ABSTRACT
This article summarizes the history, current status, and future directions of self-determination research across the globe, with a focus on applications to the education of students with intellectual and developmental disabilities and their transition from school to adult life. Research on the development, implementation, and outcomes of self-determination assessments and interventions is explored. Causal Agency Theory, a theoretical framework for understanding the development of self-determination as a psychological construct, is reviewed, along with research on the importance of self-determination for inclusion, psychological growth, and overall well-being. Specific approaches, models, and perspectives for addressing the support needs of students with intellectual and developmental disabilities, particularly during transitions, are discussed. Assessment and intervention aligned with Causal Agency Theory, including the Self-Determination Inventory and the Self-Determined Learning Model of Instruction, are introduced. Future directions and emerging areas of research are summarized, including issues related to cultural validity, integration of strengths-based approaches, emerging technologies, and systemic changes in schools and communities.
