    APPEALS FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MAINE
    [Hon. George Z. Singal, U.S. District Judge]
    Before
    Barron, Chief Judge,
    Lynch and Gelpí, Circuit Judges.
    Eric R. Herlan, with whom Drummond Woodsum & MacMahon was on
    brief, for appellant and cross-appellees.

    August 9, 2022
    BARRON, Chief Judge.        The Falmouth School Department
    ("Falmouth") appeals from an order of the United States District
    Court for the District of Maine that concerns the Individuals with
    Disabilities Education Act (the "IDEA").        The order rejects a
    challenge to a ruling by a Maine Department of Education due
    process hearing officer (the "hearing officer") that Falmouth
    violated the IDEA and that Falmouth was therefore required to
    reimburse Mr. and Mrs. Doe (the "Does"), the appellees here, for
    the cost of their son John's tuition at a private school in which
    they had placed him.   Separately, the Does bring a cross-appeal
    that challenges the District Court's order that dismisses their
    counterclaims in Falmouth's IDEA action, which the Does bring
    against Falmouth under the Americans with Disabilities Act (the
    "ADA") and Section 504 of the Rehabilitation Act (the "RHA"), and
    against Gene Kucinkas, Falmouth's Director of Special Education,
    under 
    42 U.S.C. § 1983
    .   We affirm.
    I.
    A.
    To receive federal funds under the IDEA, states are
    generally required to make a "free appropriate public education"
    (a "FAPE") "available to all children with disabilities residing
    in the State."   
    20 U.S.C. § 1412
    (a)(1)(A).       Maine has accepted
    funds under the IDEA and required local educational agencies such
    - 2 -
    as Falmouth to provide a FAPE to eligible children within their
    jurisdictions.        Me. Stat. tit. 20A, §§ 7006, 7202.
    "[T]he centerpiece of the [IDEA's] education delivery
    system for disabled children" is the Individualized Education
    Program ("IEP").           Endrew F. ex rel. Joseph F. v. Douglas Cnty.

    , 994 (2017) (quoting Honig v. Doe,
    
    484 U.S. 305
    , 311 (1988)).              The child's "IEP team" develops the
    IEP,    which    is   "a      written   statement       for     each     child   with   a
    disability"      that      must,    among    other     requirements,       detail      the
    child's academic achievement and functional performance, provide
    measurable annual goals for the child, describe how the child's
    progress towards those goals will be measured, and describe what
    services the child will receive.                
    20 U.S.C. § 1414
    (d)(1)(A).             The
    "IEP team" that develops the IEP must include the child's parents,
    their     regular        and       special      education       teachers,        and    a
    "representative          of     the     local       education       agency."           
    Id.
    § 1414(d)(1)(B), (d)(3), (d)(4).
    An IEP must be "reasonably calculated to enable a child
    to     make     progress       appropriate       in     light       of    the    child's
    circumstances."         Endrew F., 
    137 S. Ct. at 999
    .                An IEP must also
    ensure that the child is educated "in the '[l]east restrictive
    environment' appropriate for" that child.                     C.D. ex rel. M.D. v.

    The "least restrictive environment" ("LRE") requirement
    "embod[ies]      a    'preference'          for    'mainstreaming'            students      with
    disabilities         in    'the     regular       classrooms    of       a    public      school
    system.'"      
    Id.
     (quoting Bd. of Educ. v. Rowley, 
    458 U.S. 176
    , 202-
    03 (1982)).      The IEP team, in designing an IEP to ensure that the
    child receives a FAPE, must "choos[e] a placement" in which the
    child   will    receive           educational      instruction       "that       strikes      an
    appropriate balance between the restrictiveness of the placement
    and educational progress."                 Id. at 631.      Under our precedent, we
    "'weigh[]' this preference for mainstreaming 'in concert with the'
    FAPE mandate."            Id. (quoting Roland M. v. Concord Sch. Comm., 
    910 F.2d 983
    , 992-93 (1st Cir. 1990)).
    If the parents of a child who is eligible to receive
    services under the IDEA believe that the child has been denied a
    FAPE,   then    they        may    bring    a   complaint      to    a       state   or    local
    educational agency, as determined by the law of the relevant state.

    , 5 (1st Cir. 2022).                                     If the
    complaint is not resolved informally, the parents are entitled to
    a "due process hearing" in front of that agency at which their
    complaint can be adjudicated.                   
    20 U.S.C. § 1415
    (f)(1)(B).                 Maine
    provides that such due process hearings occur in front of a hearing

    Under the IDEA, "[a]ny party aggrieved by the findings
    and decision made" in the administrative proceeding before the
    state or local educational agency may bring a civil action in state
    or federal court.        
    20 U.S.C. § 1415
    (i)(2)(A).             A District Court
    that entertains such a civil action must undertake what we have
    called "'involved oversight' of the agency's factual findings and
    conclusions." G.D., 27 F.4th at 6 (quoting S. Kingstown Sch. Comm.
    v. Joanna S., 
    773 F.3d 344
    , 349 (1st Cir. 2014)).               A District Court
    that conducts this oversight must review the administrative record
    and, at the request of a party to the action, additional evidence,
    while "accord[ing] 'due weight' to the agency's administrative
    proceedings."      
    Id.
     (quoting Lenn v. Portland Sch. Comm., 
    998 F.2d 1083
    , 1087 (1st Cir. 1993)); see also 
    20 U.S.C. § 1415

    The    District    Court    must   base   its   decision    on   "the

    determines is appropriate."        
    20 U.S.C. § 1415
    (i)(2)(C)(iii).           That
    relief    may,    in   some   circumstances,    include     a    requirement    to
    reimburse parents who "unilaterally change their child's placement
    during the pendency of review proceedings" to a private placement
    for the costs that the parents incur for that placement.                Florence

    We describe "the background facts as supportably found
    by the district court," Sebastian M. v. King Philip Reg'l Sch.
    Dist., 
    685 F.3d 79
    , 82 (1st Cir. 2012); see Falmouth Sch. Dep't v.
    Doe, No. 20-cv-00214, 
    2021 WL 4476939
     (D. Me. Sept. 29, 2021).        We
    focus here on the facts that pertain to Falmouth's appeal of the
    District Court's rejection of Falmouth's challenge to the hearing
    officer's decision that Falmouth denied John a FAPE and the hearing
    officer's   determination   that,    in   consequence,   Falmouth   must
    reimburse the Does for the cost that they incurred by placing John
    in a private school.   In Part V, infra, we recount the allegations
    that are relevant to the Does' cross-appeal of the District Court's
    order that dismissed their counterclaims.
    The hearing officer found that John had been denied a
    FAPE during two periods: January 2018 to March 2019, and September
    2019 to February 2020.      Those months span a period in which
    Falmouth had proposed four separate IEPs for John.        We will refer
    to these IEPs as the January 2018 IEP, the January 2019 IEP, the
    September 2019 IEP, and the November 2019 IEP.
    Before turning to the facts that concern those periods
    of time and those IEPs, however, we first review the events from
    an even earlier period.     That is the period during which John
    received services from Falmouth for the first time under an IEP.
    That initial IEP is not at issue in the IDEA suit that underlies
    - 6 -
    this appeal, but it provides useful context for our consideration
    of the IEPs that are.         We will refer to this first IEP as the
    January 2017 IEP.
    1.
    John enrolled at Falmouth Elementary School for first
    grade in the fall of 2016.            He did so after having attended a
    private preschool and kindergarten.            Soon after, Falmouth became
    aware that John's literacy skills were "at the pre-K level."                And
    then, in November, Falmouth convened an IEP team and the Does
    consented   to     John   receiving    special      education   services   from
    Falmouth.   The January 2017 IEP for John followed thereafter.
    According to      Robin Seeker,         John's special education
    teacher, when John started this specialized instruction under this
    IEP,   in   late    January    2017,    he    was    a   "nonreader."      More
    specifically, he was reading at or below instructional level A on
    the Benchmark Assessment System (the "BAS"), which classifies
    students based on their ability to read independently and with the
    support of an instructor.
    Level A is the lowest level on the BAS.             A child meets
    progress expectations under the BAS if the child is at level D at
    the end of kindergarten or the beginning of first grade and if the
    child is at level J by the end of first grade.
