
    of Ed., 
    205 F.3d 572
    , 576 (3d Cir. 2000). The ALJ upheld
    Summit’s eligibility determination based on the snapshot rule,
    citing Fuhrmann. The ALJ reasoned that because Summit
    “used all information available to it at the time of the eligibility
    meeting on February 8, 2016,” it satisfied that rule. J.A. 56.
    Likewise, the District Court applied the snapshot rule,
    reasoning that eligibility “is a snapshot of the student’s
    condition at the time of the eligibility determination.” J.A. 16
    (quoting Lisa M., 924 F.3d at 215 (internal footnote omitted)).
    Given that a student’s condition as of the eligibility
    determination is all that matters under the snapshot rule, the
    District Court concluded that the post-hoc reports were not
    “relevant to the ALJ’s decision.” J.A. 15-16. Further, the
    District Court declined to rely on Susan N., noting that Susan
    N.’s holding is limited to the reasonableness of an IEP. 3
    school district must breach its child-find duty in a manner that
    impedes the child’s right to a FAPE. See D.K., 696 F.3d at
    250. Third, the school district’s child-find violation must
    deprive the disabled child of needed special education and
    related services, thereby denying the child a FAPE. See 
    20 U.S.C. § 1415
    (f)(3)(E)(i)-(ii).
    3
    The District Court cited D.S. v. Bayonne Bd. of Educ. for this
    proposition. However, that case involved the appropriateness
    of an IEP, so we had no occasion to discuss the type of
    evidence that could be used to determine the accuracy of an
    IDEA eligibility determination. See 
    602 F.3d 553
    , 555-56 (3d
    Cir. 2010). The District Court also cited Lisa M. v. Leander
    Indep. Sch. Dist., which limits the review of an eligibility
    determination to information available at the time of evaluation
    6
    According to the District Court, there is “good reason not to
    extend Susan N. here: unlike the eligibility determination, the
    reasonableness of an IEP is measured by “staff implementation
    and student performance over a period of time.” J.A. 16
    (quoting Lisa M., 924 F.3d at 215 (internal footnote omitted)).
    In excluding the post-hoc evidence, the District Court
    analyzed the relevance of the post-hoc reports under the wrong
    standard. As a threshold matter, Susan N. applies because the
    IDEA eligibility determination constitutes “the provision of
    special education services at all.” See 
    70 F.3d at 762
    . What
    else could “at all” refer to or mean if not the eligibility
    determination itself? “[T]he provision of special education
    services at all” hinges on the eligibility determination. If a
    school district finds a child ineligible for special education, the
    inquiry ends—the school will not provide special education
    services. If, however, the school district finds the child
    eligible, it will provide special education services.
    Accordingly, the District Court should have analyzed whether
    the post-hoc reports are “relevant, non-cumulative and useful”
    in determining whether Congress’ goal—to ensure that
    Summit provided C.M. with a FAPE—was being met. See 
    id.
    Untethered to the snapshot rule, it does not necessarily follow
    that the post-hoc reports would be irrelevant. The District
    Court would have the discretion to exclude the reports, but only
    after making appropriate inquiry. Its failure to meaningfully
    consider the post-hoc evidence based on the snapshot rule
    constitutes error.
    because “[s]ubsequent events do not determine ex ante
    reasonableness in the eligibility context.” 
    924 F.3d 205
    , 214-
    15 (5th Cir. 2019). That case is not binding.

    The majority’s departure from our own precedent leaves
    children with disabilities in a vulnerable position and
    jeopardizes their educational progress. It also gives school
    districts perverse incentives. Specifically, it encourages
    schools to conduct cursory evaluations in the first instance
    without concern for liability based on more thorough expert
    evaluations that diagnose students with disabilities and occur
    after the child has been found ineligible for special education.
    For instance, envision a school district that is confronted
    with a young child exhibiting a persistent inability to pay
    attention during class. On one hand, that behavior could be
    construed as normal behavior for a child of that age. On the
    other, that behavior could signal a disability. Knowing that its
    special eligibility determination for that child will be measured
    against only the information available at the time of the
    decision, the school district may be inclined to perform a
    perfunctory examination of the child in order to save time and
    resources. After all, the school district can ostensibly attribute
    those attention deficit issues to the child’s preference for
    socializing over addition and subtraction—a preference likely
    shared by many of his or her classmates. Then, months later,
    if a third-party were to conduct a comprehensive evaluation
    and diagnose that child with a disability, that child’s family
    would be unable to use the diagnosis as evidence that the
    school district breached its duty to provide a FAPE. According
    to the majority, that evidence would be irrelevant. The school
    district would be insulated from liability, and the child will
    have sustained years of an inadequate education with no
    recourse.
    The District Court should have considered whether the
    post-hoc reports diagnosing C.M. with disabilities would assist
    in determining whether Summit had provided a FAPE to C.M.

    as opposed to rejecting them as irrelevant under the snapshot
    rule. I respectfully dissent.
