Ages 14 to adulthood — the part nobody explains.

• Under IDEA, the IEP in effect when your child turns 16 must include measurable postsecondary goals — what they're aiming for after high school in education or training, employment, and, where appropriate, independent living — plus the transition services that will actually get them there. Many states start at 14, and no state stops you from asking earlier.
• Those goals must be based on age-appropriate transition assessments: interest inventories, work-skill assessments, daily-living checklists, situational assessments at a real job site. If nobody can tell you what assessment the goals came from, that's the first question to ask.
• Your child must be invited to their own IEP meeting once transition is on the table. This is the part parents underestimate — a teenager who can say "here's what I want and here's what I need" in their own words changes the room.
• The school must invite outside agencies likely to pay for or provide services — vocational rehabilitation, the developmental disability agency — with your written consent. Ask for that invitation in writing; it's how the adult-services door gets opened while your child still has a team.
• At least one year before your child turns 18, the school must tell you both, in writing, that educational rights transfer to the student at 18 in most states. That notice is not a formality — it's your cue to start the conversation below.

Ages and specifics vary by state — several start transition planning at 14, and the age of majority isn't 18 everywhere. Your state's Parent Training and Information Center can confirm your local rules for free.

• A regular high school diploma ends IDEA eligibility. That's a real graduation and a real accomplishment — and it also closes the door on special education services the same day. Nobody is required to warn you twice, so know it going in.
• Students who don't take a regular diploma generally stay eligible until the end of the school year in which they turn 21 — 22 in some states. Ask your district, in writing, for the exact cutoff date and put it on a calendar.
• Those last years are not filler. Many districts run 18–21 transition programs based in the community: job sites, apartments, transit training, college classes. Ask what your district has, and ask to visit before you decide.
• You can defer graduation. If your child could earn a diploma but isn't ready for what comes after, you can ask the team to keep them enrolled and continue transition services. Say it out loud early — some teams assume graduation unless a parent raises it.
• Before the last IEP ends, the school must give you a Summary of Performance: what your child can do, what accommodations work, and what supports they need. Colleges and adult agencies will ask for it. Request a copy in writing and keep it somewhere safe.

This is general information, not legal advice, and these laws differ sharply from state to state. What follows is meant to help you ask better questions of someone who knows your state.

1. 1

   Nothing automatically changes about your child at 18

   What changes is who signs. In most states, educational rights transfer to the student on their 18th birthday, and the school starts asking them, not you. Many families sign a simple release so the school can keep including the parent — that alone solves most of the day-to-day problem.

2. 2

   Supported decision-making — the least restrictive option

   Your child keeps their legal rights and formally names people they trust to help them understand choices and think them through. Recognized by statute in a growing number of states, and available as a plain written agreement in others. It fits most young adults who can decide with help, which is most of them.

3. 3

   Targeted tools, used one at a time

   A health care proxy, a durable power of attorney, a representative payee for Social Security, a joint bank account, a FERPA or HIPAA release. Each covers one area and leaves everything else in your child's hands. Most families need two or three of these — not everything.

4. 4

   Guardianship or conservatorship — the heaviest option

   A court removes some or all of an adult's legal decision-making and gives it to someone else. It is sometimes genuinely the right protection. It is also hard to undo, costs money, and courts increasingly expect you to show less restrictive options were considered first. If it's recommended to you, ask specifically: which decisions, and why nothing lighter would work.

5. 5

   Start the conversation at 16, not the week of the birthday

   Talk with your child about what they want to decide for themselves. Talk with a disability rights attorney or your Parent Center — many will walk you through the options for free. And know that this is one of the hardest conversations of the whole journey. Taking it slowly is allowed.

• Age 14–15: transition assessments, first postsecondary goals, chores and money and transit practiced at home on purpose.
• Age 16: your child attends their own IEP meeting; course of study checked against the goal; vocational rehabilitation invited; first conversations about decision-making at 18.
• Age 17: written notice about the transfer of rights; apply for anything with a waiting list; paid or supported work experience if it hasn't happened yet.
• Age 18: rights transfer; put whatever decision-making supports you chose in place; SSI redetermination if applicable; a release so the school can keep talking with you.
• Age 18–22: community-based transition programming, college or training, employment with supports; confirm the exact exit date and request the Summary of Performance before it.

• Center for Parent Information and ResourcesPlain-language transition guides, plus your state's free Parent Training and Information Center — real humans who do this every day.
• National Technical Assistance Center on Transition (NTACT:C)The research base behind transition planning, including what actually predicts employment after high school. Useful when you need evidence to back a request.
• U.S. Department of Education — IDEAThe official text and guidance on secondary transition requirements. The place to verify anything before you quote it in a meeting.
• Social Security — Benefits for Children with DisabilitiesSSI, the redetermination that happens at 18, and work incentives that let a young adult earn without losing everything.
• ABLE National Resource CenterABLE accounts let a person with a disability save money without losing benefits eligibility. Worth setting up early.
• Special OlympicsUnified Sports and Unified Champion Schools continue through the school years, and adult programs keep going after graduation — one of the few social structures that doesn't end at 21.
