California IEP Transition Services: What Changes at Age 14 and 16 Under AB 438

Transition planning is supposed to be one of the most important parts of a high school IEP. It's the section where the team is supposed to stop thinking only about academic performance and start asking the harder question: what does life after graduation look like for this student, and what is the school actually doing right now to prepare them for it?

In California, the law on transition planning has recently shifted — and the shift gives parents a stronger position to push for meaningful preparation earlier than most families realize.

What California's AB 438 Changed

Federally, IDEA requires transition planning to begin by the first IEP in effect when the student turns 16. California went further. Assembly Bill 438, which took effect July 1, 2025, moves California's transition planning requirements earlier than the federal floor:

• An IEP must include measurable postsecondary goals and transition services starting when the student begins high school — not just at age 16
• The IEP team must formally consider whether transition planning should begin even earlier, by age 14, based on the individual student's needs

This matters practically. A student entering 9th grade at 14 in California now has a legal right to have transition goals and services in their IEP from the start of high school — not just two years later when the federal minimum kicks in.

If your high school student's IEP does not contain a transition plan, you are not wrong to point this out. The absence of a transition component in a high school IEP is a compliance violation under California law, post-AB 438.

What a Legally Compliant California Transition IEP Must Include

Under IDEA and California law, a transition IEP must include:

Appropriate measurable postsecondary goals based on age-appropriate transition assessments — covering at minimum postsecondary education or vocational training, employment, and (where appropriate) independent living skills. These goals describe what the student is working toward after leaving school, not during school.

Transition services — a coordinated set of activities designed to move the student toward those postsecondary goals. Services may include:

• Instruction in specific academic content relevant to the postsecondary goal
• Related services that support transition (e.g., speech therapy targeting communication skills for the workplace)
• Community experiences (job site visits, volunteer work, career exploration)
• Development of daily living skills
• Vocational assessment and training

A course of study aligned with the transition goals — meaning the student's four-year plan of classes should logically connect to what they're working toward. If a student plans to attend a community college, their courses should be preparing them for that. If the student's goal is competitive integrated employment, the course of study should include career and technical education opportunities.

Student involvement: The student must be invited to their IEP meeting when transition is being discussed, and the IEP must reflect the student's preferences and interests — not just the team's assumptions.

The California Transition Assessment Requirement

Transition planning must be grounded in age-appropriate transition assessments. These can be:

• Interest inventories and career aptitude assessments
• Adaptive behavior evaluations covering daily living and self-care skills
• Functional vocational assessments (structured interviews, work samples, job site observation)
• Standardized assessments of independent living skills

If your child's transition IEP is built on generic statements — "student wants to work and live independently" — without any assessment data to back up the goals and services, that is a compliance problem. Ask the team: what transition assessment was conducted, and what specific data informed these postsecondary goals?

Key California Transition Resources the IEP Team Should Be Linking To

A strong California transition IEP doesn't stop at school-based services. It creates connections to post-school support systems before the student turns 22 and ages out of special education.

Department of Rehabilitation (DOR): California's vocational rehabilitation agency offers Pre-Employment Transition Services (Pre-ETS) for students with disabilities aged 14 to 21. Services include job exploration counseling, work-based learning experiences, workplace readiness training, counseling on post-secondary education, and self-advocacy instruction. Students don't need to be eligible for full DOR services to access Pre-ETS.

Regional Centers: For students with intellectual disabilities, autism, or other qualifying developmental disabilities, California's network of Regional Centers provides a lifeline of adult services. But here's the critical practical fact: the DDS (Department of Developmental Services) has intake processes that can take months to years. IEP teams should be actively facilitating referrals to Regional Centers well before a student's 22nd birthday — ideally in 9th or 10th grade.

WorkAbility I: A California Department of Education program that places high school special education students in subsidized, supervised work experiences. Participation requires an IEP and teacher/school approval. If your child's school participates and the student isn't enrolled, ask why.

When Transition Planning Isn't Happening

Common failures in California transition IEPs:

Postsecondary goals are vague or generic. "Student will obtain employment" is not a measurable postsecondary goal. A compliant goal specifies the type of employment, training program, or education setting the student is working toward, based on assessment data.

Transition services aren't actually services. Listing "graduation requirements" as a transition service is not adequate. Transition services must be coordinated activities designed specifically to move the student toward their postsecondary goals.

Student input is token or absent. If the student wasn't invited to their IEP meeting, or if their documented preferences don't appear anywhere in the transition goals, the IEP is not legally compliant.

No agency linkages. For a student in 11th or 12th grade, an IEP without references to DOR, Regional Center, or other adult service agencies is leaving the student and family without a bridge to what comes next.

If the transition component of your child's IEP is inadequate, put your concerns in writing, request a PWN explaining the team's determination on each component, and — if the IEP meeting doesn't resolve it — file a CDE compliance complaint. California's failure to provide compliant transition services is a documented area of systemic weakness.

The California IEP & 504 Advocacy Playbook at /us/california/advocacy/ includes transition planning checklists and templates for disputing inadequate transition IEPs under AB 438 and California Education Code standards. Transition is the part of the IEP that most directly affects your child's adult life — it's worth fighting for.