    The January 2017 IEP included a goal that John would
    reach instructional level D on the BAS by February 2018, which is
    - 7 -
    a level that corresponds to "an end of kindergarten reading level."
    This IEP provided that John would receive ninety minutes of daily
    instruction from Seeker, with that time split evenly between
    reading, writing, and math.
    The reading instruction that John received while this
    IEP was in place was initially based on the Wilson "Fundations"
    program.     However, Seeker soon began using the "SPIRE" program
    instead.
    Falmouth and the Does agreed to amend the January 2017
    IEP   in   April   2017   to   add   summer   programming.   Following   a
    psychological evaluation that diagnosed John with ADHD, the IEP
    team met again in May 2017 to review the evaluation.          Notes from
    that meeting indicate that John was "reading at the instructional
    level C on the [BAS]" and "working on learning his basic sight
    words," which the hearing officer defined as words "that 'can't be
    sounded out.'"
    2.
    The January 2017 IEP was set to expire in late January
    2018.      By that time, John had completed approximately half of
    second grade.      He was still "reading instructional levels C and D
    books," and "writing at an end of kindergarten level."          John had
    increased, however, to spelling 50 words on a list of 100 "high
    frequency sight words."
    - 8 -
    In   January     2018,     Seeker    identified    John's   "biggest
    challenge" as being "in the orthographic area."                     Seeker was
    referring to orthographic processing, which the District Court
    explained "refers to the skills necessary 'to store and recall the
    visual forms of letters and words.'"             John also "struggled with
    . . . phonological processing," which "refers to 'the ability to
    perceive, order and manipulate the sounds within words.'"
    John's IEP team met on January 23, 2018 to revise John's
    January 2017 IEP.       The result was the January 2018 IEP.
    This    IEP    increased    the     amount   of   daily   specialized
    instruction that John would receive in reading and writing from
    thirty minutes each to one hour of reading and forty-five minutes
    of writing.      It did not change, however, the type of reading
    instruction that John would receive; it continued to provide for
    John to receive SPIRE programming.
    The January 2018 IEP also did not include a specific BAS
    level as a measurable goal.        The IEP did define as a goal, however,
    that John be able to read the list of 100 "high frequency sight
    words" that was mentioned above with 70% accuracy by February 2019.
    By June 2018, John was still reading "somewhere between
    a BAS level C and D."        He had progressed to the second level of
    the SPIRE program, but he had taken longer to complete the first
    level than any other student Seeker could recall. John could spell
    56 out of the 100 listed "high frequency sight words."
    - 9 -
    That     summer,   Falmouth    again   offered   John     summer
    programming.      However, the Does declined the offer and elected to
    have John tutored at the Children's Dyslexia Center during the
    summer.
    When John began third grade in fall 2018, John's mother
    emailed his new special education teacher, Karen Dunn, to express
    concern about John's lack of progress and to ask about other
    potential programming options.       Dunn, too, was concerned about
    John's lack of progress and had observed "some apparent regression
    in his reading skills" over the summer.
    Dunn shared those concerns with Kucinkas, Falmouth's
    Director of Special Education.      Kucinkas proposed using Lindamood
    Bell   ("LMB")    programming,   which    is,   like   SPIRE,   a   reading
    instruction methodology.      LMB programming includes the "Lindamood
    Phoneme Processing System" ("LiPS") and "Seeing Stars."                This
    proposal was not communicated to the Does.
    At a meeting of John's IEP team in September 2018, John's
    mother raised the concerns that she had raised to Kucinkas.              No
    one on the IEP team, however, suggested any alternative reading
    programming for John apart from SPIRE.          Nonetheless, the January
    2018 IEP was amended at that meeting to add the use of audio books
    to the services that he would receive.
    When John returned to school for third grade, Dunn used
    Wilson "Fundations" materials in instructing John, although the
    - 10 -
    use   of   these    materials   to   instruct    John     was   not   expressly
    referenced in the January 2018 IEP.             Dunn used them to address
    John's apparent reading regression over the summer.
    Later in the fall, however, Dunn switched back to using
    SPIRE to instruct John. By November, John had mastered only twelve
    new sight words.
    Approximately two and a half months before the January
    2018 IEP expired, the Does obtained, on December 9, 2018, a private
    reading evaluation from Lisa Murphy and Barbara Melnick of the
    Aucocisco School, which is a private special education school in
    Maine.     The evaluation "suggested that John . . . struggled with
    both orthographic processing and phonological processing" and
    "assessed    some   core   reading    skills    to   be   at    the   'pre-k   to
    kindergarten levels.'"
    The evaluation recommended "intensive and one on one"
    "intervention."       The evaluation specifically recommended "[t]he
    Lindamood-Bell curriculum of LiPS followed by/overlaid with the
    Seeing Stars Program" to better enable John to make progress.
    The Does provided this evaluation to Falmouth in January
    2019, before the January 2018 IEP had expired.             By then, John had
    added only three more sight words and progressed only to "BAS
    instructional level E (early first grade)."
    - 11 -
    3.
    John's IEP team reconvened for his second annual review
    in January 2019.    The Does submitted a statement of concern in
    advance that discussed what they referred to as the "substantial
    unrecognized   orthographic   processing   deficits"   that   John   had
    according to the Aucocisco evaluation.       They asked that John's
    reading instruction include the "Lindamood-Bell curriculum of
    [LiPS] followed by/overlaid with the Seeing Stars Program," based
    on the Aucocisco evaluation.
    Falmouth thereafter proposed the January 2019 IEP.         The
    January 2019 IEP increased the time John would spend in specialized
    programming at Falmouth Elementary School, such that he would spend
    59% of his time in a regular classroom (as opposed to the 63% he
    had spent in the second IEP year and 77% in his first IEP year).
    The January 2019 IEP also included "some instruction using the
    Lindamood Bell Seeing Stars program."
    Under the January 2019 IEP, John would receive nine hours
    of weekly instruction using the Seeing Stars methodology delivered
    by Shar Mahoney, who had not previously taught John. Mahoney would
    consult with a trainer certified in LMB programming every other
    week for fifty minutes. Falmouth reintroduced a BAS goal for John,
    namely that John achieve BAS level I-J by February 2020.
    At the January 22 meeting of the IEP team and in a letter
    sent two days later, the Does stated that they would remove John
    - 12 -
    from Falmouth Elementary School each afternoon so that he could
    receive intensive reading programming at Aucocisco using LiPS and
    Seeing Stars.      Aucocisco proposed to provide John one-on-one
    instruction for two hours daily.
    In the email enclosing the letter, the Does requested
    that Falmouth adjust John's schedule so that he could remain in
    his mainstream classroom during the mornings while he was receiving
    instruction at Falmouth before leaving to receive instruction at
    Aucocisco in the afternoons.       Kucinkas responded in a letter that
    Falmouth   would   continue   to     provide   John   with   specialized
    instruction during his mornings at Falmouth Elementary School,
    with no change in light of his daily early dismissal.
    4.
    The Does revoked their consent for services under John's
    January 2019 IEP on March 12, 2019.        They requested a plan for
    accommodations under Section 504 of the RHA.1
    Falmouth implemented such a plan (a "504 plan") later
    that month.   John continued to spend his mornings in a mainstream
    Falmouth Elementary classroom and his afternoons at Aucocisco.
    John also received a daily hour of tutoring from Aucocisco staff
    for three weeks during the summer.
    1 A plan offered under Section 504 of the Rehabilitation Act
    provides accommodations for students with disabilities to
    participate in public school education but does not provide
    specialized instruction.
    - 13 -
    John received several evaluations and assessments during
    the spring and summer of 2019. These included a neuropsychological
    evaluation performed by Dr. Marcia Hunter in February and March
    2019 that recommended LMB programming; multiple assessments that
    Falmouth proposed and to which the Does consented in June; an
    evaluation by Aucocisco in July to determine John's progress after
    100 hours of Seeing Stars instruction; and a reading evaluation in
    August by Dr. Jayne Boulos, to whom Falmouth had referred the Does.
