    OPINION
    CALLAHAN, Circuit Judge:
    Anthony Tommasetti (“Tommasetti”) filed an application
    for Social Security benefits claiming that he was unable to
    work because of lower back pain and diabetes mellitus. After
    an initial denial of that application, and following what the
    district court characterized as an “administrative odyssey,” the
    Social Security Appeals Council remanded Tommasetti’s
    claim to a new Administrative Law Judge (“ALJ”) to conduct
    a de novo hearing. At that hearing, the ALJ took testimony
    from a medical expert, a vocational expert (“VE”), and Tom-
    masetti. After largely rejecting the opinion of one of Tomma-
    setti’s treating physicians and finding Tommasetti’s testimony
    not credible, the ALJ concluded, based almost entirely on the
    VE’s testimony, that Tommasetti could perform his past
    work. Alternatively, the ALJ found that Tommasetti could
    perform other work in the national economy and local econ-
    omy. The Appeals Council declined jurisdiction over Tomma-
    setti’s appeal, and the district court affirmed the ALJ’s
    decision as supported by substantial evidence.
    We hold that the ALJ provided “clear and convincing” rea-
    sons for rejecting Tommasetti’s testimony as not credible. See
    Smolen v. Chater, 
    80 F.3d 1273
    , 1283-84 (9th Cir. 1996). We
    further conclude that the ALJ provided “specific and legiti-
    mate” reasons based on substantial evidence for her partial
    rejection of the treating physician’s opinion. See Lester v.
    Chater, 
    81 F.3d 821
    , 830-31 (9th Cir. 1995). Finally, we hold
    8832                      TOMMASETTI v. ASTRUE
    that although the ALJ erred in finding that Tommasetti could
    perform past work, see Johnson v. Shalala, 
    60 F.3d 1428
    ,
    1434-35 (9th Cir. 1995), this error was harmless because the
    ALJ properly decided that Tommasetti could perform other
    work in the economy. See Robbins v. Soc. Sec. Admin., 
    466 F.3d 880
    , 885 (9th Cir. 2006). Accordingly, we affirm the dis-
    trict court’s decision.
    I.   Background
    A.     Tommasetti’s Relevant Personal and Medical History
    Tommasetti was 53 years old on the alleged date of onset
    of his medical conditions at issue here, and he was 59 years
    old when his disability insurance expired in December 1999.
    Tommasetti attended college in Italy, has training in electron-
    ics, and previously worked as an electronics technician and
    TV repair person. He was involved in a car accident in April
    1994 and was in pain until October 1994. Later that year he
    fell off a ladder while working. He was involved in subse-
    quent car accidents in 1999 and 2000.
    While Tommasetti saw several physicians, at issue on
    appeal is Dr. Andrea Nachenberg’s reports based on her inter-
    mittent treatment of Tommasetti.1 Dr. Nachenberg first saw
    Tommasetti in March 1995, at which time she noted his
    claims of back pain and inability to stay in one position for
    more than ten minutes. Upon conducting a physical exam she
    noted “no evidence of weakness” and “minimal tenderness”
    on palpation. She diagnosed a “probable lumbosacral strain
    superimposed on osteoarthritis of the lumbar spine.” She saw
    him again in July 1996 for right shoulder and right knee pain,
    and in October 1996 for lower back pain. An x-ray of his back
    revealed spurring and narrowing of the L4-5 and L5-S1 inter-
    spaces. Tommasetti again saw Dr. Nachenberg in March 1997
    and November 1997 about lower back pain. In December
    1
    Dr. Nachenberg did not testify at the administrative hearing.
    TOMMASETTI v. ASTRUE                  8833
    1997, Dr. Nachenberg wrote a letter that summarized Tomma-
    setti’s medical history and concluded that she did “not expect
    him to recover significantly at this time.” Dr. Nachenberg
    next saw Tommasetti in September 1998 and completed a
    “Musculoskeletal System Residual Functional Capacity Ques-
    tionnaire” (“Questionnaire”). She stated that Tommasetti
    could sit continuously for ten minutes, and for up to four
    hours in an eight-hour workday; stand continuously for thirty
    minutes, and for up to two hours in an eight-hour workday;
    required use of a lumbosacral corset; and could at most occa-
    sionally lift ten pounds.
