“Transition assessments are an ongoing process of collecting information on the student’s strengths, needs, preferences, and interests as they relate to the demands of current and future living, learning, and working environments.  This process begins at age 14 or earlier and will continue until the student graduates or exits high school.  Information from this process is used to drive the IEP and transition planning process and to help develop the Summary of Performance (SoP) document detailing the student’s academic and functional performance and postsecondary goals.” (adapted from:  Sitlington, P. L., Neubert, D. A., Begun, W. H., Lombard, R. C., & Leconte, P. J. (2007). Assess for success: A practitioner’s handbook on transition assessment (2nd ed.). Thousand Oaks, CA: Corwin Press. p. 2-3)
