    SUMMARY**
    Education Law
    The panel affirmed the district court’s judgment on
    remand in an action brought by a student, by and through his
    parents, under the Individuals with Disabilities Education
    Improvement Act of 2004.
    The student’s school district determined in 2005 that,
    despite his learning disability of auditory processing disorder
    or central auditory processing disorder, the student was not
    eligible for special education services. In 2008, as a result of
    further testing procured by his parents, the school district
    determined that the student did qualify for special education.
    Shortly thereafter, he moved to another school district, which
    also recognized that he qualified for special education.
    The panel held that the student failed to show that the
    school district acted unreasonably in determining in 2005 that
    he did not qualify for special education services under the
    “specific learning disability” category because he lacked the
    required severe discrepancy between his intellectual ability
    and his achievement.
    The Department of Education, as amicus curiae, took the
    position that a central auditory processing disorder is eligible
    for consideration for benefits under the “other health
    impairment” category. The panel held that this position
    merited deference. The panel nonetheless determined that the

    4               E.M. V. PAJARO VALLEY USD
    OPINION
    CALLAHAN, Circuit Judge:
    In 2004, before E.M. entered the fourth grade, he was first
    tested for a learning disability. Through this lengthy
    litigation it has been established that E.M. has an auditory
    processing disorder or a central auditory processing disorder.
    However, in the fall of 2004 and the spring of 2005, E.M.’s
    school district, the Pajaro Valley Unified School District
    (“PVUSD”) tested E.M. and determined that, despite his
    learning disability, E.M. was not eligible for special
    education services. Subsequently, as a result of further
    testing procured by E.M.’s parents, PVUSD determined in
    February 2008 that E.M. did qualify for special education.
    Shortly thereafter, E.M. moved to another school district
    which also recognized that he qualified for special education.
    Meanwhile, E.M. filed an administrative complaint with
    the Special Education Division of the California Office of
    Administrative Hearings. When the Administrative Law
    Judge (“ALJ”) issued a decision in favor of PVUSD, E.M.,
    through his parents (the “Plaintiffs”), filed a complaint in the
    United States District Court for the Northern District of
    California alleging that E.M. had been denied a “Free and
    Appropriate Public Education” as set forth in the Individuals
    with Disabilities Education Improvement Act of 2004
    (“IDEA”). 20 U.S.C. §§ 1400, et seq. The district court
    granted summary judgment in favor of PVUSD, Plaintiffs
    appealed, and we issued an opinion affirming in part,
    reversing in part and remanding. E.M. v. Pajaro Valley
    Unified Sch. Dist., 
    652 F.3d 999
    (9th Cir. 2011). On remand
    the district court again denied Plaintiffs any relief and further
    ruled that E.M.’s central auditory processing disorder could
    E.M. V. PAJARO VALLEY USD                       5
    not be considered an “other health impairment” under the
    applicable federal and state regulations. See 34 C.F.R.
    § 300.7(c)(9) (2005); Cal. Code Regs. Tit. 5, § 3030(f)
    (2005).1
    On this appeal we address three primary issues. First, we
    conclude that Plaintiffs have failed to show that PVUSD
    acted unreasonably in determining in 2005 that E.M. did not
    qualify for special education services under the “specific
    learning disability” category. See 20 U.S.C. § 1403(1)(A).
    Second, we conclude that the Department of Education’s
    position that a central auditory processing disorder is eligible
    for consideration for benefits under the “other health
    impairment” category merits deference.            Finally, we
    determine that Plaintiffs have failed to show that PVUSD
    acted unreasonably in not considering E.M. for benefits under
    the “other health impairment” category in 2005.
    Accordingly, we affirm the denial of relief to Plaintiffs.
    I
    A. PVUSD’s Initial Assessment of E.M.
    E.M. enrolled in PVUSD as a kindergarten student in
    1999. Plaintiffs assert that E.M. struggled at school and that
    PVUSD should have referred him for a special education
    assessment as early as December 2002, pursuant to its “child
    find” obligation. This provision of the IDEA requires school
    districts to identify children with disabilities and to ensure
    1
    Both the federal and state regulations have been subsequently
    amended.
    6                     E.M. V. PAJARO VALLEY USD
    that each child is evaluated and provided appropriate special
    education services.2
    In the summer of 2004, before E.M. entered the fifth
    grade, Plaintiffs had E.M. tested by psychologist Dr. Roz
    Wright, who administered the Weschsler Intelligence Scale
    for Children (3d ed.) and the Woodcock Johnson Tests of
    Achievement-III (“WISC”). Dr. Wright estimated E.M.’s
    intelligence quotient (“IQ”) to be 104, based on the test.
    Plaintiffs then requested that PVUSD evaluate E.M. and
    submitted Dr. Wright’s assessment.
    In October 2004, PVUSD convened a meeting of E.M.’s
    Individualized Education Program (“IEP”) team. In addition
    to Dr. Wright’s assessment, the IEP team considered the
    results of additional tests administered by Leslie Viall,
    PVUSD’s psychologist.
    Ms. Viall, who had more than fifteen years of experience
    administering educational assessments of children, testified
    that she thought the WISC score of 104 was a valid measure
    of E.M.’s intellectual ability. She stated that in October 2004,
    2
    20 U.S.C. § 1412(a)(3)(A) states:
    All children with disabilities residing in the State,
    including children with disabilities who are homeless
    children or are wards of the State and children with
    disabilities attending private schools, regardless of the
    severity of their disabilities, and who are in need of
    special education and related services, are identified,
    located, and evaluated and a practical method is
    developed and implemented to determine which
    children with disabilities are currently receiving needed
    special education and related services.
    E.M. V. PAJARO VALLEY USD                    7
    she had given E.M. the Kaufman Assessment Battery for
    Children test (“K-ABC” test) and that E.M. had obtained a
    higher score of 111. Ms. Viall explained that she
    administered the K-ABC test because the parents’ assessor,
    Dr. Wright, had recently administered the WISC test and that
    re-administering the same test less than four months later
    would have produced an invalid score. When the K-ABC test
    produced a significantly higher score, Ms. Viall administered
    a third intelligence test, the Test of Nonverbal Intelligence
    (“TONI”), on which E.M. scored a 98. Because E.M.’s TONI
    score was consistent with his performance on the WISC,
    rather than the higher score on the K-ABC, Ms. Viall
    determined that 104 was the most reliable measure of E.M.’s
    intellectual ability.
