California IEP Transition Timeline and Checklist: Age 14 to 22

The Multi-Year Map Most Families Don't Get

School districts hand parents a transition plan template and fill it in once a year at the IEP meeting. What they rarely provide is the complete chronological picture — the year-by-year sequence of decisions, applications, and agency contacts that determines whether your young adult has a structured life after school or a disorienting gap.

California's transition process spans roughly eight years. Each year has specific deadlines and actions that, if missed, can't be recovered later. Here's the full timeline.

9th Grade (Age 14–15): Early Planning Under AB 438

California's AB 438 (effective July 1, 2025) moved the transition planning conversation earlier. IEP teams must now consider and include measurable postsecondary goals and transition services starting with the first high school IEP — not waiting until age 16.

Action items:

• Request initial transition assessments (career interest inventories, adaptive behavior assessments)
• Discuss the Course of Study — the multi-year plan of classes and experiences aligned with postsecondary goals
• Begin discussing diploma pathways with the IEP team. The earlier this conversation starts, the more informed the decision will be
• If your child has a developmental disability, confirm Regional Center eligibility is active. If they aren't a Regional Center client yet, apply now

10th Grade (Age 15–16): Assessment and Pathway Selection

Action items:

• Update transition assessments with more detailed vocational evaluations
• Review whether the student should take the California Alternate Assessment (CAA) — this determines eligibility for the AB 181 alternate pathway diploma
• Draft the first formal Course of Study linking classroom instruction to postsecondary goals
• Begin practicing self-advocacy skills. The student should start participating actively in their own IEP meetings

Student-led IEP meetings: Many California SELPAs offer student-led IEP training through their transition programs. Teaching your teenager to present their own goals, preferences, and support needs at the IEP table builds the self-advocacy muscles they'll need for every adult service meeting after school exit.

11th Grade (Age 16–17): Formal Activation

This is when federal law requires the transition plan to be active. Under California Education Code § 56345(a)(8), the IEP must include measurable postsecondary goals and transition services.

Action items:

• Ensure the IEP contains measurable postsecondary goals across education/training, employment, and (if appropriate) independent living
• Submit the DOR Student Services request (form DR 203) for Pre-Employment Transition Services. Students ages 16–21 with documented disabilities qualify for Pre-ETS without a formal VR application
• Formally invite the Regional Center service coordinator and a DOR counselor to the annual IEP meeting — put the invitation in writing
• Begin exploring community-based instruction and work experience placements

12th Grade (Age 17–18): Transfer of Rights Preparation

The year before your child turns 18 is critical for legal planning.

Action items:

• The district must provide a formal written "Transfer of Rights Notice" at least one year before the student's 18th birthday
• Draft a Supported Decision-Making Agreement (SDMA) under AB 1663 if appropriate
• If pursuing a limited conservatorship, file the probate petition early to secure a hearing date
• Contact SSA before the 18th birthday about filing an adult SSI claim (income deeming from parents stops at 18)
• Open a CalABLE account

Ages 18–21: Maximizing the Adult Transition Program

Students who received a Certificate of Completion or alternate pathway diploma (not a standard diploma) retain FAPE and can participate in the district's 18–22 Adult Transition Program.

Action items:

• Execute the SDMA or deliver certified Letters of Conservatorship (GC-350) to the school and Regional Center
• Apply for formal DOR Vocational Rehabilitation (VR) services. Be aware of the DOR Order of Selection — apply early
• Request a combined IEP and Regional Center IPP meeting to coordinate the school-to-adult service transition
• Explore the Paid Internship Program (PIP) through the Regional Center — one of the exceptions to the payer-of-last-resort rule
• Identify specific post-school providers (day programs, SLS agencies, job coaches) and confirm capacity

Exit Year (Age 22): The Final Handoff

Action items:

• Calculate the exact exit date using the birthday-month rules under Ed. Code § 56026(c)(4)
• Ensure the district provides a detailed Summary of Performance (SOP)
• Confirm all adult services are in place and providers have accepted referrals — there should be no gap between school exit and the start of Regional Center or DOR services
• Transfer the SOP, diagnostic records, and assistive technology documentation to the college DSPS office, DOR counselor, and/or Regional Center

SELPA Transition Resources

Your local Special Education Local Plan Area (SELPA) is a resource most families underuse. SELPAs coordinate special education across school districts in their region and typically maintain:

• Transition planning guides and checklists specific to their member districts
• Interagency agreements with DOR and Regional Centers
• Staff training resources for transition coordinators
• Community resource directories for adult service providers

Contact your SELPA's transition coordinator directly — they can tell you exactly what programs are available in your area and which agencies have active cooperative agreements with your district.

The California IEP Transition to Adulthood Guide consolidates this entire timeline into a structured workbook with decision worksheets at each stage — the Transition Timeline Planner maps every action item to specific ages, the Diploma Decision Worksheet walks through the graduation pathway analysis, and the Agency Communication Log tracks every interaction with schools, DOR, and Regional Centers.
