This document discusses transition assessments for students with disabilities. It defines transition assessments as an ongoing process that identifies students' postsecondary goals, strengths, preferences, interests and needs. Transition assessments must be conducted starting at age 16 and include measurable postsecondary goals in education, employment and independent living. Both informal and formal assessments are used to gather data from students, families, teachers and other sources to determine needed transition services. This data is documented and updated annually to guide students' transition plans.