    In 2005, to qualify for special education under the
    “specific learning disability” (sometimes referred to as
    “SLD”) category in California, a child had to meet three
    requirements: (1) “there must be a severe discrepancy
    between intellectual ability and achievement in oral
    expression, listening comprehension, written expression,
    basic reading skills, reading comprehension, mathematics
    calculation, or mathematical reasoning”; (2) “the severe
    discrepancy must be due to a disorder in one or more of the
    basic psychological processes and must not be primarily the
    result of an environmental, cultural, or economic
    disadvantage”; and (3) “the discrepancy cannot be
    ameliorated through other regular or categorical services
    offered within the regular education program.” Cal. Educ.
    Code § 56337 (2005).
    PVUSD determined that E.M. had not demonstrated the
    requisite “severe discrepancy between intellectual ability and
    achievement.” The applicable California regulations defined
    8              E.M. V. PAJARO VALLEY USD
    a severe discrepancy as a difference of at least 22.5 points,
    adjusted by 4 points, between a child’s ability and
    performance. Faced with three scores, 111 on the K-ABC,
    104 on the WISC, and 98 on the TONI, PVUSD opted to use
    the middle score, 104 on the WISC. E.M.’s lowest standard
    score in any academic area was 87 on listening
    comprehension. The discrepancy between 87 and 104 was
    only 17 points, not sufficient to constitute a severe
    discrepancy.
    B. Plaintiffs’ Initial Proceedings Before the
    Administrative Law Judge and the District Court
    When PVUSD denied E.M. special education benefits,
    Plaintiffs filed an administrative complaint with the Special
    Education Division of the California Office of Administrative
    Hearings. A hearing was held, and on May 2006, the ALJ
    issued a final decision denying Plaintiffs any relief.
    Plaintiffs then commenced this action in the United States
    District Court for the Northern District of California. In
    October 2007, the district court denied cross-motions for
    summary judgment and remanded the case to the ALJ. The
    ALJ was asked to “set forth more completely his reasoning as
    to why the WISC test was favored over the K-ABC, as well
    as his approach to evaluating all of the quantitative test data
    in light of the mixed results of that data.”
    Meanwhile, Plaintiffs had E.M. tested by Dr. Cheryl
    Jacques, who estimated his IQ to be 110. PVUSD then
    retested E.M. for eligibility for special education and found
    E.M.’s IQ to be 114. This led PVUSD to determine in
    February 2008 that E.M. was eligible for special education
    benefits. Shortly thereafter, E.M. moved to the Fullerton
    E.M. V. PAJARO VALLEY USD                              9
    Joint Union High School District, which also determined that
    he was eligible for special education services.
    On remand, the ALJ again determined that Plaintiffs were
    not entitled to any relief. Plaintiffs appealed to the district
    court.
    On August 27, 2009, the district court granted PVUSD’s
    motion for summary judgment. In doing so, the court first
    agreed with the ALJ that Ms. Viall was credible and her
    reasoning persuasive.3 The court noted the irony that PVUSD
    relied on the diagnostic score provided by Plaintiffs, while
    Plaintiffs claimed that PVUSD should have used its own K-
    ABC scores. The district court further agreed with the ALJ
    that PVUSD had administered multiple tests to E.M. and had
    used the totality of the results to arrive at its ultimate
    determination of ineligibility.
    3
    The district court noted that Ms. Viall had stated that she felt “the
    WISC is a test of choice and it showed consistency with the TONI, and [I]
    didn’t use the full scale score because of [E.M.’s] bilingual background,
    so it seemed more valid to use the performance score.” The court also
    observed that Ms. Viall had indicated that she thought E.M.’s score on the
    K-ABC was inflated because it was not consistent with the WISC or
    TONI scores, and testified that she “no longer used the K-ABC because
    she had found that the test failed to provide ‘good information for looking
    at student’s processing.’” The court further observed that “Ms. Viall had
    conferred with other educators, who had confirmed the possibility of
    inflated K-ABC scores, and at the time of the due process hearing she
    believed that ‘the WISC is a much more researched and much more
    reliable and valid measure.’” The court discounted Dr. Wright’s
    testimony to a certain extent because she did not observe E.M. in the
    classroom, review his school records, or speak with his teachers, and Dr.
    Wright’s assessment “was intended to serve an entirely different purpose,
    namely a finding of eligibility under the ADA that would be relevant to
    the family’s immigration proceedings.”
    10                 E.M. V. PAJARO VALLEY USD
    The district court further noted that “viewed as a whole,
    the observational and anecdotal evidence describes a student
    who was distracted easily but who also responded to various
    forms of classroom intervention.” It opined that had E.M.
    “been able to complete assignments and homework on a more
    consistent basis, it seems likely that he would have been a
    consistently average to above-average performer.”
    Finally, addressing Plaintiffs’ allegation that PVUSD
    failed to perform assessments with respect to E.M.’s auditory
    processing, hearing and behavior, the district court
    commented that at least one auditory processing test was
    administered by Ms. Viall, and that PVUSD’s resource
    specialist “conducted the Brigance test in both Spanish and
    English as part of the initial assessment, and this test arguably
    addresses auditory processing through a subtest involving
    sentence repetition.”4
    C. Plaintiffs’ Initial Appeal to the Ninth Circuit
    Plaintiffs appealed, and we issued an opinion affirming in
    part and reversing in part. E.M. v. Pajaro Valley Unified Sch.
    Dist., 
    652 F.3d 999
    (9th Cir. 2011). We recognized that
    “school districts have discretion in selecting the diagnostic
    tests they use to determine special education eligibility.” 
    Id. at 1003.
    Noting the different tests used to evaluate E.M., we
    4
    The district court related that “Ms. Viall testified that E.M. did not
    appear to suffer from auditory processing difficulties because he started
    tasks immediately when given oral instructions, and the WISC-III
    assessment had not shown a processing disorder.” She further stated that
    “the fact that E.M. had progressed to an A-level student in certain
    academic areas, as well as his improvement in standardized math skills to
    the basic level, are highly probative of an ability to succeed in the regular
    classroom environment.”
