Scope note: Diagnosticians do not write transition goals or coordinate agency referrals — that is the case manager's role. This reference covers what you need to know to evaluate transition-age students accurately and document your findings in a way that supports the transition planning process.

Timelines & Triggers
Texas Transition at Age 14 — Two Years Earlier Than Federal
TX Law▼
Texas requires transition planning to begin no later than the first IEP in effect when the student turns 14 — two years earlier than the federal IDEA minimum of age 16. The IEP must include: measurable postsecondary goals, transition services, and a course of study aligned to those goals. The student must be invited to the ARD.
TAC§89.1055(b)(7) — Transition services required beginning at age 14; postsecondary goals; student invited to ARD
IDEA34 CFR §300.320(b) — Transition services definition; federal minimum age 16; Texas stricter
Practical implication: If you are evaluating a student who is or will be 14 before their next ARD, your FIE findings directly inform the transition planning section of the IEP. Document strengths, interests, and functional skills explicitly.
What "Transition Services" Means Under IDEA
TX Law▼
Transition services are a coordinated set of activities designed within a results-oriented process that facilitates movement from school to post-school activities — including postsecondary education, vocational education, integrated employment (including supported employment), continuing and adult education, adult services, independent living, and community participation.
IDEA34 CFR §300.43 — Transition services definition; coordinated, results-oriented, based on individual needs
TAC§89.1055(b)(7) — Transition services in IEP; must be based on age-appropriate transition assessment
Must be based on assessment: Transition services in the IEP must be grounded in age-appropriate transition assessment (AATA). Without documented assessment, transition goals cannot be individualized.
Age of Majority — Rights Transfer at 18
TX Law▼
When a student turns 18 in Texas, IDEA rights transfer from the parent to the student unless the student has been determined incompetent under state law or a guardian has been appointed. The district must notify both the student and parents at least one year before the student turns 18. After transfer, the student is the decision-maker for all IEP matters.
IDEA34 CFR §300.520 — Transfer of parental rights at age of majority; notification one year prior
Texas Ed. Code§29.017 — Transfer of rights; guardianship exception; student participation in ARD
Guardianship planning: For students with ID or significant cognitive disabilities, families should begin guardianship planning before age 18. This is outside the diagnostician's direct role but worth noting in the FIE when relevant.
Student Must Be Invited to Transition ARDs
TX Law▼
Once transition planning begins, the district must invite the student to the ARD meeting. If the student does not attend, the district must take steps to ensure the student's preferences and interests are considered. Failure to invite the student is a procedural violation.
IDEA34 CFR §300.321(b) — Student invited to IEP meeting when transition is discussed; preferences must be considered if absent
TAC§89.1050 — ARD committee composition; student participation required for transition
If student doesn't attend: Document steps taken to obtain their preferences — interviews, surveys, or other means. "Student was invited but did not attend" is not sufficient documentation on its own.
Summary of Performance (SOP) — Required at Exit
TX Law▼
When a student with a disability exits school (through graduation or aging out at 21), the district must provide a Summary of Performance (SOP). The SOP documents: the student's academic achievement and functional performance, and recommendations for accommodations and supports needed to assist the student in meeting postsecondary goals. This is a critical document for college disability services offices and adult agencies.
IDEA34 CFR §300.305(e)(3) — Summary of performance required upon exit from IDEA; academic achievement and functional performance
TAC§89.1070 — Summary of performance; required at graduation or aging out; student and parent copies
Diagnostician connection: The SOP is typically written by the case manager, but draws heavily on FIE findings. A well-documented FIE with functional performance language, clear accommodation rationale, and explicit documentation of the disability's impact makes writing a strong SOP far easier.
