Self-determination knowledge and skills are important life skills for success throughout one's life. Therefore, it is important to assess the component skills that lead to self-determination so that appropriate instructional programs, supports, and accommodations to increase student self-determination can be provided. By involving students and families as important team members in the assessment process, valuable information can be gathered, student and family ownership of assessment results is increased, and support for student self-determination is demonstrated. A self-determination approach to assessment can help transition teams gather information about students' needs, strengths, interests, and preferences so that appropriate transition goals can be established. A self-determination focus in assessment can also help ensure that pertinent information is included in students' summaries of performance. Suggestions for practical strategies to promote and assess student self-determination through transition assessment are provided. (Contains 1 figure.)