    E.M. V. PAJARO VALLEY USD                      11
    held that a school district, “considering all relevant material
    available on a pupil, must make a reasonable choice between
    valid but conflicting test results in determining whether a
    ‘severe discrepancy’ exists.” 
    Id. at 1004.
    We did not determine whether PVUSD’s choice was
    reasonable because we determined that the district court had
    erred in excluding Dr. Jacques’s 2007 report.5 
    Id. at 1006.
    Accordingly, the district court was instructed on remand to
    consider whether Dr. Jacques’s report, as well as PVUSD’s
    2008 assessment of E.M., were “relevant to the determination
    whether PVUSD met its obligations to E.M.” 
    Id. We then
    held, over a dissent, that Plaintiffs had not
    waived their assertion that the district court should have
    considered whether E.M.’s auditory processing disorder
    qualified him for special education as a child with an “other
    health impairment.” 
    Id. at 1006.
    We remanded the case to
    the district court “for a determination whether, during all
    relevant times, PVUSD met its affirmative obligation to
    locate, evaluate, and identify E.M. as a child with an other
    health impairment or a specific learning disability related to
    his auditory processing disorder.” Id at 1007.
    5
    We explained:
    The district court excluded Dr. Jacques’s report as not
    “necessary to evaluate the ALJ’s determination.” The
    proper inquiry was whether the report was relevant,
    non-cumulative, and otherwise 
    admissible. 652 F.3d at 1006
    .
    12                 E.M. V. PAJARO VALLEY USD
    D. The District Court’s Opinion on Remand
    On remand, the district court read our opinion as holding
    that “E.M. had a ‘disorder in a basic psychological process,’
    specifically, ‘an auditory processing disorder.’” However,
    the court found that we had not reached “the issue of whether
    PVUSD’s choice among test scores was reasonable; rather
    [we] remanded the matter for further consideration of that
    issue.” The district court proceeded to determine whether
    Plaintiffs had shown that there was a “severe discrepancy”
    between E.M.’s intellectual ability and his achievement.
    The district court noted that all agree that E.M.’s lowest
    academic standard score was 87. The court then reviewed the
    three test scores, and concluded that the ALJ’s use of the
    WISC’s score of 104, and the consequential finding that there
    was no severe discrepancy (only 17 points difference), were
    “thorough and careful” and entitled to deference. The court
    further conducted its own de novo review of the evidence in
    the administrative record, and concluded that Plaintiffs had
    not met their burden of showing that it was unreasonable for
    PVUSD to use the WISC test score.
    The district court agreed with the ALJ that the school
    psychologist’s testimony was more persuasive than Dr.
    Wright’s perspective because of her experience
    administrating educational assessments to children and her
    actual knowledge of E.M.6 The court further found that
    6
    The ALJ had reasoned:
    Leslie Viall’s testimony established that the
    performance score on the WISC-III of 104 is the valid
    measure of [E.M.’s] intellectual ability. Ms. Viall is a
    E.M. V. PAJARO VALLEY USD                           13
    neither Dr. Jacques’s report nor the PVUSD’s 2008
    assessment of E.M. altered its determination that PVUSD’s
    2005 assessment of E.M. was not unreasonable.
    Turning to the issue of whether E.M. could qualify for
    special education on the basis of having an “other health
    impairment,” the district court noted that 20 U.S.C.
    § 1401(3)(A)(i) listed nine defined categories such as
    “intellectual disabilities,” “autism,” and “specific learning
    disabilities,” and a tenth category described broadly as “other
    health impairment.” At the time of the PVUSD assessment,
    “other health impairment” (sometimes referred to as “OHI”)
    was defined as follows:
    Other health impairment means having
    limited strength, vitality or alertness to
    environmental stimuli, that results in limited
    credentialed school psychologist with more than 15
    years’ experience administering educational
    assessments to children. She testified that the WISC is
    the most common intelligence quotient test
    administered to children, as well as the best predictor of
    school performance. Ms. Viall administered the K-
    ABC when she assessed [E.M.] in October 2004 only
    because the parents’ assessor, Dr. Wright, had recently
    administered the WISC-III.          If Ms. Viall had
    administered the WISC-III less than four months after
    Dr. Wright’s administration, Ms. Viall would have
    obtained an invalid score. When Ms. Viall obtained a
    significantly higher score on the K-ABC (111), she
    administered another intelligence test, the [TONI,] to
    obtain more information. [E.M.’s] TONI score of 98
    was consistent with [E.M.’s] performance score on the
    WISC-III, not the inflated score on the K-ABC.
    14                 E.M. V. PAJARO VALLEY USD
    alertness with respect to the educational
    environment, that –
    (i) Is due to chronic or acute health problems
    such as asthma, attention deficit disorder or
    attention deficit hyperactivity disorder,
    diabetes, epilepsy, a heart condition,
    hemophilia, lead poisoning, leukemia,
    nephritis, rheumatic fever, and sickle cell
    anemia; and
    (ii) Adversely affects a child’s educational
    performance.
    34 C.F.R. § 300.7(c)(9)).
    Despite Plaintiffs’ contrary assertion, the district court did
    not find any decisions by courts or hearing officers
    specifically holding that auditory processing disorders qualify
    as OHIs. Accordingly, the court approached the question as
    a matter of first impression, using canons of construction.
    The court determined that “specific learning disability” and
    “other health impairment” concerned two different categories
    of impairment.7 The district court, noting that the statute
    7
    The district court explained:
    In the regulations, “specific learning disability” is
    defined to mean “a disorder in one or more of the basic
    psychological processes involved in understanding or
    in using language,” see 34 C.F.R. § 300.7(c)(10)
    (2005); Cal. Code Regs. tit. 5, § 3030(j) (2005),
    provided such disorder results in a “severe discrepancy
    between [the child’s] intellectual ability and
    achievement,” see Cal. Code Regs. tit. 5, § 3030(j)
    E.M. V. PAJARO VALLEY USD                            15
    included a non-exhaustive list, employed the dictionary
    meaning of “other” as “another,” and concluded that because
    a qualifying auditory processing disorder is a “specific
    learning disability,” “it necessarily follows that an auditory
    processing disorder cannot at the same time be an ‘other
    health impairment.’” The court expressed concern that a
    contrary finding would render superfluous the requirement of
    showing severe discrepancy to qualify for benefits under the
    “specific learning disability” category.8
    (2005); see also Cal. Educ. Code § 56337 (2005). A
    “specific learning disability” thus is “specific” to
    disorders adversely affecting the processing of the
    written and/or spoken word. As is set forth in the
    applicable regulations, such processing disorders
    expressly include “auditory processing” disorders. See
    Cal. Code Regs. tit. 5, § 3030(j)(1) (2005).