    B.   Hearing Testimony
    Tommasetti testified at the hearing before the ALJ regard-
    ing his lower back pain and diabetes. He testified that he
    could not stand, walk, climb ladders, or work; but that he
    could have a job where he was on his feet for no more than
    two hours a day, without ladder-climbing. He claimed that at
    the time in question he could lift at most a few pounds. He
    also stated that he stopped taking prescribed medicine in 1995
    or 1996 due to dizziness, and he could not recall if a doctor
    had prescribed the walking cane he intermittently used. He
    further testified that he had made no attempts to work and that
    he supported himself with $97,000 in savings. Contrary to
    previous representations, Tommasetti testified that diabetes
    was not a disabling problem and that medication properly
    controlled it.
    At the hearing, the ALJ took testimony from Dr. Wiseman,
    an agency medical expert who testified based on his review
    of Tommasetti’s medical records. The ALJ found Dr. Wise-
    man’s testimony to be “somewhat equivocal.” Although Dr.
    Wiseman opined that Tommasetti had elected to limit himself
    based on self-chosen limitations, he refused to definitively
    assess Tommasetti’s condition. Instead, he merely “accepted”
    what Dr. Nachenberg stated. He did not, however, explicitly
    endorse Dr. Nachenberg’s assessment.
    8834                   TOMMASETTI v. ASTRUE
    The VE testified regarding Tommasetti’s ability to perform
    his prior work and other work in the national economy and
    local economy. The VE noted that Tommasetti previously
    worked in electronics assembly and TV repair. The VE
    responded to hypothetical questions based on the following
    residual functioning capacity: capable of lifting up to ten
    pounds, standing or walking for six hours in an eight-hour
    workday (in two-hour increments), and sitting for six hours in
    an eight-hour workday. Regarding prior work as an electron-
    ics assembler, the VE opined that Tommasetti could not per-
    form that work as he had previously performed it, but
    concluded without much elaboration that he could perform it
    as it is “typically performed.” The VE also testified that Tom-
    masetti could perform work in the national economy as a
    semiconductor assembler, for which there were 100,000 jobs
    nationally and 9,000 jobs regionally.
    II.    Standards of Review
    We review the district court’s order affirming the ALJ’s
    denial of social security benefits de novo, Burch v. Barnhart,
    
    400 F.3d 676
    , 679 (9th Cir. 2005), and will disturb the denial
    of benefits only if the decision “contains legal error or is not
    supported by substantial evidence.” Orn v. Astrue, 
    495 F.3d 625
    , 630 (9th Cir. 2007) (citation omitted). Substantial evi-
    dence is “ ‘such relevant evidence as a reasonable mind might
    accept as adequate to support a conclusion.’ ” 
    Id. (quoting Burch,
    400 F.3d at 679). The “evidence must be more than a
    mere scintilla but not necessarily a preponderance.” Connett
    v. Barnhart, 
    340 F.3d 871
    , 873 (9th Cir. 2003) (citation omit-
    ted). The ALJ’s findings will be upheld “if supported by
    inferences reasonably drawn from the record . . . .” Batson v.
    Comm’r of Soc. Sec. Admin., 
    359 F.3d 1190
    , 1193 (9th Cir.
    2004). The court will uphold the ALJ’s conclusion when the
    evidence is susceptible to more than one rational interpreta-
    tion. 
    Burch, 400 F.3d at 679
    ; 
    Batson, 359 F.3d at 1193
    .
    Finally, the court will not reverse an ALJ’s decision for harm-
    less error, which exists when it is clear from the record that
    TOMMASETTI v. ASTRUE                  8835
    “the ALJ’s error was ‘inconsequential to the ultimate nondisa-
    bility determination.’ ” 
    Robbins, 466 F.3d at 885
    (quoting
    Stout v. Comm’r, Soc. Sec. Admin., 
    454 F.3d 1050
    , 1055-56
    (9th Cir. 2006)).
    III.   Discussion
    The ALJ used the required five-step sequential framework
    to determine whether Tommasetti was disabled. See 20 C.F.R.