    The evaluation of John by Aucocisco concluded that he
    was still reading at a first-grade level but noted gains in his
    ability to read sight words.     Dr. Boulos's evaluation concluded
    that John's reading skills were "well-below average . . . across
    all core domains" and recommended another evaluation from the
    Children's Dyslexia Center, where John had received tutoring the
    previous summer.
    5.
    John began fourth grade in fall 2019 and continued to
    split his school days between Falmouth Elementary School and
    Aucocisco.   He was not then receiving services under the IDEA from
    Falmouth.
    Falmouth and the Does continued to discuss restarting
    those services.    Falmouth proposed a new IEP that would increase
    John's weekly literacy instruction, but Falmouth indicated that it
    - 14 -
    would not offer any LMB programming in the new IEP.        We will refer
    to this IEP as the September 2019 IEP.
    In October 2019, Falmouth assessed John to be at BAS
    instructional level E, an early first grade reading level and the
    same level that he had achieved as of January 2019.                A math
    assessment showed that John had below-grade-level math skills.
    In November 2019, John's IEP team met again.           The Does,
    in advance of this meeting, communicated to Falmouth that John
    required a full-day placement at Aucocisco and that Aucocisco's
    instruction was helping John develop literacy skills.             Falmouth
    proposed an updated IEP that would increase the proposed special
    education in math and add behavioral intervention efforts but would
    not offer any LMB programming.      We will refer to this IEP as the
    November 2019 IEP.
    The Does rejected the proposed IEP and placed John at
    Aucocisco full-time starting on November 4, 2019.          Then Falmouth
    proposed a new IEP in February 2020 -- the February 2020 IEP --
    that the Does do not challenge.
    In   March   2020,   according   to   Melnick,   the   Aucocisco
    director, John was reading at a mid-second grade to early third
    grade level.   In fall 2020, John's report card noted that he was
    practicing reading at a third-grade level.

    C.
    The   Does    submitted     a    hearing   request        to    the    Maine
    Department of Education on January 15, 2020.2                     They argued that
    John had not been provided a FAPE from January 2018 until February
    2020, with the exception of the period from March 2019 to the start
    of John's fourth grade year that fall when he was not receiving
    services      under   the   IDEA   from       Falmouth   because        the   Does     had
    withdrawn their consent to his receipt of them.
    After a five-day hearing in early March 2020, the hearing
    officer concluded that Falmouth had denied John a FAPE from January
    2018 to March 2019 and from September 2019 through February 2020.
    In explaining why, the hearing officer addressed the January 2018,
    January 2019, and September 2019 IEPs.3
    First, the hearing officer determined that the January
    2018 IEP was not "reasonably calculated to provide [John] with a
    FAPE" because of its reliance on SPIRE.                      The hearing officer
    explained that, starting in January 2018, Falmouth had "failed to
    take       . . .    meaningful     steps       to    address      [John's]          unique
    circumstances       and    challenges     with      regard   to   his    orthographic
    The Does had initially filed for a hearing in October 2019,
    2
    but they withdrew that request before the hearing.
    Although the November 2019 IEP was proposed within the
    3
    period that the hearing officer determined John was denied a FAPE,
    neither the hearing officer nor the District Court based any legal
    conclusions on this IEP and the parties make no arguments
    concerning it.
    - 16 -
    processing disability, which by this time was known by [Falmouth]."
    The hearing officer pointed to Falmouth's failure to request
    additional evaluations focused on John's orthographic processing
    and its continued reliance on SPIRE programming, rather than
    "consider[ing] a change in the methodology being used for [John's]
    programming."   The hearing officer, quoting Dunn, specifically
    identified "the Seeing Stars program that Ms. Dunn, Ms. Melnick,
    and others testified was 'specifically designed for children who
    have orthographic dyslexia'" as an alternative methodology.
    Next, the hearing officer turned to the January 2019
    IEP, which the Does rejected.       The hearing officer called that IEP
    "a step in the right direction," but "too little, too late," given
    Falmouth's "reluctance to conduct further evaluations" and its
    staff's lack of "experience[] in delivering" LMB programs.
    Finally, the hearing officer addressed the September
    2019 IEP, and concluded that it "was not reasonably calculated and
    reasonably ambitious to enable [John] to make appropriate progress
    in light of his circumstances."        In support of that conclusion,
    the hearing officer found it "incongruous that [Falmouth] seemed
    to hold out hope that the SPIRE program would work for [John] after
    two years of limited progress," even as it "offer[ed] and then
    abruptly   remove[d]   the   LiPS    program,   declaring   that   it   was
    'ineffective' after [John] had only incorporated it into his
    learning for a period of six months."
    - 17 -
    The hearing officer then determined that "the Aucocisco
    School is an appropriate placement" for John.   And, based on that
    determination, the hearing officer ordered Falmouth to reimburse
    the Does for the cost of John's Aucocisco tuition from January 28,
    2019 to September 2019, and the 2019-2020 school year, along with
    certain other expenses.
    D.
    Falmouth brought an action under the IDEA in the District
    of Maine in which it challenged the hearing officer's ruling that
    John had been denied a FAPE for the periods in question.   Falmouth
    also challenged the remedial order on separate grounds.
    The Does answered and brought counterclaims against
    Falmouth under Section 504 of the RHA and Title II of the ADA.
    The Does also brought a counterclaim against Kucinkas under 
    42 U.S.C. § 1983
     alleging retaliation against them in violation of
    their rights under the First Amendment.   Falmouth moved to dismiss
    the counterclaims under Federal Rule of Civil Procedure 12(b)(6).
    Falmouth moved for summary judgment, as did the Does, as
    to Falmouth's civil action under the IDEA in which it challenged
    the hearing officer's orders in favor of the Does.   See Sebastian
    M., 685 F.3d at 84-85 ("[A] motion for summary judgment in an IDEA
    case is simply a vehicle for deciding the relevant issues.").   The
    District Court granted judgment to the Does, sustaining the hearing
    officer's order finding that John was denied a FAPE during the
    - 18 -
    periods of time in question and holding that the hearing officer's
    order of reimbursement was "an appropriate remedy" for Falmouth
    having denied John a FAPE under those IEPs.
    Falmouth   and   Kucinkas    moved   to   dismiss   the    Does'
    counterclaims against each of them under Federal Rule of Civil
    Procedure 12(b)(6).    In an order issued contemporaneously to its
    order affirming the hearing officer's decision, the District Court
    granted the motion and dismissed the counterclaims.              Falmouth
    timely filed a notice of appeal of the District Court's rulings
    against it and the Does cross-appealed from the dismissal of their
    counterclaims against Falmouth and Kucinkas.
    II.
    Falmouth brings various challenges that apply to the
    District Court's ruling with respect to both of the periods of
    time in which the hearing officer found that Falmouth denied John
    a FAPE.   In some of them, Falmouth does so without focusing on any
    ruling by the District Court that concerns only a specific period
    within that overall time span rather than the time span as a whole.
    In those broadly applicable challenges, Falmouth alleges that the
    District Court's assessments of the specific IEPs that Falmouth
    had proposed for John during that overall time span were plagued
    by flaws that apply equally to each of those assessments.            We thus
    begin our analysis by examining this set of contentions, before
    then turning to the more time-period-specific challenges that
    - 19 -
    Falmouth also brings to the District Court's ruling that John was
    denied a FAPE and that direct our attention to the District Court's
    assessments of certain ones of the IEPs at issue.
    "We review the district court's determinations of law de
    novo, and its findings of fact for clear error.      'Where the case
    raises mixed questions of law and fact, we employ a "degree-of-
    deference continuum," providing "non-deferential plenary review
    for law-dominated questions" and "deferential review for fact-
    dominated questions."'"   Johnson v. Bos. Pub. Schs., 
    906 F.3d 183
    ,
    191 (1st Cir. 2018) (internal citation omitted) (quoting Doe v.
    Cape Elizabeth Sch. Dist., 
    832 F.3d 69
    , 76 (1st Cir. 2016)).      In
    an IDEA case such as this one, we do not employ the typical
    presumptions that accompany summary judgment motions.      Sebastian
    M., 685 F.3d at 85.
    A.
