This study examined, using data from the National Longitudinal Transition Study-2, the impact of constructs associated with self-determination (i.e., autonomy, self-realization, and psychological empowerment, measured while youth were in secondary school) on postschool (a) employment and payment/benefits, (b) education, (c) independent living, and (d) social engagement outcomes. Findings suggest that up to 8 years after youth exited school, autonomy, self-realization, and psychological empowerment predict postschool outcomes. Psychological empowerment showed a strong relationship with employment wages and benefits, and autonomy and self-realization contributed to predicting independent living and postsecondary education enrollment. Implications for future research and practice are discussed. [At the time of submission to ERIC this article was in press with "Journal of Special Education."]
