Key Points

  • IDEA claims for failure to assess accrue when parents knew or should have known of both the assessment failure and the denial of FAPE.
  • A later clinical diagnosis does not restart the two-year statute of limitations; the clock runs from constructive knowledge.
  • The misrepresentation exception requires intentionally misleading conduct, not merely mistaken professional judgments.
  • The withholding exception requires failure to provide statutorily mandated disclosures, not a general failure to share information.

The Ninth Circuit held on April 22, 2026, that claims under the Individuals with Disabilities Education Act for failing to assess a student for autism accrue when parents knew or should have known of both the school district's failure to assess and that the child was being denied a free appropriate public education, reversing a district court's award of $510,960 in compensatory education.

In a published opinion by Judge Daniel A. Bress, the panel adopted the Third Circuit's interpretation of the IDEA's two-year statute of limitations and rejected the district court's conclusion that the limitations period does not start until a child receives a clinical diagnosis.

A later clinical diagnosis may confirm the problem, but it does not automatically restart the IDEA's clock.

The case, J. R. v. Ventura Unified School District, Docket No. 25-5247, arose from a parent's challenge to the alleged failure to assess the student for autism. After a private psychologist diagnosed the child in 2021, the parents filed a due process complaint on April 8, 2021, seeking relief for educational services dating back before 2019. An administrative law judge had previously ordered $19,000 in compensatory education for the period after April 2019, but the district court reversed that limitations ruling and awarded $510,960 through a special needs trust.

The Ninth Circuit reversed the district court's judgment, vacated the remedial orders establishing the trust and enforcing the judgment, and remanded for further proceedings on attorneys' fees. The court first confirmed appellate jurisdiction under 28 U.S.C. § 1291 despite an unresolved fee request, applying the bright-line rule in Budinich v. Becton Dickinson & Co.

Turning to the statute of limitations, the court analyzed 20 U.S.C. § 1415(f)(3)(C), which requires parents to request a hearing within two years of when they "knew or should have known about the alleged action that forms the basis of the complaint." The panel held that for claims alleging a failure to assess and diagnose, the limitations period begins when parents know or should know (1) the school district's failure to assess, and (2) that their child is being denied a FAPE.

The second requirement is essential, for mere awareness that a school district has not diagnosed a student for a particular disability is of little moment if the education is otherwise meeting the student's needs.

Applying this test, the panel agreed with the administrative law judge that the parents knew or should have known the basis of their complaint by at least 2018. The court noted that the parents had expressed concerns about the child's lack of academic progress, obtained an independent evaluation, and threatened litigation before 2019. Because the parents waited until April 2021 to file, claims based on services before April 8, 2019 were time-barred.

The court rejected the district court's per se rule that a diagnosis alone restarts the clock, characterizing it as turning "the IDEA's objective discovery rule into a subjective standard." It distinguished Draper v. Atlanta Independent School System (11th Cir. 2008), where the school district had failed to conduct required reevaluations, leaving parents without new information. Here, the district conducted multiple assessments over the years, and the parents had their own independent evaluation in 2018.

The court also emphasized that although parents are not experts, the IDEA gives them tools to monitor their child's education. "Parents under the IDEA bear some responsibility for monitoring their children's special education," the panel wrote.

Addressing the two statutory exceptions to the limitations period, the Ninth Circuit adopted the Third Circuit's "high threshold" from D.K. v. Abington School District (3d Cir. 2012). For the misrepresentation exception under § 1415(f)(3)(D)(i), parents must show the school "intentionally misled them or knowingly deceived them regarding their child's progress." The court found no evidence of such intent in the school psychologists' statements, and held the withholding exception under § 1415(f)(3)(D)(ii) inapplicable because the parents identified no statutorily required disclosure that the district withheld.

The panel thus reversed the district court's judgment awarding benefits for the pre-2019 period, vacated the December 2024 remedial order and July 30, 2025 enforcement order, and remanded for proceedings on attorneys' fees. The court did not reach the district's additional challenges to the remedial award.