    Falmouth first contends that the District Court erred in
    concluding that John had been denied a FAPE during the time periods
    in question because the District Court based that conclusion on
    the finding that SPIRE does not "address" orthographic processing.
    Falmouth contends that the record compels the conclusion that SPIRE
    does   "specifically   address[]    . . .   orthographic   processing
    issues."   For that reason, Falmouth contends that the District
    Court wrongly concluded that none of the IEPs that were either
    implemented or proposed during the time periods in question was
    - 20 -
    "reasonably calculated" to ensure that John would receive a FAPE,
    Endrew F., 
    137 S. Ct. at 999
    .     And so, Falmouth contends, for this
    reason alone the District Court's ruling that Falmouth denied John
    a FAPE during this time cannot stand.
    But, the District Court did not base the ruling that
    Falmouth denied John a FAPE during the periods at issue on the
    mistaken finding about SPIRE that Falmouth attributes to it.
    Rather, we understand the District Court to have concluded only
    that the preponderance of the evidence supported the hearing
    officer's   conclusion    that   none   of   the       IEPs   at   issue   were
    "reasonably calculated," 
    id.,
     to ensure that John would receive a
    FAPE, because none used Seeing Stars or a similar program and so
    none was "specially designed," 
    id.,
     to address John's specific
    orthographic processing deficit, given both what the record showed
    about the acuity of that deficit and the way that Seeing Stars
    would be "specially designed" to address it while SPIRE would not
    be. Thus, this aspect of Falmouth's challenge fails for the simple
    reason that it takes aim at a supposedly absolute finding about
    the limits on the type of instruction that SPIRE could provide
    that the District Court did not make.
    Falmouth   appears   to   advance      a    related    contention,
    however.    Here, Falmouth argues that the District Court erred in
    ruling that Falmouth denied John a FAPE during the time in question
    because it erred in assessing whether an IEP that relied on Seeing
    - 21 -
    Stars would be "reasonably calculated" to ensure that John would
    make appropriate progress relative to whether an IEP that relied
    on SPIRE would be.          We see no merit to this contention either.
    Falmouth does not dispute that, as the District Court
    pointed out, the record contains an evaluation from Lisa Melnick
    and Barbara Murphy of Aucocisco that specifically recommended
    using      Seeing    Stars    programming     to   address    John's    specific
    "orthographic        processing    deficits."4         Nonetheless,     Falmouth
    contends, the District Court still erred in ruling based on that
    evidence      that   John    had   been   denied   a   FAPE   because    of   the
    contradictory testimony that Falmouth asserts is in the record.
    Here, Falmouth points solely to the testimony from the expert whom
    Falmouth proposed to hire to consult with its own teacher for the
    delivery of Seeing Stars to John under the proposed January 2019
    IEP.       But, the testimony from that expert, Ann Binder, does not
    demonstrate that the District Court's ruling must be overturned.
    The record does show that Binder testified "that SPIRE
    . . . specifically addresses both orthographic processing issues
    We understand Murphy, Melnick, and Binder to have each
    4
    testified based on both their personal knowledge of the case and
    in an expert capacity. The parties, hearing officer, and District
    Court appear to have proceeded on the assumption that the expert
    knowledge to which these witnesses testified was knowable to
    Falmouth at all relevant times.       No party challenges this
    assumption, so we adopt the same premise.
    - 22 -
    and   phonological    processing   issues."5     But,      as   we    have    just
    explained,     the   District   Court   did    not    dispute        that    SPIRE
    "address[es]    orthographic    processing."         So,   this      portion    of
    Binder's testimony does not aid Falmouth's argument on appeal, as
    nothing in it purports to assess SPIRE's ability to address John's
    unique needs relative to Seeing Stars, given the acuity of his
    orthographic processing deficit.
    Moreover, the other portion of Binder's testimony to
    which Falmouth directs our attention also is of no assistance to
    Falmouth.    That portion is the one in which Binder claimed that
    programs like SPIRE address orthography "in a much deeper way than
    Seeing Stars" because "each lesson [of SPIRE] is narrower."                   But,
    in this portion of Binder's testimony, she was clearly discussing
    "orthography," which she later clarified is not the same as
    "orthographic processing" and "is not something on its own that
    can be taught."
    Falmouth has one last related line of challenge.                   It
    appears to be contending that, even if the more record-based
    contentions that we have just considered are not persuasive, our
    decision in Lessard v. Wilton Lyndeborough Cooperative School
    District, 
    518 F.3d 18
     (1st Cir. 2008), and the Supreme Court's
    decision in Endrew F. require us to conclude that the District
    5We note that Seeker, too, claimed that "SPIRE tackles in an
    explicit way the orthographic component."
    - 23 -
    Court erred in ruling that the IEPs at issue were not "reasonably
    calculated," Endrew F., 
    137 S. Ct. at 999
    , to ensure that John
    would receive a FAPE.       But, we disagree.
    Lessard    does    state    that    "state    and   local   education
    agencies" have discretion to "choose among competing pedagogical
    methodologies."     
    518 F.3d at 28
    .           But, Lessard also recognizes
    that courts "are entrusted with ascertaining the adequacy of an
    IEP's educational components," 
    id. at 29
    , and "adequacy" includes,
    as the Supreme Court made clear in Endrew F., whether "[t]he
    instruction offered [is] 'specially designed' to meet a child's
    'unique needs' through an 'individualized education program,'"
    Endrew F., 137 S. Ct at 999 (emphases in original) (quoting 
    20 U.S.C. § 1401
    (14), (29)).        And, the District Court, as we have
    explained,   applied   just    that    standard    in    assessing    whether,
    notwithstanding the IEPs that Falmouth proposed, John was denied
    a FAPE.   Thus, at least given the limited arguments that Falmouth
    makes about the problems with the District Court's assessment of
    the record, we see no basis for concluding that the District Court
    failed to adhere to Lessard or Endrew F. in ruling as it did.
    B.
    We next turn to Falmouth's contention that the District
    Court ignored the Supreme Court's command that reviewing courts
    must determine "[t]he adequacy of a given IEP" in light of "the
    unique circumstance of the child for whom it was created."              Endrew
    - 24 -
    F., 
    137 S. Ct. at 1001
    .      Here, Falmouth argues that the District
    Court erred with respect to its assessment of all the IEPs at
    issue, because it "ignored . . . clear evidence that John was going
    to progress at best slowly under any reading program, instead
    finding FAPE violations based on John's slow growth."                 It further
    contends in this regard that the District Court "failed to account
    for   the   unique   circumstance    that    John    was   a   slow    learner."
    Accordingly, Falmouth contends, the District Court's ruling that
    John was denied a FAPE must be overturned.
    In pressing this line of argument on appeal, Falmouth
    does not engage in any detailed analysis of the District Court's
    treatment of any of the IEPs before us.             But, even if we were to
    conclude that Falmouth's failure in that regard does not amount to
    a waiver of the argument for lack of development, see United States
    v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990), a review of the District
    Court's opinion shows that the District Court did account for the
    fact that John was "a slow learner" -- or, more precisely, that
    John had orthographic and phonological processing deficits -- in
    its analysis of each of the relevant IEPs.
    The District Court began its analysis of the challenged
    IEPs by noting that John was "a complex child with ADHD and
    dyslexia."     The District Court then concluded, consistent with
    Endrew F., that an IEP that was reasonably calculated to enable
    John to make progress had to address the reasons that John might
    - 25 -
    learn more slowly than his peers -- namely, his orthographic
    processing deficit.         See 
    137 S. Ct. at 1001
     (holding that an IEP
    must be "reasonably calculated to enable a child to make progress
    appropriate in light of the child's circumstances," and refusing
    to find that "an educational program providing 'merely more than
    de minimis progress'" met that standard).              And, the District Court
    concluded that each of the IEPs Falmouth developed during this
    time period was inadequate on that score.6             The District Court thus
    did,       contrary   to   Falmouth's    contention,    purport   to   root     its
    findings on a consideration of John's "unique circumstances," 
    id.,
    which the District Court supportably determined to be that John
    would face challenges learning to read because of his orthographic
    and phonological processing deficits.
    C.