    As defined in the regulations, an “other health impairment” is a “chronic
    and acute health problem” that “[a]dversely affects a child’s educational
    performance.” See 34 C.F.R. § 300.7(c)(9) (2005); see also Cal. Code
    Regs. tit. 5, § 3030(f) (2005) (providing pupil is entitled to special
    education where pupil has “chronic and acute health problem[ ]” that
    “adversely affects a pupil’s educational performance”).
    8
    The district court reasoned:
    A contrary finding would effectively negate and render
    superfluous the statutory and regulatory provisions that
    a “disorder in a basic psychological process” qualifies
    as a “specific learning disability” only if, as a result of
    such disorder, a “severe discrepancy” exists between
    the child’s intellectual ability and academic
    achievement. See Cal. Educ. Code § 56337 (2005);
    Cal. Code Regs. tit. 5, § 3030(j) (2005); see also Hart
    v. McLucas, 
    535 F.2d 516
    , 519 (9th Cir. 1976) (holding
    “in the construction of administrative regulations, as
    well as statutes, it is presumed that every phrase serves
    16              E.M. V. PAJARO VALLEY USD
    Having concluded that PVUSD had reasonably
    determined that Plaintiffs had failed to show a “severe
    discrepancy” between E.M.’s intellectual ability and
    academic achievement in 2005, and that E.M.’s auditory
    processing disorder could not be an “other health
    impairment,” the district court granted judgment in favor of
    PVUSD. Plaintiffs filed a timely notice of appeal.
    II
    A district court’s compliance with our mandate is
    reviewed de novo. United States v. Paul, 
    561 F.3d 970
    , 973
    (9th Cir. 2009); United States v. Kellington, 
    217 F.3d 1084
    ,
    1092 (9th Cir. 2000). We also review de novo “the district
    court’s decision that the school district complied with the
    IDEA.” K.D. v. Dep’t of Education, 
    665 F.3d 1110
    , 1117
    (9th Cir. 2011); N.B. v. Hellgate Elementary Sch. Dist.,
    
    541 F.3d 1202
    , 1207 (9th Cir. 2008). However, we give “due
    weight to judgments of education policy when reviewing state
    hearings and must take care to not substitute [our] own
    notions of sound educational policy for those of the school
    authorities [we] review.” 
    K.D., 665 F.3d at 1117
    (internal
    a legitimate purpose and, therefore, constructions which
    render regulatory provisions superfluous are to be
    avoided”). If a “specific learning disability” were
    deemed to constitute an “other health impairment” as
    well, a child with a specific learning disability would
    need to show only a generalized “adverse[ ]” effect on
    academic performance. See 34 C.F.R. § 300.7(c)(9)
    (2005). As PVUSD argued at the hearing, and E.M. did
    not dispute, the “adversely affects” standard and the
    “severe discrepancy” standard are different. E.M. fails
    to explain why Congress, for purposes of the IDEA,
    would have intended the same impairment be assessed
    under two tests of differing magnitude.
    E.M. V. PAJARO VALLEY USD                    17
    quotation marks omitted). Although “[t]he extent of
    deference given to the state hearing officer’s determination is
    within our discretion,” “[w]e give deference to the state
    hearing officer’s findings particularly when, as here, they are
    thorough and careful.” Id.; see also Union Sch. Dist. v.
    Smith, 
    15 F.3d 1519
    , 1524 (9th Cir. 1994).
    In K.D., we further reiterated that: (1) we review “the
    district court’s factual determinations for clear error, even
    when based on the administrative record”; (2) a “finding of
    fact is clearly erroneous when the evidence in the record
    supports the finding but the reviewing court is left with a
    definite and firm conviction that a mistake has been
    committed”; and (3) the party “challenging the district court’s
    ruling, bears the burden of proof on 
    appeal.” 665 F.3d at 1117
    (internal quotation marks omitted).
    III
    A. The District Court Complied with Our Mandate
    Initially, we affirm that the district court order is
    consistent with our mandate. Plaintiffs argue that we had
    found that E.M. had a specific learning disability, that we
    held that the district court should apply more of a de novo
    standard of review, and that the ALJ should not have relied
    on the testimony of PVUSD’s psychologist. We held that
    E.M. had alleged an auditory processing disorder, but we did
    not reach the question of whether Plaintiffs had shown that
    E.M. had qualified for special education benefits under the
    “specific learning disability” category. Our opinion did not
    alter the standard of review or make any factual
    determinations as to any witness’s credibility. Rather, we
    remanded for a determination whether “PVUSD met its
    18              E.M. V. PAJARO VALLEY USD
    affirmative obligation to locate, evaluate, and identify E.M.
    as a child with an other health impairment or a specific
    learning disability related to his auditory processing
    disorder.” 
    E.M., 652 F.3d at 1007
    . The district court did this
    in compliance with our mandate.
    B. Plaintiffs Have Not Shown that PVUSD
    Unreasonably Found that E.M. Lacked the Severe
    Discrepancy Between His Achievement and
    Academic Test Scores Then Required to Qualify
    for Benefits Under the “Specific Learning
    Disability” Category
    In Schaffer v. Weast, 
    546 U.S. 49
    , 56–58 (2005), the
    Supreme Court clarified that under the IDEA, the burden of
    persuasion rests with the party seeking relief. Here, all
    appear to agree that E.M.’s achievement score in 2004 was
    87, and that then applicable state regulations required a
    difference of 22.5 points between E.M.’s achievement and
    ability scores. Thus, to prevail on their claims that E.M. was
    entitled to special education benefits under the “specific
    learning disability” category, Plaintiffs have to show that it
    was unreasonable for PVUSD to use any test results other
    than E.M.’s score on the K-ABC test. This they have failed
    to do.