    § 404.1520; see also 
    Burch, 400 F.3d at 679
    . At step one, the
    ALJ found that Tommasetti had not engaged in substantial
    gainful activity during the relevant period. At step two, the
    ALJ concluded that Tommasetti “satisfied the threshold or de
    minimus step of having a severe impairment” by reason of his
    lumbosacral condition and diabetes mellitus. At step three, the
    ALJ found that Tommasetti’s back condition and diabetes did
    not meet or equal one of the listed impairments in the regula-
    tions. At step four, based on the residual functional capacity
    determination and the VE’s testimony, the ALJ concluded
    that Tommasetti was able to perform past relevant work as an
    electronics assembler. However, acknowledging “confusion
    in the analysis of past relevant work” and her hesitation “to
    play expert,” the ALJ made an alternative step five finding
    that, assuming Tommasetti could not perform past work, he
    could still perform other work in the national or local econ-
    omy as a semiconductor assembler.
    A.   Adverse Credibility Determination
    Tommasetti argues that the ALJ’s adverse credibility find-
    ing is not supported by the record. In order to find Tommaset-
    ti’s testimony regarding the severity of his pain and
    impairments unreliable, the ALJ was required to make “a
    credibility determination with findings sufficiently specific to
    permit the court to conclude that the ALJ did not arbitrarily
    discredit claimant’s testimony.” Thomas v. Barnhart, 
    278 F.3d 947
    , 958 (9th Cir. 2002). The ALJ conducts a two-step
    analysis to assess subjective testimony where, under step one,
    8836                 TOMMASETTI v. ASTRUE
    the claimant “must produce objective medical evidence of an
    underlying impairment” or impairments that could reasonably
    be expected to produce some degree of symptom. 
    Smolen, 80 F.3d at 1281-82
    . If the claimant meets this threshold and there
    is no affirmative evidence of malingering, “the ALJ can reject
    the claimant’s testimony about the severity of her symptoms
    only by offering specific, clear and convincing reasons for
    doing so.” 
    Id. at 1281,
    1283-84. The ALJ may consider many
    factors in weighing a claimant’s credibility, including “(1)
    ordinary techniques of credibility evaluation, such as the
    claimant’s reputation for lying, prior inconsistent statements
    concerning the symptoms, and other testimony by the claim-
    ant that appears less than candid; (2) unexplained or inade-
    quately explained failure to seek treatment or to follow a
    prescribed course of treatment; and (3) the claimant’s daily
    activities.” 
    Id. at 1284;
    see 
    Orn, 495 F.3d at 637-39
    . If the
    ALJ’s finding is supported by substantial evidence, the court
    “may not engage in second-guessing.” 
    Thomas, 278 F.3d at 959
    .
    [1] Here, the ALJ gave Tommasetti “the benefit of the
    doubt” that he had a verifiable impairment and, therefore, the
    ALJ was required to provide clear and convincing reasons in
    support of her adverse credibility finding. The ALJ provided
    several permissible reasons. First, she inferred that Tomma-
    setti’s pain was not as all-disabling as he reported in light of
    the fact that he did not seek an aggressive treatment program
    and did not seek an alternative or more-tailored treatment pro-
    gram after he stopped taking an effective medication due to
    mild side effects. This is a permissible inference. See Parra
    v. Astrue, 
    481 F.3d 742
    , 750-51 (9th Cir. 2007) (stating that
    “evidence of ‘conservative treatment’ is sufficient to discount
    a claimant’s testimony regarding severity of an impairment”);
    see also Meanel v. Apfel, 
    172 F.3d 1111
    , 1114 (9th Cir. 1999)
    (rejecting subjective pain complaints where petitioner’s
    “claim that she experienced pain approaching the highest
    level imaginable was inconsistent with the ‘minimal, conser-
    TOMMASETTI v. ASTRUE                         8837
    vative treatment’ that she received”).2 The record reflects that
    Tommasetti responded favorably to conservative treatment
    including physical therapy and the use of anti-inflammatory
    medication, a transcutaneous electrical nerve stimulation unit,
    and a lumbosacral corset. Such a response to conservative
    treatment undermines Tommasetti’s reports regarding the dis-
    abling nature of his pain.
    [2] Second, the ALJ cited that Tommasetti was a “vague
    witness” with respect to the alleged period of disability and
    pain symptoms. The ALJ may rely on ordinary techniques of
    credibility evaluation. 