    Falmouth    also   contends     that   the   District   Court,    by
    approvingly citing the slow gains that John made at Aucocisco while
    not doing the same with respect to his slow gains at Falmouth,
    only "selectively relied on [John's] unique circumstances."                   But,
    the District Court found that John's progress at Aucocisco was
    still greater than his progress at Falmouth over a much longer
    time, and Falmouth does not develop an argument that the District
    Court clearly erred in so finding.               Thus, there is no basis for
    We again note that the District Court did not address the
    6
    November 2019 IEP and the parties make no argument based on it.
    - 26 -
    concluding that the District Court acted selectively in ruling the
    way that it did.
    D.
    Falmouth next urges us to adopt a Fourth Circuit rule
    that "parents will have to offer expert testimony to show that [a]
    proposed IEP is inadequate."          See Weast v. Schaffer ex rel.
    Schaffer, 
    377 F.3d 449
    , 456 (4th Cir. 2004). Falmouth argues that,
    if we were to do so, we would have to overturn the District Court's
    ruling,   because   the   Does   "provided   no    testimony   against   the
    appropriateness of the Falmouth IEPs, and no testimony that John
    should have made more gains than he actually did under those
    Falmouth IEPs."
    But, the Does provided testimony from Melnick and Murphy
    that John had a serious orthographic processing deficit, that SPIRE
    was not a program whose use made an IEP specially designed to meet
    John's unique needs in consequence of his having a deficit of that
    kind, and that a program (Seeing Stars) did exist that would have
    resulted in an IEP that was designed to do so if that program had
    been employed.    Moreover, Falmouth does not argue that Melnick and
    Murphy were not qualified to so testify.          Thus, the District Court
    did not err even under the framework for analysis set forth in
    Weast that Falmouth urges us to adopt.
    Insofar as Falmouth may be understood also to be arguing
    that, in light of Weast, we should hold that the Does were required
    - 27 -
    to   put    forward   experts   who    specifically   labeled   the   IEPs
    inadequate, rather than experts who merely testified to facts based
    on which the District Court could supportably conclude the IEPs
    were inadequate, Falmouth provides no reason for us to do so.
    Weast does not itself provide support for such a holding because
    Weast does not impose any such requirement, see 
    377 F.3d at
    456-
    57, and, other than invoking Weast, Falmouth make no argument for
    our imposing that requirement here.
    E.
    Falmouth's final challenge that applies to the District
    Court's ruling in favor of the Does that implicates the District
    Court's ruling as to the whole time-span in question -- and thus
    the District Court's assessment of each of the IEPs at issue --
    concerns the LRE requirement.         As we noted at the outset, that
    requirement     "embod[ies]     a   'preference'   for   'mainstreaming'
    students with disabilities in 'the regular classrooms of a public
    school system.'"      C.D., 924 F.3d at 625 (quoting Rowley, 
    458 U.S. at 202-03
    ).
    The District Court found that, under the IEPs at issue,
    John would have spent between 53% and 59% of his time in mainstream
    settings.     It then compared that amount of time that John would
    have spent in mainstream settings under those IEPs to the amount
    of time that John would have spent in such settings under the Does'
    plan to have John split his days between Aucocisco and Falmouth.
    - 28 -
    In undertaking that comparison, the District Court found
    that John would have spent less time in mainstream settings under
    the Does' plan.    But, the District Court went on to find that the
    difference   "appears   insignificant   on   the   record   presented,
    particularly when weighed against the clear need for educational
    improvement."     The District Court thus concluded that, "having
    given due consideration to [the] IDEA's LRE mandate, . . . the
    IEPs Falmouth developed in January 2018 and fall of 2019 failed to
    provide John a FAPE."
    Falmouth contends that the District Court misapplied the
    LRE requirement in so ruling in part because, in finding that John
    was denied a FAPE during the time span in question, the District
    Court failed to "include an analysis of the benefits for John of
    time in mainstream settings [] regardless of any comparison with
    a private arrangement" in its "assessment of Falmouth's . . . IEP."
    Thus, Falmouth argues, the District Court erred in ruling that
    none of the IEPs that Falmouth proposed during the relevant time
    period was "reasonably calculated," Endrew F., 
    137 S. Ct. at 999
    ,
    to ensure that John would receive a FAPE.
    Falmouth is right that, in determining whether the IEPs
    that Falmouth proposed during this time were reasonably calculated
    to ensure that John would receive a FAPE, "the benefits to be
    gained from mainstreaming must be weighed against the educational
    improvements that could be attained in a more restrictive (that
    - 29 -
    is, non-mainstream) environment," C.D., 924 F.3d at 631.             But, the
    District Court did not rule otherwise.          Rather, it considered the
    "difference in LRE time" between Falmouth's IEPs and the Does'
    plan and determined that the "difference in LRE time" between them
    "appears insignificant on the record presented, particularly when
    weighed against the clear need for educational improvement."
    Falmouth next contends that the District Court erred in
    applying the LRE requirement for a different reason.                    Here,
    Falmouth contends that any assessment of whether the IEPs at issue
    were "reasonably calculated" to provide John a FAPE had to be made
    by comparing the amount of mainstream instruction that they would
    provide to the full-time, specialized instruction that John would
    receive at Aucocisco. And, Falmouth asserts, if the District Court
    had employed that comparison, it would have been required to
    determine     that   the   LRE    requirement   precluded      the   negative
    assessment of the IEPs that the District Court made, because John
    received no mainstream instruction at Aucocisco.
    But, as Falmouth acknowledges, the District Court did
    not purport to base the determination that John was denied a FAPE
    on a comparison of any of the IEPs and John's receipt of full-time
    instruction     at   Aucocisco.      The    District   Court    based   that
    determination instead solely on a comparison between each of the
    IEPs and John receiving instruction partly at Falmouth and partly
    at Aucocisco.
    - 30 -
    Falmouth    does go on to argue that even though the
    District Court purported to make that comparison, it was not
    permitted to do so.    Here, Falmouth contends that, given the Does'
    full-time placement of John at Aucocisco and the remedial order by
    the hearing officer and the District Court's affirmance of it, the
    District Court had no choice but to determine whether John had
    been denied a FAPE by assessing the adequacy of the relevant IEPs
    based on a comparison between the type of part-mainstream, part-
    specialized instruction that John would receive under them and the
    full-time specialized instruction at Aucocisco.       And, Falmouth
    then contends, such a comparison could not result in finding that
    the IEPs were inadequate, given the LRE requirement.
    But, the premise that the District Court had to make the
    kind of comparison Falmouth asserted was required does not hold
    up.   And, that is so whether we focus on the fact that the Does
    eventually placed John full-time at Aucocisco or the remedial
    order.
    Local educational agencies in implementing IEPs must
    "evaluat[e] . . . marginal benefits and costs" of placements along
    "a continuum of possible educational environments."       C.D., 924
    F.3d at 631 (internal quotation marks omitted) (quoting Roland M.,
    
    910 F.2d at 992-93
    ).    And, over the course of the two periods that
    are the subject of this appeal, John was placed at Aucocisco for
    both half days and full days.       Falmouth develops no argument,
    - 31 -
    though, as to why the District Court was required to focus on one
    part of the "continuum" concerning his placement at Aucocisco (the
    full-time    part)    rather   than    another      (the   part-time   part)    in
    determining whether the preponderance of the evidence supported
    the hearing officer's conclusion that John was denied a FAPE
    notwithstanding the IEPs that Falmouth developed.               Thus, we do not
    see how the fact of that full-time placement suffices to show that
    this aspect of Falmouth's challenge has merit.
    That leaves to address, then, only the question of
    whether the hearing officer's remedial order in and of itself
    demonstrates that the District Court had no choice in assessing
    whether     the   preponderance       of     the    evidence    supported      the
    determination that the IEPs were not "reasonably calculated" to
    provide John with a FAPE but to compare the instruction that John
    would   receive      under   those    IEPs     to   his    receiving   full-time
    instruction at Aucocisco. But, the fact that a remedy for Falmouth
    having denied John a FAPE may require Falmouth to cover the costs
    of tuition for his full-time instruction at Aucocisco in no way
    suggests that the denial of the FAPE itself depends on the IEPs
    offering instruction that was inadequate only when compared to the
    instruction John would have received from attending that private
    school full-time.       Cf. Florence Cnty., 
    510 U.S. at 15-16
     ("[O]nce
    a court holds that the public placement violated IDEA, it is
    authorized to 'grant such relief as the court determines is
    - 32 -
    appropriate.'" (quoting 
    20 U.S.C. § 1415
    (e)(2))).                    Thus, this
    contention lacks merit, too.
