DDD Aging-Out Planner (start years early)
School special education ends at 21 or 22 — but adult developmental-disability services have long waitlists, so the time to register is years earlier. This planner organizes the transition: register with your state's DD agency, line up SSI so Medicaid is in place, get transition into the IEP by 14–16, and track the milestones. Covers NJ, PA, DE, NY, MA, MD, CT, and RI, with each agency's intake line — and explains why each step matters, for parents doing this for the first time.

Understand each step (for parents figuring it out)
Explain in depth: Why the waitlist changes everything
Adult developmental-disability services (day programs, job coaching, group homes, respite) are funded through Medicaid Home & Community-Based Services 'waivers.' Waivers have a fixed number of slots, so several of these states run long waitlists. The single most important thing a parent can do is get the young person registered with the state DD agency and onto the list years before school ends - not the summer after graduation.
Explain in depth: The two doors you need open
Adult services almost always require BOTH a state DD-agency eligibility determination AND Medicaid. In most of these states, getting SSI brings Medicaid automatically - so pursue SSI and DD-agency registration together, not one after the other.
Explain in depth: The school hand-off
Transition planning should be in the IEP by age 14-16. Massachusetts has a formal 'Chapter 688' referral the school files at least 2 years before the student exits - make sure it happens. Ask the IEP team who the adult-services contact is and when the referral goes in.
Explain in depth: Guardianship, or something lighter
As a person nears 18, families weigh guardianship versus lighter options like supported decision-making or power of attorney. A person with a developmental disability can often make their own decisions with the right support - this is their life. Talk it through with the state's Protection & Advocacy office or a special-needs attorney before defaulting to full guardianship.
Frequently asked
Why apply so early?
Adult DD services run through Medicaid HCBS 'waivers' that have a fixed number of slots and long waitlists in several of these states. Registering the spring before graduation is far too late — get on the list years ahead.
What do I actually need?
Usually BOTH a state DD-agency eligibility determination AND Medicaid (often via SSI). The planner walks both together and links your state's agency.
Is this advice?
No — it's organization and plain-language explanation. Confirm everything on your state's official DD-agency site, linked in the tool.