    Smolen, 80 F.3d at 1284
    . The record
    supports the ALJ’s determinations that on questioning Tom-
    masetti “was not clear or certain insofar as his self-assessed
    work capabilities,” and that he was not “a precise judge of his
    own capacities.” She further commented that Tommasetti had
    made no attempts to perform sedentary work and had pro-
    vided only a vague explanation as to why: “Because I cooked.
    I would feel good.” The ALJ also noted that Tommasetti
    could not recall whether the cane he occasionally used was
    prescribed by a doctor.
    [3] Third, the ALJ pointed to Tommasetti’s testimony that
    his severe diabetes was not a “disabling problem,” was con-
    trolled by medication, and was not the reason he stopped
    working. This testimony undermines Tommasetti’s prior
    claims that his diabetes was among his disabling conditions.
    See 
    Smolen, 80 F.3d at 1284
    .
    2
    Tommasetti testified that his doctors suggested back surgery, but that
    he did not want to risk the procedure. Although not expressly relied on by
    the ALJ, the district court contrasted Tommasetti’s reluctance to undergo
    back surgery to possibly end his debilitating pain with his willingness to
    risk an invasive elective surgery that would correct a largely cosmetic uro-
    logical condition. Because the ALJ did not rely on this reason in support
    of her credibility determination, we may not rely upon it here. See Con-
    
    nett, 340 F.3d at 874
    (“We are constrained to review the reasons the ALJ
    asserts.”).
    8838                    TOMMASETTI v. ASTRUE
    [4] Fourth, the ALJ stated that regarding the period in ques-
    tion Tommasetti “may not have been motivated to work due
    to his then large financial reserve.” Although some might not
    consider $97,000 to be a large financial reserve, we cannot
    say that the ALJ’s inference regarding Tommasetti’s motiva-
    tion to work based on this savings was unreasonable. See
    Sample v. Schweiker, 
    694 F.2d 639
    , 642 (9th Cir. 1982) (stat-
    ing that in reaching findings the ALJ “is entitled to draw
    inferences logically flowing from the evidence”).
    [5] Finally, the ALJ doubted Tommasetti’s testimony about
    the extent of his pain and limitations based on his ability to
    travel to Venezuela for an extended time to care for an ailing
    sister. The ALJ could properly infer from this fact that Tom-
    masetti was not as physically limited as he purported to be. Id.3
    [6] The ALJ’s reasons for discounting Tommasetti’s testi-
    mony are supported by substantial evidence in the record.
    Accordingly, we will not disturb the ALJ’s adverse credibility
    finding.
    B.     Rejection of Dr. Nachenberg’s Opinion
    [7] Tommasetti next argues that the ALJ improperly dis-
    counted the opinion of his treating physician, Dr. Andrea
    Nachenberg, regarding Tommasetti’s physical limitations. Dr.
    Nachenberg completed the Questionnaire, in which she
    opined that Tommasetti could sit continuously for ten min-
    utes, sit for four hours in an eight-hour workday, stand contin-
    uously for thirty minutes, stand/walk for two hours in an
    eight-hour workday, required an ability to sit and stand at
    will, needed unscheduled breaks, and could at most occasion-
    ally lift ten pounds. The ALJ rejected Dr. Nachenberg’s opin-
    ion only to the limited extent that it ruled out Tommasetti’s
    “capacity for sedentary work” during the period in question.
    3
    Although Tommasetti raises the fact that he had to see a physician for
    exacerbation of his back pain while in Venezuela, the physician only con-
    sidered Tommasetti “unable to do strong physical work.”
    TOMMASETTI v. ASTRUE                   8839
    The ALJ must consider all medical opinion evidence. 20
    C.F.R. § 404.1527(b). Although the ALJ is not bound by an
    expert medical opinion on the ultimate question of disability,
    she must provide “specific and legitimate” reasons for reject-
    ing the opinion of a treating physician. 
    Lester, 81 F.3d at 830
    -
    31. “The ALJ can meet this burden by setting out a detailed
    and thorough summary of the facts and conflicting clinical
    evidence, stating [her] interpretation thereof, and making
    findings.” Magallanes v. Bowen, 
    881 F.2d 747
    , 751 (9th Cir.
    1989) (citation omitted).
