Turning 18 changes who makes decisions about school, health care, benefits, money, work, and college. This page holds the current version of Transcenders’ free California checklist for students with disabilities and their families. Outside California, the federal benefits steps in the next section still apply to your family, and the checklist shows the kinds of steps your state will have versions of.
Printed copies are snapshots. This page is the current version.
Start earlier than you think.
If your child is years from 18, this page is still for you. The families who fare best at 18 started the paper trail early: evaluations kept, records gathered, benefits understood while there was still time to act on them. It is the same work either way. Done early, it is paperwork. Done in the teen years, it is a fight, and fights are costly and tiring in every currency a family has.
SSI and DAC at 18: the two benefits reviews nobody warns you about
Two federal benefits change at 18, and both catch families off guard. The checklist on this page tracks both, next to the school, health, and services steps. Here is what each one means.
SSI at 18: a new decision under adult rules
If your teen already receives Supplemental Security Income (SSI), turning 18 triggers a redetermination. Social Security reviews the case again, this time under the adult disability rules, which are different from the childhood rules. The adult test focuses on whether the condition keeps the person from doing substantial work, so a young person who qualified as a child can be found not disabled as an adult. A large share of families get a no at this review. A no is not the end of the road: you can appeal, and appealing quickly matters. If you appeal within 10 days of the date on the notice, you can usually ask for payments to continue while Social Security decides the appeal.
If your teen has never applied, 18 is often the right time to file a first application. One reason is deeming: before 18, Social Security counts part of a parent’s income as available to the child, which keeps many working families out of the program. Deeming stops at 18. After the birthday, SSI looks at the young adult’s own income and resources, plus a reduction if they live in someone else’s home and do not pay their share of food and shelter costs. Apply close to the 18th birthday, keep every notice Social Security sends, and write down every deadline on it.
DAC: benefits on a parent’s work record
Disabled Adult Child benefits (DAC) are a different program with a similar name problem: many families have never heard of it until a parent retires. DAC pays a monthly benefit to an adult whose disability began before age 22, based on a parent’s Social Security earnings record instead of their own. The parent must be receiving Social Security retirement or disability benefits, or have died with enough work credits. The adult child must be 18 or older and unmarried in most cases, with limited exceptions, such as marriage to another Social Security beneficiary.
The amount is based on the parent’s record: half of the parent’s full benefit amount while the parent is living, and up to three quarters after the parent’s death. Medicare usually follows after two years of DAC payments. Two cautions. First, nothing may be payable yet if no parent has retired, become disabled, or died, so DAC is often a future benefit to plan around rather than a check that starts at 18. Second, DAC counts as income for SSI and can change Medicaid coverage, and the timing of a parent’s retirement claim can change what the whole family receives. Before anyone files, it is worth one conversation with a benefits planner or a special needs attorney who can run the household numbers together.
Where these fit in the checklist
The Turning 18 checklist on this page includes the SSI review at 18, what to gather before the redetermination, and the records that help in both reviews, such as school files, evaluations, and medical history from before age 22 for a future DAC claim.

Not sure which of this applies to your family?
Start with the checklist
Start at 16 or 17 if you can. The checklist covers school rights and records, supported decision-making, SSI review at 18, Medi-Cal renewal, regional center planning, Department of Rehabilitation Student Services, veterans’ education benefits, CalABLE, identification, voting, Selective Service, and the move from an IEP to college accommodations.
This checklist is a starting point, not a complete list of every program, deadline, or option. Program rules, dollar amounts, deadlines, and contact information change often. Confirm details with the agency or office named in the checklist.
Building Credit After 18: A Starter Plan for Young Adults With Disabilities
Request a resource
Do not see the checklist, guide, or timeline your family needs?
Tell us what would help. Families, students, educators, and partner organizations can request a topic for Transcenders to research and build. Examples include another state’s version, a benefits timeline, a school meeting worksheet, or a guide to one program.
Begin your Get Help message with: Resource request:
Requests help set the build queue. A request does not guarantee a publication date, and individual legal or benefits advice still requires a qualified professional.
Get individual help
If you are working through a specific transition problem now, use Get Help. Tell us the young person’s age, your state, what you are trying to accomplish, what you have tried, and any deadline.
For schools and partner organizations
Schools and organizations may share the permanent link or include the current checklist in transition, transfer-of-rights, and exit materials. Please link to this page rather than copying an old PDF to a local drive. That keeps families connected to corrections and updates.
