Adulthood
Planning for adulthood
The transition from school-based services to adult services is the sharpest cliff in the autism support system. Planning early — ideally starting at 14 — gives families the time to navigate long waitlists and complex eligibility processes.

The 30-second version
- Transition planning should begin in the IEP by age 14 — most families start too late.
- SSI eligibility is re-evaluated at 18 under adult rules — preparation matters.
- Housing waitlists run 5–15 years in most states — apply now.
- Guardianship is one option at 18, not the only one — supported decision-making is a real alternative.
What changes at 18
Age 18 is the legal age of majority in most states, and several things change automatically:
- Medical decisions: healthcare providers may no longer share information with parents or accept parental consent without legal authority — a healthcare proxy or medical power of attorney resolves this.
- Financial accounts: banks may require the account holder's signature independently. Joint accounts or a durable power of attorney are common solutions.
- School records: FERPA rights transfer from parents to the student at 18.
- IDEA procedural safeguards: rights under IDEA (including IEP decisions) transfer to the student at the age of majority.
- SSI: SSA re-evaluates eligibility under adult rules — parental income no longer counts, but the adult disability standard is harder to meet. See SSI for how to prepare.
Employment & vocational rehabilitation
Vocational Rehabilitation is free. Apply before high school graduation.
Housing options & planning
Most public funding for housing has years-long waitlists — apply early.
Legal planning for adulthood
At 18, your child becomes a legal adult. Guardianship is one option — not always the right one.
Why to start at 14
Federal law requires transition planning in the IEP by age 16. Many states require it by 14. But the systems that matter most — housing waitlists, Vocational Rehabilitation eligibility, Medicaid HCBS waiver applications — are not waiting for the IEP to catch up.
Medicaid HCBS housing and community support waitlists often run 5–15 years. A family that gets on the list at 14 may have options at 25. A family that starts at 22 may be waiting until 35. VR services cannot begin until school ends, but eligibility must be established before graduation — a referral in the junior year is not too early.
Legal planning — guardianship alternatives, healthcare proxies, special needs trusts — also takes time and benefits from an attorney who knows your state. Starting at 15 or 16 means decisions aren't made under deadline pressure.