    [8] The ALJ complied with Magallanes and provided spe-
    cific and legitimate reasons for rejecting Dr. Nachenberg’s
    opinion that are supported by the entire record. The ALJ
    stated that Dr. Nachenberg’s assessment was essentially a “re-
    hashing of claimant’s own statements,” and was therefore
    undermined by the ALJ’s finding that Tommasetti was not
    credible. An ALJ may reject a treating physician’s opinion if
    it is based “to a large extent” on a claimant’s self-reports that
    have been properly discounted as incredible. Morgan v.
    Comm’r Soc. Sec. Admin., 
    169 F.3d 595
    , 602 (9th Cir. 1999)
    (citing Fair v. Bowen, 
    885 F.2d 597
    , 605 (9th Cir. 1989)). A
    review of Dr. Nachenberg’s records reveals that they largely
    reflect Tommasetti’s reports of pain, with little independent
    analysis or diagnosis. Additionally, Dr. Wiseman, the consult-
    ing medical expert, testified that Dr. Nachenberg’s Question-
    naire primarily reflected Tommasetti’s self-assessment and
    subjective willingness to work. Thus, the ALJ’s adverse credi-
    bility determination supports the limited rejection of Dr. Nac-
    henberg’s opinion because it was primarily based on
    Tommasetti’s subjective comments concerning his condition.
    [9] Further, after discussing Tommasetti’s medical history
    and treatments in detail, the ALJ found that Dr. Nachenberg’s
    Questionnaire responses were inconsistent with the medical
    records. For example, the ALJ stated that the ultimate conclu-
    sions from Dr. Nachenberg’s Questionnaire regarding the
    extent of Tommasetti’s ability to stand and sit and his need
    8840                TOMMASETTI v. ASTRUE
    for breaks “did not mesh with her objective data or history.”
    Indeed, Dr. Nachenberg’s medical records do not provide sup-
    port for the limitations set out in the Questionnaire. The
    incongruity between Dr. Nachenberg’s Questionnaire
    responses and her medical records provides an additional spe-
    cific and legitimate reason for rejecting Dr. Nachenberg’s
    opinion of Tommasetti’s limitations.
    [10] Tommasetti contends that Dr. Wiseman’s “deferral” to
    Dr. Nachenberg’s assessment weighs against the ALJ’s rejec-
    tion of Dr. Nachenberg’s opinion. Although Dr. Wiseman
    “accepted” Dr. Nachenberg’s opinion, Dr. Wiseman simulta-
    neously concluded that Dr. Nachenberg’s opinion was based
    on Tommasetti’s self-reporting and expressed doubts as to
    Tommasetti’s limitations. He also refused to provide a defi-
    nite opinion of Tommasetti’s condition or limitations. Dr.
    Wiseman’s testimony, although equivocal, did not amount to
    a concurrence in Dr. Nachenberg’s opinion but only indicated
    that he accepted her opinion because she was a qualified phy-
    sician. In any event, the ALJ is the final arbiter with respect
    to resolving ambiguities in the medical evidence. See
    Andrews v. Shalala, 
    53 F.3d 1035
    , 1039-40 (9th Cir. 1995)
    (“The ALJ is responsible for determining credibility, resolv-
    ing conflicts in medical testimony, and for resolving ambigui-
    ties.”) (citing 
    Magallanes, 881 F.2d at 750
    ). On this record,
    the ALJ reasonably rejected Dr. Nachenberg’s opinion to the
    extent that it precluded Tommasetti from performing seden-
    tary work.
    C.     Tommasetti’s Ability to Perform Past Work and
    Other Work
    [11] Tommasetti further argues that the ALJ committed
    error at step four by finding that he could have returned to
    past work as an electronics assembler. The ALJ determined
    that Tommasetti’s physical impairment limited him to “seden-
    tary work,” with a maximum lifting capacity of ten pounds.
    At step four, the ALJ and VE agreed that, based on the elec-
    TOMMASETTI v. ASTRUE                    8841
    tronics assembler job classification in the Dictionary of Occu-
    pational Titles (“DOT”), Tommasetti could not perform
    electronics assembly work as he actually performed it because
    it would require him to lift more than ten pounds. However,
    the VE testified that electronics assembly work is performed
    in a variety of ways in the national economy. The ALJ
    deferred to the VE’s assessment, stating that “regardless of
    the differences in demands in the position as performed in the
    national economy, it would not ordinarily require that the
    individual perform activities requiring a greater residual func-
    tional capacity” than that of Tommasetti.