    In challenging PVUSD’s use of the WISC test, Plaintiffs
    argue that: (1) the school psychologist, Ms. Viall testified that
    the K-ABC test was a good cognitive test; (2) although Ms.
    Viall testified that other colleagues thought the scores on the
    K-ABC test can be inflated, she “was never able to identify
    which colleagues and what their credentials were”; and
    (3) Ms. Viall’s belief that E.M.’s score on the K-ABC test
    was high was a product of her unreasonably low expectations.
    E.M. V. PAJARO VALLEY USD                       19
    Plaintiffs assert that at least one authoritative article in a peer
    reviewed journal identified the K-ABC test as the best
    predictor of achievement of all cognitive tests. They also
    submitted a declaration from Dr. Kaufman, who authored
    both portions of the WISC test and the K-ABC test, favoring
    the use of the K-ABC test and noting that it was not
    appropriate to substitute a brief test such as the TONI for
    comprehensive tests such as the K-ABC. In addition, Dr.
    Wright, who administered the WISC test, testified that E.M.
    had been unusually distracted when he took the test.
    Plaintiffs also contend that Dr. Jacques’s report supports
    their positions that: (1) E.M. had a long history of auditory
    processing disorder symptoms; (2) PVUSD was on notice that
    E.M. had a learning disability; and (3) E.M. had a long
    history of school failures. Plaintiffs point to Dr. Jacques’s
    statement that she found it “puzzling” that the district did not
    find E.M. eligible for special education services in 2005.
    Plaintiffs have shown that PVUSD could have used
    E.M.’s K-ABC score, but they have not shown that PVUSD
    acted unreasonably in using his WISC score. The record
    shows that Dr. Wright gave E.M. the WISC test in the
    summer of 2004 and that E.M. scored a 104 on that test.
    Plaintiffs then asked PVUSD to test E.M. for a learning
    disability. PVUSD did so. The school psychologist
    administered the K-ABC test because re-administering the
    WISC test would not have produced a reliable score. E.M.
    scored 111 on the K-ABC test. Ms. Viall, noting the disparity
    between the test scores and having concerns both about K-
    ABC test scores in general and E.M.’s score in particular,
    administered a third test. On the TONI test, E.M. scored 98.
    PVUSD considered all three test results and then decided to
    20                 E.M. V. PAJARO VALLEY USD
    use the middle score, the one submitted by Plaintiffs. This
    course of action has the indicia of reasonableness.
    Plaintiffs’ evidence and arguments do not undermine the
    reasonableness of PVUSD’s decision. Plaintiffs presented
    evidence such as Dr. Kaufman’s declaration praising the K-
    ABC test, but not evidence that the other two tests were not
    well-respected tests for cognitive ability or that it was
    unreasonable to average test scores from different tests.
    Moreover, none of the later developed information – Dr.
    Jacques’s report, the 2008 assessment, or the later
    assessments by E.M.’s new school district – bear on
    PVUSD’s 2005 determination because they do not undermine
    E.M.’s test scores on the WISC and TONI. The later
    developed evidence does indicate that E.M. had a learning
    disability in 2004, but PVUSD did not deny that he had a
    disability. Rather, it denied relief because there was not a
    22.5 point discrepancy between E.M.’s tested ability and
    performance. Subsequently, when E.M. was retested and
    reevaluated, PVUSD in 2008 determined that he was eligible
    for special educational benefits.9
    9
    Dr. Jacques’s report included the following comment:
    Why has the gap widened between [E.M.’s] measured
    IQ scores and his achievement scores? The current
    testing used the most recent versions and normative
    updates, and because of the proposed population
    advances in knowledge, the updated tests are harder.
    Probably more importantly for [E.M.], the increased
    academic load in middle school and the cumulative
    experiences of failure have contributed to a widening
    gap in his intelligence and his achievement levels.
    E.M. V. PAJARO VALLEY USD                    21
    In 
    Schaffer, 546 U.S. at 62
    , the Supreme Court held that
    the party challenging the district court’s ruling bears the
    burden of proof on appeal, and in 
    K.D., 665 F.3d at 1117
    , we
    held that we review the district court’s factual determinations
    for clear error. In E.M., we reiterated that “school districts
    have discretion in selecting the diagnostic tests they use to
    determine special education 
    eligibility.” 652 F.3d at 1003
    .
    Applying these standards, we conclude that the record,
    developed over at least seven years, does not show that
    PVUSD unreasonably denied E.M. special education benefits
    in 2005 under the “specific learning disability” category.
    Accordingly, the district court’s determination of this issue
    must be affirmed.
    C. We Defer to the Department of Education’s
    Position that a Child With a Disability May Be
    Eligible for Special Educational Benefits Under
    More Than One Category
    Although we held in 
    E.M., 652 F.3d at 1007
    , that
    Plaintiffs had not waived their contention that E.M.’s auditory
    processing disorder could qualify him for special education
    as a child with an “other health impairment,” the merits of
    this contention had not been previously addressed. In
    addressing the contention in the first instance, the district
    court did not have the benefit of the perspective of the
    Department of Education (“DOE”). On appeal, the DOE has
    participated as an amicus curiae. Thus, in reviewing the
    district court’s reading of 20 U.S.C. § 1401(3)(A)(i), we have
    22                E.M. V. PAJARO VALLEY USD
    the benefit of the views of the agency charged by Congress
    with administering the IDEA. See 20 U.S.C. §§ 1406, 1416.10
    In 1991, the DOE issued a Joint Policy Memorandum that
    explained that a child with attention deficit disorder or
    attention deficit hyperactivity disorder might qualify for
    special education benefits under one of three categories of the
    IDEA’s definition of “child with a disability” – “other health
    impairment,” “specific learning disability,” or “serious
    emotional disturbance.” 18 IDELR 116 (Sept. 16, 1991). In
    1994, the DOE’s Office of Special Education Programs
    issued a letter explaining that a child with chronic fatigue
    syndrome could qualify for special education under the “other
    health impairment” category or under another category if the
    child met the criteria for that category. Letter to Fazio,
    21 IDELR 572 (Apr. 26, 1994). The DOE asserts that while
    these documents do not address auditory processing
    disorders, they reflect the Secretary’s position that a
    particular condition may qualify for benefits under more than
    one of the IDEA categories.
