New York FAPE Until Age 22: The Katonah-Lewisboro Ruling Explained

Your Child Can Stay in School Until 22 — and the Courts Confirmed It

For years, New York parents heard conflicting answers about when special education services actually end. Some districts said 21. Others said the end of the school year when a student turned 21. The confusion wasn't accidental — it saved districts money when families accepted an early exit.

That ambiguity ended on July 17, 2025, when the New York Supreme Court, Appellate Division, Third Department ruled in Matter of Katonah-Lewisboro Union Free School District v. New York State Education Department that students with disabilities who haven't earned a regular high school diploma are entitled to a Free Appropriate Public Education (FAPE) until the day before their 22nd birthday.

The ruling is binding. Districts across New York must comply.

How the Law Changed

Before 2023, Education Law Section 4402(5) was widely read to cap FAPE at 21. Then the Second Circuit's decision in A.R. v. Connecticut Board of Education (2021) established a principle that states offering public adult education to non-disabled adults couldn't deny equivalent services to students with disabilities at the same age.

New York's adult education statutes closely mirror Connecticut's. In July 2023, NYSED issued Formal Opinion of Counsel No. 242, advising districts that students with IEPs could remain in school until 22. Several districts pushed back. Katonah-Lewisboro and Mahopac both sued NYSED, arguing the Commissioner had overstepped.

The trial courts initially sided with the districts. But the Appellate Division reversed those decisions in July 2025, confirming that NYSED's interpretation was correct and that the Commissioner has broad authority to enforce the age-22 standard.

What This Means for Your Child's IEP

Three practical implications flow from this ruling:

The exit date is the day before your child's 22nd birthday. Not the end of the school year when they turn 21. Not whenever the district decides the student has "aged out." The legal obligation runs until one day before the student turns 22, provided they haven't earned a Regents or Local diploma.

NYSED recommends extending through the school year. In its October 2025 memorandum, NYSED encouraged districts to consider continuing services through the end of the school year in which the student turns 22, rather than forcing a mid-year exit. This is a recommendation — not a legal mandate — but it gives families leverage to negotiate a smoother timeline.

Non-diploma credentials don't terminate FAPE. Accepting a CDOS Commencement Credential or a Skills and Achievement Commencement Credential (SACC) does not end your child's eligibility for special education. Only a regular high school diploma — Regents or Local — triggers the termination of FAPE.

The District Pushback You Should Expect

Even with clear case law, many districts resist funding that extra year. The state legislature hasn't amended Education Law to provide dedicated funding for the 21-to-22 window, so districts absorb the cost locally. That financial pressure translates into subtle tactics parents need to recognize:

• Pressure to accept a diploma early. Some districts will suggest a student is "ready to graduate" with a Local diploma via the Superintendent Determination pathway when the family hasn't requested it.
• Vague exit language in IEP meetings. Ask the district to identify the legal basis and specific exit date in writing rather than relying on phrases like "aging out" or "program completion" in CSE meetings.
• Deflection to adult services. Districts may argue the student would be "better served" by OPWDD or ACCES-VR programs. Those adult services don't replace FAPE — they supplement it, and the school's obligation doesn't end because an adult agency is also involved.

If your district pushes a premature exit, request the decision in writing and cite Katonah-Lewisboro (2025 NY Slip Op 04211) and NYSED's Formal Opinion of Counsel No. 242. Document everything in the IEP record.

What to Do Now

If your child is between 15 and 20 and hasn't earned a regular diploma, confirm with your CSE that the district acknowledges the age-22 standard. Ask that the IEP explicitly states the projected date of service termination as the day before your child's 22nd birthday.

At the same time, use that extended window strategically. The additional months are valuable for completing OPWDD Front Door intake (which routinely takes 12 to 15 months), finalizing an ACCES-VR Individualized Plan for Employment, and building the independent living and vocational skills that make the transition to adult services smoother.

The Bottom Line

Special education in New York doesn't end at 21. The Appellate Division's July 2025 ruling confirmed what NYSED had been advising since 2023: eligible students have a right to FAPE until the day before they turn 22. If your district tells you otherwise, they're contradicting binding case law — and you have every right to push back.