    [12] This assessment is contrary to the ALJ’s determination
    that Tommasetti could only perform “sedentary” work
    because the DOT lists the “electronics assembler” position as
    requiring “light” exertion. Dictionary of Occupational Titles
    § 726.684-018 (4th ed. 1991); see 20 C.F.R. § 404.1567(a),
    (b). The DOT creates a rebuttable presumption as to the job
    classification. 
    Johnson, 60 F.3d at 1435
    . To deviate from the
    DOT classification, an ALJ “may rely on expert testimony
    which contradicts the DOT, but only insofar as the record
    contains persuasive evidence to support the deviation.” 
    Id. Here, the
    ALJ offered her own speculative explanation to
    rebut the DOT’s presumptive exertion requirement, comment-
    ing that the reason for the light exertion label is that the posi-
    tion “may require some pushing or pulling of arm controls.”
    She concluded that this requirement should not elevate the job
    classification from sedentary to light. The ALJ also deferred
    to the VE’s personal knowledge and experience as supersed-
    ing the DOT to the extent that the light exertion label was
    related to any standing/walking requirements.
    [13] The ALJ’s determination that Tommasetti could return
    to his work as an electronics assembler is not supported by the
    record. Instead of persuasive evidence in the record, the ALJ
    relied on her own speculation and the VE’s brief and indefi-
    nite testimony. Id.; Soc. Sec. Ruling 00-4p (Dec. 4, 2000)
    (stating that “[t]he adjudicator must resolve the conflict by
    8842                     TOMMASETTI v. ASTRUE
    determining if the explanation given by the VE or [vocational
    specialist] is reasonable and provides a basis for relying on
    the VE or [vocational specialist] testimony rather than on the
    DOT information”). The ALJ did not identify what aspect of
    the VE’s experience warranted deviation from the DOT, and
    did not point to any evidence in the record other than the VE’s
    sparse testimony for the deviation. Therefore, the ALJ’s step
    four finding was erroneous.
    [14] Although the ALJ’s step four determination constitutes
    error, it is harmless error in light of the ALJ’s alternative find-
    ing at step five. At step five, the ALJ concluded that, assum-
    ing Tommasetti could not perform past work, he could still
    perform other work in the national and local economies that
    existed in significant numbers. 20 C.F.R. §§ 404.1520(a)
    (4)(v), 404.1560(c); 
    Robbins, 466 F.3d at 885
    (holding that
    error that is inconsequential to the ultimate nondisability
    determination is harmless error). The ALJ, relying on the
    VE’s testimony, found that Tommasetti could work as a semi-
    conductor assembler, which is a sedentary, semi-skilled posi-
    tion offering 100,000 positions nationally and 9,000
    regionally. See Dictionary of Occupational Titles § 726.684-
    034. The VE testified that Tommasetti’s prior skills as an
    electronics assembler transferred to the “very closely related”
    semiconductor assembler job because both positions involve
    similar assembler tools, assembler products, and sub-
    assembly components, and the semiconductor assembler posi-
    tion simply involves smaller items.
    [15] The ALJ also found that the VE’s testimony aug-
    mented Rule 201.07 of the Medical Vocational Guidelines
    (the “grids”), 20 C.F.R. Part 404, Subpart P, Appendix 2,4
    4
    We summarized the role of the grids, in the evaluation of a disability
    claim in Lounsburry v. Barnhart, 
    468 F.3d 1111
    , 1114-15 (9th Cir. 2006):
    The grids are applied at the fifth step of the analysis under 20
    C.F.R. § 404.1520, and present, in table form, a short-hand
    TOMMASETTI v. ASTRUE                         8843
    which provides an alternate basis for finding that Tommasetti
    was not disabled. Pursuant to Rule 201.07, a claimant of
    advanced age who is limited to sedentary work, has a high
    school degree, can perform skilled or semi-skilled work, and
    has transferrable skills is “not disabled.” Rule 201.07 is aug-
    mented by Rule 201.00(f), which states that “[i]n order to find
    transferability of skills to skilled sedentary work for individu-
    als who are of advanced age . . . , there must be very little,
    if any, vocational adjustment required in terms of tools, work
    processes, work settings, or the industry.” Tommasetti meets
    these criteria.
