Missouri IEP Transition Planning: When It Starts and What the Law Requires

When Missouri Schools Must Start Transition Planning

Missouri currently requires that a formal transition plan be in effect no later than the first IEP to be in effect when a student turns 16. That means the conversation about postsecondary goals — employment, education, independent living — should start at the IEP meeting before the student's 16th birthday, so the plan is already documented when the clock starts.

But this timeline is changing. Under Senate Bill 638 (codified in Section 167.903, RSMo), Missouri is moving the transition trigger earlier. Effective for the 2027-28 school year, postsecondary transition services must be included in the IEP before the student exits eighth grade, or younger if the IEP team determines it's appropriate. The idea is to align transition planning with the Individual Career and Academic Plan (ICAP), which Missouri already requires by the end of eighth grade for all students.

If your child is currently 14 or 15, the practical advice is the same regardless of which rule applies: push to start formal transition conversations now. Waiting until the legal minimum means losing years of planning runway.

Age-Appropriate Transition Assessments

Before the IEP team can write meaningful transition goals, they need data. Missouri requires age-appropriate transition assessments (AATAs) that evaluate a student's strengths, preferences, interests, and needs across multiple domains — vocational interests, academic readiness, self-determination, and independent living skills.

These assessments aren't optional extras. They're the empirical baseline that every transition goal is supposed to rest on. Without them, the team defaults to boilerplate goals pulled from a goal bank rather than goals tailored to your child.

AATAs must be updated annually as the student matures and their interests sharpen. Common assessment tools include interest inventories, functional skill checklists, and community-based evaluations where the student tries real-world tasks under observation.

If your child's IEP team hasn't discussed or administered transition assessments, request them in writing. The school must obtain your written parental consent before conducting the initial assessments, so they can't proceed without you — but they also can't skip them.

What Goes on Form C

Missouri uses a model IEP form, and the transition plan lives on Form C. This section captures three mandatory components:

Measurable Postsecondary Goals (MPSGs): The IEP team must draft goals in at least two areas — training/education and employment — plus independent living when appropriate. Each goal describes what the student will do after leaving high school, stated in clear, observable terms. A compliant goal reads something like "After graduation, the student will enroll in a two-year welding certification program at a community college." A non-compliant goal reads "The student will explore career options."

Transition Services and Activities: These are the specific actions the school will take during the current IEP year to move the student toward their postsecondary goals. Examples include job shadowing through a community partnership, travel training on a public bus route, or enrollment in a career-technical education course.

Coordinated Course of Study: This is a multi-year outline of the classes the student will take through graduation, linked directly to their postsecondary goals. It should coordinate with the student's ICAP so that academic coursework and career exploration reinforce each other rather than running in parallel silos.

Inviting Outside Agencies

When the IEP team expects that an outside agency — Missouri Vocational Rehabilitation, Rehabilitation Services for the Blind, or the Department of Mental Health — will provide or pay for transition services, they must invite that agency's representative to the IEP meeting. But there's a consent gate: the school cannot send that invitation without your written permission first.

This matters because agency representatives bring information about eligibility timelines, referral processes, and available services that the school team often can't provide. If no one asks for consent to invite them, the meeting proceeds without that perspective, and families miss the window to start agency intake while the student is still in school.

Ask your child's case manager whether an agency invitation makes sense for the upcoming meeting, and sign the consent form early enough for the agency to actually attend.

Annual Reviews and Keeping the Plan Current

The transition plan is reviewed and updated at every annual IEP meeting. This isn't a one-time document filed away in ninth grade. Each year, the team should check whether postsecondary goals still reflect the student's current interests, whether transition services are actually being delivered, and whether the course of study needs adjustment.

If your child's goals have changed — they're now interested in culinary arts instead of auto mechanics, or they've discovered a talent for graphic design — the annual review is where the plan pivots. Don't wait for the school to raise it. Come to the meeting with updated information about your child's interests and ask for the transition assessment data the team used to set the current goals.