    III.
    Falmouth does have some fallback contentions.                  Here,
    Falmouth challenges the District Court's ruling only insofar as it
    implicates the District Court's assessment of certain of the IEPs
    that   Falmouth   developed   for    John    during    the    two    periods   in
    question.     We thus turn now to these narrow-gauged contentions,
    which, as we will explain, also lack merit.
    A.
    Falmouth first takes aim at the District Court's ruling
    that the January 2018 IEP was not "reasonably calculated to enable
    [John]   to    make   progress      appropriate       in     light    of   [his]
    circumstances," Endrew F., 
    137 S. Ct. at 999
    .                Falmouth contends
    that the District Court erred in so ruling because it relied,
    impermissibly, on information that could not have been known to
    the IEP team at the time that it was developing the January 2018
    IEP because that information concerned the lack of progress that
    John made in reading only after that IEP was in place.               See Roland
    M., 
    910 F.2d at 992
     ("[A]ctions of school systems cannot . . . be
    judged exclusively in hindsight.             An IEP is a snapshot, not a
    retrospective.").     We do not agree, however, with Falmouth's
    characterization of the District Court's ruling.
    - 33 -
    The District Court noted that, at the time that the
    January 2018 IEP was developed, "[d]espite then being in second
    grade,      John's    reading    and    writing       skills    were    still    at   a
    kindergarten level" (emphasis added).                 The District Court further
    noted, again by relying only on information that was available
    prior    to   the     development      of    that    IEP,   that    John's    "special
    education teacher recognized that he had an orthographic deficit
    and described it as his 'biggest challenge.'"                      And, the District
    Court observed that, despite this information being available as
    of   that     point    in   time,     Falmouth      nonetheless      "proposed    only
    incremental increases in the amount of specialized instruction
    John     should      receive    and    did     not    further      evaluate     John's
    orthographic issues, or reconsider the type of specialized reading
    instruction John might need."               Indeed, the District Court found --
    again, based on only the information that predated the IEP itself
    -- that Falmouth "essentially abandoned the preexisting measurable
    reading goal when John failed to reach it."
    Moreover, the District Court determined that, given
    those findings, "the preponderance of the evidence supports a
    finding that the IEP Falmouth developed for John in early 2018
    failed to provide programming that would allow John to make more
    than de minimis progress on basic reading and writing skills over
    the following year." And, in so ruling, the District Court pointed
    - 34 -
    to no contrary evidence in the record, seemingly because it did
    not identify any.
    Falmouth is right that the District Court did reference
    John's progress under the January 2018 IEP in the course of
    rendering this ruling.          But, we do not share Falmouth's view that
    the District Court relied on that post-IEP-development information
    in reaching the conclusion that it did.            Considered in the context
    of the District Court's analysis as a whole, we understand the
    District        Court's    reference      to     that   post-IEP-development
    information       merely   to   have    been    intended   to   reinforce   its
    independent ruling that, based solely on the information available
    to the IEP team prior to the IEP'S development, a preponderance of
    the evidence favored the Does' position over Falmouth's with
    respect to whether that specific IEP provided John a FAPE.
    B.
    Falmouth next focuses on the District Court's ruling
    that the January 2019 was not reasonably calculated to provide
    John a FAPE.       Here, Falmouth appears to contend that the District
    Court incorrectly applied the FAPE standard to the facts before it
    with respect to this negative assessment of the adequacy of this
    IEP.7       Once again, we are not persuaded.
    We note that Falmouth groups this argument under a heading
    7
    of its brief that suggests it contends the District Court made the
    same error Falmouth claimed it made with respect to the January
    2018 IEP by basing the FAPE determination for these IEPs on
    - 35 -
    The District Court concluded that the preponderance of
    the evidence supported the hearing officer's conclusion that the
    January 2019 IEP "fell short," and it agreed with the hearing
    officer that, on this record, the plan was "too little, too late,"
    because      Falmouth's       "plan    for   implementing      [Seeing   Stars]
    programming, including utilizing a teacher, Shar Mahoney, who was
    not certified in LMB and lacked recent experience using LMB, was,
    at   best,   a    work   in   progress."        Falmouth   contends   that    this
    conclusion was improper because the record requires us to conclude
    that, by agreeing "to try the LMB/Seeing Stars reading methodology"
    with implementation "oversee[n]" by "an outside literacy expert -
    - Ann Binder," while "increas[ing] even further the amount of
    literacy instruction" "on top of a host of other important,
    supportive services," Falmouth made "a reasonable calculation of
    how to provide John with meaningful benefits."
    To   support     this    contention,   Falmouth    points   to    the
    evidence in the record that it argues shows that Binder "has
    extensive literacy experience and is certified as an 'educational
    consultant' by the State of Maine."              It further asserts that the
    outcomes rather than on what was "objectively reasonable . . . at
    the time the IEP was promulgated," Roland M., 
    910 F.2d at 992
    .
    But, the specific arguments that Falmouth makes clearly do not
    posit that the District Court committed the legal error suggested
    by that heading with respect to the January 2019 and September
    2019 IEPs. We address the arguments on their own terms and not on
    the terms suggested by the brief heading.
    - 36 -
    record shows that Mahoney, whom Binder would have overseen in
    providing     Seeing       Stars    programming,       is     herself    "a     certified
    teacher with many years of experience, who had gone through the
    training      for    LMB    services."          Falmouth       also     critiques        the
    credentials      and    experience        of   the    leadership      and       tutors    at
    Aucocisco.
    But, Falmouth faces an uphill climb in pressing this
    challenge.          The District Court impliedly found that Binder's
    involvement in delivering Seeing Stars programming to John would
    not change its conclusion with respect to whether an IEP that used
    Seeing   Stars       programming      delivered      by     Mahoney     was   reasonably
    calculated     to      enable      John   to   make       progress.        We    apply     a
    "deferential [standard of] review for" "mixed questions of law and
    fact" that are "fact-dominated."               Cape Elizabeth, 832 F.3d at 76.
    Thus,    we   cannot     see    how   there    is     merit    to   this      ground     for
    overturning the District Court's ruling in favor of the Does
    insofar as it is based on the determination concerning the adequacy
    of this IEP, given what the record shows in the relevant respects
    and the "due weight" that the District Court owed the hearing
    officer's determination, G.D., 27 F.4th at 6.
    Binder's testimony demonstrated that she was dismissive
    towards and relatively unfamiliar with the program that she was
    hired to oversee.          Binder's testimony also indicated that, despite
    Falmouth's awareness of the seriousness of John's orthographic
    - 37 -
    processing deficit, Falmouth did not communicate to Binder when it
    proposed to hire her that orthographic processing was a challenge
    for John, let alone that it was his "biggest challenge."                      Indeed,
    the    record     shows,     Binder        planned    to   help    Mahoney     stress
    phonological       processing        and     phonemic      awareness     in    John's
    programming, rather than orthographic processing.
    Thus, we see no basis for overturning the District
    Court's "too little, too late" assessment on this record.                      As we
    have explained, the record provides support for finding both that
    John had a serious orthographic processing deficit and that Seeing
    Stars was specially designed to address it in a way that SPIRE was
    not.       And,   Falmouth     does    not     contest     the    District    Court's
    determination that the preponderance of the evidence supported the
    hearing    officer's       finding    that     that   Mahoney     was   not   herself
    equipped to adequately deliver Seeing Stars programming to John
    without assistance.8         We therefore reject Falmouth's challenge to
    the District Court's ruling insofar as that challenge focuses
    narrowly on the District Court's asserted error in assessing the
    adequacy of the January 2019 IEP.
    Falmouth does note that Mahoney "is a certified teacher with
    8
    many years of experience, who had gone through the training for
    LMB services." But, Falmouth accepts that Mahoney's "experience
    delivering the [Seeing Stars] program may have been limited," and
    raises this point solely in service of comparing Mahoney to the
    instructors at Aucocisco. And, Falmouth develops no argument that
    a person with only "limited" experience with Seeing Stars was
    equipped to deliver such programming to John.