    Tommasetti argues that the ALJ’s step five determination
    is undermined by this court’s decision in Lounsburry v. Barn-
    hart, 
    468 F.3d 1111
    (9th Cir. 2006), which was filed after the
    district court’s decision in this case. In Lounsburry, the claim-
    ant was restricted to performing light work and had transferr-
    able skills. 
    Id. at 1116.
    The court found that Rule 202.07,
    from the grid table governing light exertion, applied and that
    Footnote 2 to Rule 202.07 expressly incorporated language
    from Rule 202.00(c). 
    Id. The result
    of this incorporation was
    that a person of advanced age with a high school degree who
    could do light work could only be found “not disabled” if her
    skills were readily transferable to a “significant range” of
    method for determining the availability and numbers of suitable
    jobs for a claimant. [Tackett v. Apfel, 
    180 F.3d 1094
    , 1101 (9th
    Cir. 1999).] The grids categorize jobs by their physical-exertional
    requirements, and set forth a table for each category. A claim-
    ant’s placement with the appropriate table is determined by
    applying a matrix of four factors identified by Congress—a
    claimant’s age, education, previous work experience, and physi-
    cal ability. For each combination of these factors, they direct a
    finding of either “disabled” or “not disabled” based on the num-
    ber of jobs in the national economy in that category of physical-
    exertional requirements. 
    Id. If a
    claimant is found able to work
    jobs that exist in significant numbers, the claimant is generally
    considered not disabled. Heckler v. Campbell, 
    461 U.S. 458
    , 461
    . . . (1983).
    8844                   TOMMASETTI v. ASTRUE
    semi-skilled or skilled work. 
    Id. at 1116-17.
    The court held
    that one “occupation” did not constitute a “significant range”
    and, because the ALJ had only identified one occupation,
    Lounsburry was “disabled.” 
    Id. at 1117.
    [16] Tommasetti asks the court to extend Lounsburry’s def-
    inition of “significant range,” which pertains to a light work
    analysis under Rule 202.00(c), to his case, which involves a
    sedentary work analysis under Rule 201.07. He asserts that
    applying Lounsburry, the ALJ erred at step five by identifying
    only one occupation to which Tommasetti could adjust, i.e.,
    semiconductor assembler. We do not agree. Lounsburry is
    distinguishable because it involved a different grid rule that
    was based on light exertion (Rule 202.07), whereas this case
    involves a grid rule based on sedentary exertion (Rule
    201.07). A plain reading of Rule 201.07 makes clear that it is
    not augmented by Rule 202.00(c), the specific text which was
    the driving consideration in 
    Lounsburry. 468 F.3d at 1116-17
    .
    Moreover, the grid rules related to sedentary exertion do not
    contain the language of Rule 202.00(c).5 The Social Security
    Administration has promulgated rules that treat jobs requiring
    light exertion and sedentary exertion differently under the
    grids. Tommasetti has not convinced us that we should do
    otherwise. Accordingly, we reject Tommasetti’s attempt to
    graft rules applicable to the light exertion grid onto the seden-
    tary exertion grid. A contrary result would lead to the con-
    fused and arbitrary application of grid rules from one
    exertional category to other exertional categories and might
    well, in effect, defeat the goal of consistency and uniformity
    in decision-making that the particularized grids serve. See
    Soc. Sec. Ruling 83-10 (1983) (stating that the regulations
    were expanded to include Appendix 2 and the grids to “in-
    crease consistency and promote the uniformity with which
    disability determinations are made” at step five).

    Tommasetti’s argument that Rule 201.00(e) is the “same provision” as
    Rule 202.00(c) is not persuasive based on the text of the rules.
    TOMMASETTI v. ASTRUE                 8845
    IV.   Conclusion
    We affirm the district court’s conclusion that substantial
    evidence supports the ALJ’s decision that Tommasetti was
    not disabled and thus not entitled to disability benefits. The
    ALJ provided clear and convincing reasons for rejecting Tom-
    masetti’s testimony as not credible, and she provided specific
    and legitimate reasons for discounting Dr. Nachenberg’s opin-
    ions regarding Tommasetti’s physical limitations and ability
    to perform sedentary work. Finally, although the ALJ erred at
    step four in finding that Tommasetti could perform his past
    work, this error was harmless because the ALJ properly con-
    cluded as an alternative at step five that he could perform
    work in the national and regional economies as a semiconduc-
    tor assembler.
    AFFIRMED.