    The DOE asserts that its interpretation of a “child with a
    disability” is consistent with the history and purpose of the
    IDEA. Congress first enacted the IDEA in 1970 “to reverse
    this history of neglect” of disabled children in the United
    States. 
    Schaffer, 546 U.S. at 52
    . Congress subsequently
    expanded the definition of children with disabilities to
    10
    Section 1406 authorizes the Secretary of Education to issue certain
    regulations “necessary to ensure that there is compliance” with the IDEA.
    Section 1416 authorizes the Secretary to monitor, review and enforce the
    implementation of the IDEA.
    E.M. V. PAJARO VALLEY USD                          23
    include specific learning disabilities,11 autism and traumatic
    brain injury,12 and children between the ages of three and nine
    who experienced developmental delays.13 These amendments
    furthered the IDEA’s overarching substantive goal “to ensure
    that all children with disabilities have available to them a free
    appropriate public education that emphasizes special
    education and related services designed to meet their unique
    needs.” 20 U.S.C. § 1400(d)(1)(A); Forest Grove Sch. Dist.
    v. T.A., 
    557 U.S. 230
    , 244–45 (2009) (noting the IDEA’s
    express purpose as set forth in the statute and holding that
    “[a] reading of the Act that left parents without an adequate
    remedy when a school district unreasonably failed to identify
    a child with disabilities would not comport with Congress’
    acknowledgment of the paramount importance of properly
    identifying each child eligible for services.”).
    The DOE further claims that its perspective is consistent
    with a State and local school district’s duty under the “child
    find” provisions of the IDEA. See 20 U.S.C. § 1412(a)(3).
    The DOE argues that considering a child’s condition under
    only one possible category of disability, when more than one
    might apply, elevates a myopic concern with the child’s
    specific classification over determining the child’s actual
    educational needs. See Heather S. v. Wisconsin, 
    125 F.3d 1045
    , 1055 (7th Cir. 1997) (noting “whether Heather was
    described as cognitively disabled, other health impaired, or
    11
    See Education for All Handicapped Children Act of 1975, Pub. L. No.
    94-142, § 4(1), 89 Stat. 773, 775.
    12
    See Education of the Handicapped Act Amendments of 1990, Pub. L.
    No. 101-476 § 101, 104 Stat. 1103.

    See Individual with Disabilities Education Act Amendments for 1997,
    Pub. L. No. 101-105, § 602(3)(B), 111 Stat. 37, 42–43.
    24              E.M. V. PAJARO VALLEY USD
    learning disabled is all beside the point. The IDEA concerns
    itself not with labels, but with whether a student is receiving
    a free and appropriate education.”); see also 20 U.S.C.
    § 1412(a)(3)(B) (“Nothing in this chapter requires that
    children be classified by their disability so long as each child
    who has a disability listed in section 1401 of this title and
    who, by reason of that disability, needs special education and
    related services is regarded as a child with a disability under
    this subchapter.”).
    Where a statute speaks clearly to the precise question at
    issue, we “must give effect to the unambiguously expressed
    intent of Congress.” Chevron, U.S.A., Inc. v. Natural Res.
    Def. Council, Inc., 
    467 U.S. 837
    , 842–43 (1984). However,
    “if the statute is silent or ambiguous with respect to the
    specific issue, the question for the court is whether the
    agency’s answer is based on a permissible construction of the
    statute.” 
    Id. at 843.
    The Supreme Court has noted that deference may be
    extended to an agency’s perspective not only when it
    exercises its rulemaking authority, but also when an agency
    authorized to administer a statute interprets its own regulation
    or the statute by other means. In Chase Bank USA, N.A. v.
    McCoy, 
    131 S. Ct. 781
    (2011), the federal agency presented
    its position in an amicus brief and the Supreme Court held:
    “we defer to an agency’s interpretation of its own regulation,
    advanced in a legal brief, unless that interpretation is ‘plainly
    erroneous or inconsistent with the regulation.’” 
    Id. at 880
    (quoting Auer v. Robbins, 
    519 U.S. 452
    , 461 (1997)). In
    Capistrano Unified School District v. Wartenberg, 
    59 F.3d 884
    (9th Cir. 1995), the DOE clarified its position in a “letter
    to all chief state school officers,” and we held that the agency
    was “entitled to deference in its interpretation of the statute,
    E.M. V. PAJARO VALLEY USD                     25
    because the interpretation is based on a permissible
    construction of the existing statutory language.” 
    Id. at 894.
    The Supreme Court has recognized that even where the
    express delegation of specific interpretive authority is implicit
    and the agency has not engaged in the process of rulemaking
    or adjudication, an agency’s decision may still be entitled to
    Chevron deference. United States v. Mead Corp., 
    533 U.S. 218
    , 229–30 (2001). Moreover, even when an agency’s
    decision does not qualify for Chevron deference, “an
    agency’s interpretation may merit some deference whatever
    its form, given the ‘specialized experience and broader
    investigations and information’ available to the agency, . . .
    and given the value of uniformity in its administrative and
    judicial understandings of what a national law requires.” 
    Id. at 234
    (quoting Skidmore v. Swift, 
    323 U.S. 134
    , 139–40
    (1994)). We need not determine whether DOE’s policy
    letters and amicus brief command Chevron deference as we
    find its interpretation of the statute persuasive under
    Skidmore.
    Here, as the district court’s resort to a canon of
    construction implicitly admits, Congress’ intent is not clear.
    Title 20 U.S.C. § 1401(3)(A)(i) offers a number of ways in
    which an individual can qualify as a “child with a disability.”
    Some of the proffered categories are quite specific, for
    example: “orthopedic impairments,” “autism,” and “traumatic
    brain injury.” Other categories appear to be relatively broad,
    such as “intellectual disabilities,” “hearing impairments,” and
    “serious emotional disturbance.” It is not clear from the
    statute whether the category “other health impairments” was
    intended as an alternate category or an additional category.
