Self-determination is a predictor of positive in- and post-school outcomes, including access to general education, competitive employment, and community participation. Emerging research has focused on promoting self-determination for all students given alignments with college and career readiness frameworks and equity-based education. However, it is also important to enhance self-determination as students participate in the Individualized Education Program (IEP) goal development process. Empowering transition-age students to lead the IEP goal development process with support from school personnel has the potential to enhance the alignment of IEP goals based on students' strengths, preferences, values, and needs and enhance transition planning and college and career readiness. In this article, we provide an example of how to use a self-determination assessment, the Self-Determination Inventory: Student Report (SDI:SR), and an intervention, the Self-Determined Learning Model of Instruction (SDLMI), in the IEP goal development and implementation process to enhance transition planning and college and career readiness.