    - 38 -
    C.
    Falmouth's     final      fallback   contention     concerns      the
    District Court's assessment, in accord with the hearing officer's
    determination, that the September 2019 IEP "was not 'reasonably
    calculated to confer a meaningful educational benefit' to John"
    (quoting Johnson, 906 F.3d at 194) because it did not provide
    "specialized instruction [that] would use LMB programs" such as
    Seeing Stars.    Falmouth contends to us, as it contended below,
    that it was justified, with respect to this IEP, in abandoning its
    proposal to use Seeing Stars because John was making slow progress
    at Aucocisco and because Falmouth offered instead to provide
    "multisensory    synthetic    phonics      instruction"     along   with    an
    additional hour per week of reading instruction.             On that basis,
    Falmouth concludes that the District Court erred, at least in this
    respect, in applying the standard for determining whether a FAPE
    has been denied to a child to the facts of this case.
    But,    as    we   have    explained,   our     review    of     this
    determination by the District Court is deferential due to its fact-
    dominated nature.      See Cape Elizabeth, 832 F.3d at 76.          And, the
    District Court, which in turn was required to give "due weight" to
    the hearing officer's determination, found that the preponderance
    of the evidence supported the hearing officer's conclusion that
    John was denied a FAPE by this IEP because John needed programming
    that would more explicitly target his orthographic processing
    - 39 -
    deficits than SPIRE did due to the acuity of that deficit.               Thus,
    it is problematic that Falmouth points to no evidence in the record
    that shows that "multisensory synthetic phonics instruction" would
    accomplish that task in a way that its prior SPIRE instruction had
    not, especially given testimony that SPIRE itself included such
    instruction.    Accordingly, this challenge, too, fails.
    IV.
    Falmouth     alternatively        contends   that,   even    if   the
    District Court did not err with regard to its ruling that John was
    denied a FAPE during the periods of time in question, the District
    Court erred in upholding the hearing officer's order that Falmouth
    must reimburse the Does for John's tuition at Aucocisco.               Here, as
    well, we disagree.
    A    court   may   "order   school    authorities    to     reimburse
    parents for their expenditures on private special education for a
    child if the court ultimately determines that such placement,
    rather than a proposed IEP, is proper under the [IDEA]."                Mr. I.
    ex rel. L.I. v. Me. Sch. Admin. Dist. No. 55, 
    480 F.3d 1
    , 23 (1st
    Cir. 2007) (quoting Sch. Comm. v. Dep't of Educ., 
    471 U.S. 359
    ,
    369 (1985)).     A proper placement under the IDEA is one that
    provides "'some element of the special education services' missing
    from the public alternative" so that the placement is "reasonably
    calculated to enable the child to receive educational benefit."
    Id. at 25 (emphasis omitted) (quoting Berger v. Medina City Sch.
    - 40 -
    Dist., 
    348 F.3d 513
    , 523 (6th Cir. 2003)).                   We review this
    determination "as a mixed question of fact and law."                Id. at 23.
    Falmouth    argues     that    Aucocisco     was    not    a    proper
    placement because it lacked any mainstreaming, "an essential and
    beneficial piece of programming for John."                 But, the issue of
    whether a parent's unilateral placement of their child at a private
    program is proper for purposes of determining the remedy for a
    denial of a FAPE is "a different issue, and one viewed more
    favorably to the parent, than the question whether                    [such a]
    placement was required in order to provide a free appropriate
    education to" the child.      Rome Sch. Comm. v. Mrs. B., 
    247 F.3d 29
    ,
    33 n.5 (1st Cir. 2001).       A parent's unilateral private placement
    may be "proper under [the] IDEA" even if a placement there would
    not meet all of the requirements that school districts face in
    providing a FAPE.    Florence Cnty., 
    510 U.S. at 13-14
    .           Thus,    "[a]n
    appropriate private placement is not disqualified because it is a
    more restrictive environment than that of the public placement."
    Warren G. ex rel. Tom G. v. Cumberland Cnty. Sch. Dist., 
    190 F.3d 80
    , 84 (3d Cir. 1999).       And, in arguing that that rule should not
    apply   here,   Falmouth     points     only    to   its     contention      that
    mainstreaming   was    "an     essential       and   beneficial      piece     of
    programming for John."       But, the LRE mandate itself reflects that
    Congress has recognized "the desirability of mainstreaming" for
    children receiving services under the IDEA, Roland M., 910 F.2d at
    - 41 -
    993.   And, nonetheless, the IDEA allows for reimbursements for
    private placements in appropriate environments, even when those
    environments      are   more    restrictive     than       what   school    districts
    propose.     See Warren G., 
    190 F.3d at 84
    .
    To the extent that Falmouth is challenging whether the
    District Court erred in assessing that Aucocisco was a "proper"
    placement based on whether it provided ""'some element of the
    special education services' missing from the public alternative,"
    with a "nexus between the special education required and the
    special education provided" at the private placement, Mr. I., 
    480 F.3d at 25
        (quoting     Berger,   
    348 F.3d at 523
    ),   we    disagree.
    Falmouth does assert that the record shows that Aucocisco was not
    a   proper       placement     because    "many       of     [John's]      day-to-day
    instructors at Aucocisco are poorly trained, and have far less
    educational experience than John's Falmouth instructors."                         The
    record evidence, however, suffices for us to defer under our
    standard of review for mixed questions of fact and law to the
    District Court's "fact-dominated," Cape Elizabeth, 832 F.3d at 76-
    77, ruling that the record supportably showed that the teachers at
    Aucocisco were adequately trained and supervised by that school's
    leadership, which was experienced in delivering Seeing Stars, and
    thus   could      deliver    instruction       with    the    requisite      "nexus."
    Moreover, the hearing officer supportably found that John made
    progress at Aucocisco, and the District Court agreed that it was
    - 42 -
    greater progress than he had made in the two prior years at
    Falmouth.
    Finally, Falmouth argues that "the private program has
    been ineffective at addressing [John's] significant attentional
    difficulties."     But, it identifies no portion of the record that
    could    support   this   assertion,    and   it   does    not   explain   how
    Falmouth's own program is any more successful.            Nor does Falmouth
    explain how this assertion bears on the relevant inquiry about the
    proper remedy under the IDEA for the denial of a FAPE.               We thus
    consider this contention to be one "adverted to in a perfunctory
    manner, unaccompanied by some effort at developed argumentation,"
    and, so, we "deem[] [it] waived."        Zannino, 
    895 F.2d at 17
    .
    V.
    We next turn to the Does' cross-appeal from the District
    Court's dismissal under Federal Rule of Civil Procedure 12(b)(6)
    of the Does' counterclaims against Falmouth. To resolve the cross-
    appeal, we must accept the facts alleged in the Does' complaint as
    true and draw all reasonable inferences in the Does' favor.            Legal
    Sea Foods, LLC v. Strathmore Ins. Co., 
    36 F.4th 29
    , 34 (1st Cir.
    2022).     To prevail, the Does need show only that their complaint
    includes    "enough   factual   detail   to   make   the    asserted   claim
    'plausible on its face.'"       Cardigan Mtn. Sch. v. N.H. Ins. Co.,
    
    787 F.3d 82
    , 84 (1st Cir. 2015) (quoting Ashcroft v. Iqbal, 556
    - 43 -
    U.S. 662, 678 (2009)).      Our review is de novo.         Frith v. Whole
    Foods Mkt., Inc., 
    38 F.4th 263
    , 269 (1st Cir. 2022).
    A.
    The District Court held that "the only adverse action
    plausibly alleged in the counterclaims is the denial and/or delay
    of John's rights under the IDEA" to a FAPE and that "the Does'
    counterclaims fail to plausibly allege that retaliatory animus or
    disability-based animus is what caused or motivated the decisions
    regarding John's IEPs."      The District Court thus ruled that the
    Does' ADA and RHA claims could not survive the motion to dismiss
    as they were, at bottom, only "disguised IDEA" claims.          As to the
    § 1983 count, moreover, the District Court found that the same
    rationale   applied   and   alternatively   found   that    Kucinkas   was
    entitled to qualified immunity because he had not violated a
    clearly established First Amendment right held by the Does.