    In other words, Congress did not indicate whether “other
    health impairments” was limited to disabilities that did not fit
    26              E.M. V. PAJARO VALLEY USD
    into any of the other listed categories or included disabilities
    that might also fit within another category.
    Because Congress was not clear, we must consider the
    DOE’s interpretation. We find neither of the grounds
    advanced in support of a restricted interpretation of the statute
    to be persuasive. Certainly, the application of a canon of
    construction should yield to Congress’ purpose in passing the
    IDEA of ensuring that all children with disabilities have
    available to them a free appropriate public education.
    20 U.S.C. § 1400(d)(1)(A). Children with disabilities will be
    disadvantaged if they have to select one category to the
    exclusion of any other category. In many instances, neither
    the child nor the parents will initially know which category
    encompasses the child’s disability. Indeed, compelling a
    selection of one category seems contrary to the school
    district’s child find duty.
    Upon further inspection, the second proffered ground, a
    fear that allowing a disability to qualify under more than one
    category will “negate and render superfluous” the distinct
    requirements for various categories, proves to be unfounded.
    As the DOE asserts and the district court found, the
    regulations that defined “specific learning disability” and
    “other health impairments” in California in 2005 pertained to
    two different categories of impairment with distinct criteria.
    Viewing the requirements side by side reveals their
    distinctiveness.

    A severe discrepancy, which all parties agreed in 2005
    required a difference of 22.5 points between tested ability and
    performance, is not the same thing as a condition that limits
    “strength, vitality or alertness.” Also, it appears that a
    “disorder of the basic psychological processes” is distinct
    from “chronic or acute health problems.” Of course, a
    “disorder” could also be a “health problem,” but presumably
    a child could be otherwise very healthy and still have a
    “disorder of the basic psychological processes.” The third
    criterion was also different. An “other health impairment”
    only required a showing that the condition adversely affects
    the child’s educational performance, whereas a “specific
    learning disability” required a showing that other educational
    tools were inadequate. Perhaps, as the district court found,
    the third criterion for an “other health impairment” might be
    14
    As noted, both the California Education Code and the Code of Federal
    Regulations have been amended since 2005.
    28              E.M. V. PAJARO VALLEY USD
    easier to meet than the third criterion for a “specific learning
    disability,” but the different provisions of the categories’
    other criteria indicate that an “other health impairment” is not
    necessarily easier to show than a “specific learning
    disability.” Regardless of the comparative difficulty of
    qualifying for benefits under the different categories, the two
    categories definitely have different requirements and appear
    to address different facets of disabilities. Thus, the fact that
    a particular child might qualify under both categories is in no
    way contrary to or inconsistent with Congress’ purposes in
    enacting the IDEA. A contrary position would create the
    possibility that a child with a disability could be denied
    special education benefits not because he did not qualify for
    benefits, but because the child, his parents, or the school
    district’s initial selection of one category barred consideration
    of a more appropriate category.
    The district court, faced with a question of first
    impression, reasonably turned to a canon of construction to
    interpret an ambiguous statute. On appeal we have the
    benefit of a presentation by the DOE, which is charged by
    Congress with enforcing the IDEA. Because Congress did
    not clearly address the issue, and because we determine that
    the DOE’s interpretation of the statutes and regulations is
    reasonable and furthers the overall intent of the IDEA, we
    defer to the agency’s interpretation. Accordingly, we hold
    that a “child with a disability” may seek to qualify for special
    education benefits under more than one of the categories
    listed in 20 U.S.C. § 1401(3)(A)(i).
    E.M. V. PAJARO VALLEY USD                    29
    D. Plaintiffs Have Not, and Cannot, Show that
    PVUSD Unreasonably Denied E.M. Special
    Education Benefits in 2005 Under the “Other
    Health Impairment” Category
    Our decision that E.M. may qualify for special education
    services under the other health impairment category does not
    answer the question whether he did qualify for services in
    2005, or more to the point, whether Plaintiffs can show that
    PVUSD unreasonably failed to extend special education
    benefits to E.M. in 2005 based on his “other health
    impairment.” In a usual case, we would remand for the
    district court or the ALJ to determine such a factual question
    in the first instance. However, over the last eight years this
    matter has been before the ALJ twice, before the district court
    thrice, and is now before us a second time. E.M. has
    graduated from high school. Accordingly, judicial efficiency
    and fairness to all concerned recommend that we review the
    existing record to consider whether a remand would be futile
    and would needlessly prolong this litigation.
    The record is not clear as to when the possibility of E.M.
    qualifying for educational benefits under the OHI category
    first arose. There is no indication that this possibility was
    specifically mentioned by anyone in 2004 or 2005. As we
    noted in our prior opinion, Plaintiffs’ prayer in their January
    2006 filing with California’s Office of Administrative
    Hearings included the words “other health impairment.”
    
    E.M., 652 F.3d at 1006
    . However, the filing as a whole does
    not present any evidence or arguments that E.M. met the
    30                 E.M. V. PAJARO VALLEY USD
    criteria for qualifying under the other health impairment
    category.15
    A review of the ALJ’s decisions show that all parties were
    focused on E.M.’s auditory processing disorder. The issues
    presented were broad, including whether PVUSD fulfilled its
    child find and search and serve obligations, whether PVUSD
    denied E.M. a free and appropriate public education and
    whether PVUSD failed to assess E.M. in all areas of
    suspected disability.

    The prayer in the initial complaint to the Office of Administrative
    Hearings read:
    To be found eligible for special education and related
    services under the IDEA as a child primarily with a
    learning disability and also as a child having an other
    health impairment due to his auditory processing
    deficits as outlined in paragraphs 12, 18, 21 and 22
    above.
    Paragraph 12 simply recites that, based on Dr. Wright’s findings, Plaintiffs
    requested that E.M. be assessed for special education services. Paragraph
    18 recites efforts by Dr. Wright in 2005 in support of E.M.’s request for
    benefits and concludes with the assertion that E.M. “qualified as a child
    with a learning disability with additional deficits in auditory processing.”
