Teachers assess transitional potential after having a meeting with the CSC that works directly with he student and the parents. The student's Individual Education Plan (IEP) is reviewed to measure the levels of independent and academic performance that the students have accomplished. Depending on what goals have been achieved, and depending on the student's independent goals, a determination is made with all members of the team agree.
Transitional service programs usually begin when the student turns 16. This could change, however, depending on the level of readiness of the student to work with assistive technology, behavior within the general ed environment, and the self-determination of the student. This is why ideally it is also possible for the student to start as early as age 14. However, IDEA mandates that students receive services from age 3 through 21. Ofter the services for transition end once the students obtains a high school diploma. If the services available meant for transition were applied appropriately, there should be no problem for a student to be ready for independent of semi-independent life.