    B.
    The Does argue that "allegations of 'disability-based
    animus' or 'retaliatory animus' are sufficient to differentiate
    Section 504/ADA discrimination and retaliation claims from an
    underlying IDEA action, even if the adverse action is the same."
    They then assert that their complaint, "viewed holistically,"
    makes their allegations of animus as to both the ADA and Section
    504 claims plausible based on "the cumulative effect of the factual
    allegations contained in the complaint" (quoting A.G. ex rel.
    - 44 -
    Maddox v. Elsevier, Inc., 
    732 F.3d 77
    , 82 (1st Cir. 2013)).   We do
    not agree.
    1.
    With respect to the Does' challenge to the District
    Court's order dismissing their ADA and RHA claims insofar as they
    are based on retaliation, all of the Does' allegations concern
    conduct that Falmouth undertook before the Does requested a Section
    504 plan.    And, while the Does allege that Falmouth continued its
    conduct after the Does requested that plan, the complaint does not
    allege that Falmouth in fact responded to the request in any way
    besides developing and implementing a Section 504 plan for John.
    Nor do the Does develop an argument that they engaged in any other
    conduct that is protected under the ADA and RHA that did not occur
    after the allegedly adverse actions by Falmouth.         Thus, the
    District Court did not err in finding that the Does had not
    adequately alleged retaliation.
    2.
    We turn next to the Does' claim that they adequately
    pleaded discriminatory animus with respect to their ADA and RHA
    claims.   The District Court acknowledged that claims under the ADA
    or RHA can survive even when they have some overlap with a claim
    under the IDEA.     Nonetheless, the District Court held that the
    allegations in the Does' complaint were insufficient to plead the
    "disability-based animus" that the Does agree must have been
    - 45 -
    pleaded for their claims to go forward.     The District Court not
    only concluded "that the requisite animus was not plead in the
    counterclaim," but also that "nothing in the record . . . would
    support an inference of retaliatory animus or disability-based
    animus as motivating the denial of a FAPE."    It concluded instead
    that "Falmouth's IEPs for John reflect a failure on the part of
    Falmouth to meet the standards required by the IDEA, but not an
    attempt to discriminate against John or retaliate for his parents'
    advocacy on his behalf."
    In response, the Does merely recite a laundry list of
    allegations, "the cumulative effect" of which is, they contend, "a
    pattern of conduct" and "a pattern of deliberate indifference to
    John's plight due to the nature of his disability."     See Ocasio-
    Hernández v. Fortuño-Burset, 
    640 F.3d 1
    , 14-15 (1st Cir. 2011)
    ("No single allegation" in a complaint "need lead to the conclusion
    . . . of some necessary     element, provided that, in sum, the
    allegations of the complaint make the claim as a whole at least
    plausible.").   They do not cite any analogous case, and they do
    not explain how the District Court erred.     Cf. A.G., 732 F.3d at
    80-82 (rejecting a claim that a complaint could survive a motion
    to dismiss in light of "the cumulative effect of the factual
    allegations" where the complaint was found to be "speculative" in
    crucial respects).   In light of the conclusory manner in which the
    Does have chosen to press their challenge to this aspect of the
    - 46 -
    District Court's ruling, we reject their challenge and affirm the
    District Court's dismissal of their claims under the ADA and
    Section 504 insofar as they allege discriminatory animus.
    C.
    We come, then, to the Does' challenge to the District
    Court's   dismissal      of       their   counterclaim      under    § 1983   against
    Kucinkas.     The Does contend that their complaint plausibly alleges
    that Kucinkas's conduct violated their First Amendment rights
    because he acted with retaliatory animus, and the District Court
    thus erred in dismissing this count.                    The Does further contend
    that   the    District     Court     erred       by   alternatively    finding    that
    Kucinkas was entitled to qualified immunity.                        They argue that
    Kucinkas's      violated      a    "clearly      established"   right     under    the
    federal constitution, specifically "[t]he right of parents to be
    free from retaliation for exercising their First Amendment right
    to advocate for their child's rights."
    We need not address qualified immunity because the Does'
    complaint does not plausibly allege a claim against Kucinkas under
    § 1983.      For their claim to survive a motion to dismiss, the Does'
    complaint must allege that "(1) [they] engaged in constitutionally
    protected conduct, (2) [they were] subjected to an adverse action
    by [Kucinkas], and (3) the protected conduct was a substantial or
    motivating factor in the adverse action."                  D.B. ex rel. Elizabeth
    B. v. Esposito, 
    675 F.3d 26
    , 43 (1st Cir. 2012).                    In this context,
    - 47 -
    we understand the third prong of this test to essentially be an
    inquiry into whether the Does have alleged that Kucinkas had
    "retaliatory animus."    See Maloy v. Ballori-Lage, 
    744 F.3d 250
    ,
    253 (1st Cir. 2014). Even assuming the Does have plausibly alleged
    facts that satisfy the first two prongs of that test, the District
    Court was correct to dismiss their counterclaim under § 1983
    because they have failed to allege the requisite retaliatory
    animus.
    In support of their argument otherwise, the Does again
    point to "'the cumulative effect of the factual allegations'
    contained in the[ir] complaint," A.G., 732 F.3d at 82 (quoting
    Ocasio-Hernández, 640 F.3d at 14), and argue that those allegations
    -- including allegations that Kucinkas "engag[ed] in intentional
    misrepresentation designed to chill their advocacy, willfully
    conceal[ed]   critical   information    about   the   nature   of   John's
    learning disability, . . . den[ied] the existence of specialized
    reading instruction to target his disability," and "attempt[ed] to
    interfere with John's receipt of the instruction he needed from
    Aucocisco, while maintaining mainstream contact with the Falmouth
    Elementary School" -- plausibly allege retaliatory animus.            They
    also note the "temporal proximity" "between the protected conduct"
    and what they deem to be "the retaliatory response."
    The Does do not contend, however, that any inadequate or
    unreasonable response to a request that parents make in the course
    - 48 -
    of a dispute over whether their child is being given the services
    needed to ensure that the child is receiving a FAPE may fairly be
    characterized as "retaliation."      And, a review of the allegations
    in the complaint that are asserted to plausibly show that Falmouth
    engaged in retaliatory conduct here, within the meaning of the
    First Amendment, shows, at best, only one that possibly could
    ground such a claim.      That allegation concerns Kucinkas's alleged
    "attempt[] to interfere with John's receipt of the instruction he
    needed from Aucocisco" by, when the Does decided to send John to
    Aucocisco each afternoon in January 2019, "insist[ing] that John
    continue   to   receive   specialized     instruction   from   Falmouth's
    teachers during the portion of the day he spent at Falmouth
    Elementary School" rather than allowing him to spend his mornings
    solely in his mainstream classroom.
    But, the Does concede in their briefing to us that they
    revoked consent for John to receive services under the IDEA only
    after Kucinkas made that decision.         Thus, we do not see how the
    Does can argue that they have plausibly alleged that Kucinkas's
    alleged "interfere[nce]" was anything other than his attempt to
    ensure that Falmouth was fulfilling its duties under the IDEA,
    given that John was eligible for services under the IDEA, the Does
    had consented to John receiving such services, and -- as Falmouth
    was not, at the time, paying for John's tuition at Aucocisco --
    specialized education in the morning outside of his mainstream
    - 49 -
    classroom was the only service Falmouth was providing John to
    ensure he received a FAPE.    For, there is nothing in the complaint
    that would provide a basis for concluding otherwise.       Cf. Carreras
    v. Sajo, García & Partners, 
    596 F.3d 25
    , 38 (1st Cir. 2010) (noting
    that, in the employment context, "suspicions raised by temporal
    proximity 'can be authoritatively dispelled . . . by an employer's
    convincing account of the legitimate reasons for the firing'"
    (ellipses   in   original)   (quoting   Holloway   v.   Thompson   Island
    Outward Bound Educ. Ctr., 
    275 F. App'x 25
    , 27 (1st Cir. 2008))).