    Paragraph 21 alleges that based on the assessments and observations of
    E.M., he “clearly met the criteria of a learning disability.” Paragraph 22
    reiterates that E.M. “has a learning disability and moreover a central
    auditory processing disorder.” It states that the audiologist “found
    problems with short-term memory, language processing and an
    impairment in background noise,” and that E.M.’s verbal responses
    “require changing an auditory input into a more complex output involving
    conscious thought and mediation by language processing.” All of the
    paragraphs appear to address the criteria for a “specific learning disability”
    rather than for an “other health impairment.”
    E.M. V. PAJARO VALLEY USD                         31
    The ALJ’s report concentrates on Plaintiffs’ claim that
    E.M. was eligible for services under the “specific learning
    disability” category, but it also considered Plaintiffs’
    allegations that PVUSD failed to assess E.M. “[i]n the areas
    of auditory processing, hearing and behavior.” The ALJ
    found that Ms. Viall administered the Spanish and English
    versions of a test that included a subtest for auditory
    processing and that Plaintiffs had failed to establish that
    PVUSD failed to assess E.M. “in the suspected area of
    disability of auditory processing.”16 As to testing for hearing,
    the ALJ noted that E.M.’s “initial evaluation report dated
    October 13, 2004, states that [E.M.] was screened for hearing
    problems” and that E.M. “passed the hearing screening.” The
    ALJ found that Plaintiffs had failed to show that PVUSD had
    failed to assess E.M. in the area of hearing and commented:
    “[w]hile [E.M.] listed this as an issue, he presented no
    evidence in support of his claim that [PVUSD] failed to
    screen his hearing.”
    As noted, the criteria for qualifying for special education
    benefits under the “other health impairment” category were
    16
    The ALJ further noted:
    While [E.M.] subsequently obtained an assessment
    from a private audiologist who determined that [E.M.]
    had an auditory processing disorder (although as
    [PVUSD] correctly points out, her ultimate conclusion
    in that regard was vague) there was no persuasive
    evidence that Ms. Viall was not appropriately trained
    and qualified to administer the TAP-R, which, as
    determined above, tests “auditory processing.” The fact
    that [E.M.] obtained a different result from a different
    test administrator does not detract from the fact that
    [PVUSD] did assess [E.M.] in the area of auditory
    processing.
    32              E.M. V. PAJARO VALLEY USD
    (1) limited strength, vitality or alertness (2) due to chronic or
    acute health problems, that (3) adversely affects the child’s
    educational performance. Here, there is no suggestion that
    E.M. had limited strength or vitality, but his auditory
    processing disorder might well have limited his “alertness.”
    However, the record, rather than supporting this possible
    connection, indicates that when E.M. was tested for hearing,
    the results were normal, and that Plaintiffs failed to proffer
    any contrary evidence.
    It is now too late to develop new evidence as to E.M.’s
    “alertness” in 2005. The existing evidence suggests that E.M.
    did not have limited “alertness.” Ms. Viall and Nancy
    Navarro, the resource specialist who assessed E.M., reported
    that he was alert and responsive during assessment. E.M.’s
    fourth and fifth grade teacher testified that she believed E.M.
    was no more distractable than her other students, and his sixth
    grade teacher reported that after she worked with E.M. on his
    attention, his attention to tasks improved significantly.
    Moreover, there was evidence that none of his teachers, nor
    the speech and language therapists, thought that E.M. had
    trouble following oral directions. This evidence might not
    prove that E.M. was alert, but is more than sufficient, absent
    any contrary evidence from 2004 and 2005, to compel a
    finding that in 2005 PVUSD did not unreasonably fail to
    diagnose E.M. as having limited alertness.
    Limited alertness is the criteria for eligibility for benefits
    under the “other health impairment” category that E.M. was
    most likely to meet. Because Plaintiffs have failed to show
    that PVUSD unreasonably failed to diagnose limited
    alertness, we need not consider whether there was evidence
    that E.M. met the other criteria for eligibility under the OHI
    category. Nonetheless, we note that our review of the record
    E.M. V. PAJARO VALLEY USD                    33
    reveals nothing to suggest that E.M. suffered from chronic or
    acute health problems. Furthermore, even assuming that
    E.M. had limited alertness, there is scant evidence that this,
    rather than other causes, such as his failure to complete his
    homework, adversely affected his educational performance.
    IV
    We can hope that today, with the evolution of the law and
    improved testing, a child with a disability, such as E.M., will
    not have to wait three years to be determined eligible for
    special educational services. However, our task is to
    determine whether PVUSD’s past determinations were
    unreasonable. We conclude that they were not.
    PVUSD was not insensitive to Plaintiffs’ request that
    E.M. be assessed. It formed an IEP team and had E.M. tested
    and evaluated. Morever, PVUSD did not deny E.M. benefits
    on the basis of some subjective evaluation or opinion, but
    because E.M.’s test scores did not show the severe
    discrepancy between his ability and achievement then
    required. Plaintiffs have not shown that PVUSD’s decision
    was unreasonable.
    We do agree with Plaintiffs and the Department of
    Education that a child with an auditory processing disorder,
    such as E.M., may seek special education services pursuant
    to more than one of the categories listed in 20 U.S.C.
    § 1401(3)(A). The DOE is charged by Congress with
    administering the IDEA and its interpretation of the statute is
    permissible and furthers Congress’ intent in enacting the
    IDEA. Accordingly, we defer to its position. See Mead
    
    Corp., 533 U.S. at 234
    –35.
    34              E.M. V. PAJARO VALLEY USD
    Finally, while we recognize that a child with an auditory
    processing disorder may qualify for special educational
    services under the “other health impairment” category, we
    conclude that Plaintiffs cannot show that PVUSD was
    unreasonable in 2005 in failing to diagnose E.M. under the
    OHI category. Our review of the record reveals a dearth of
    any evidence that in 2005 E.M.’s auditory processing disorder
    manifested itself by limiting E.M.’s alertness or that the
    disorder was due to chronic or acute health problems.
    Plaintiffs over the last eight years have broadly challenged
    PVUSD’s alleged failure to fulfill its child find obligations
    and failure to assess E.M. in all areas of suspected disability.
    We doubt that Plaintiffs have any additional evidence
    concerning E.M.’s “other health impairment” in 2005 and
    question whether such evidence, if it exists, could now be
    admitted.
    Accordingly, we AFFIRM the district court’s judgment
    in favor of PVUSD.
    Each side shall bear its own costs.
