This article provides an overview of Positive Youth Development (PYD) and suggestions for the application of PYD principles and practices in therapeutic schools and programs. The historical context of this developmental paradigm is provided as well as a comparison with other perspectives of adolescence. Much like positive psychology, PYD focuses on the promotion of positive growth as opposed to solely attempting to prevent and diffuse negative behavior. PYD can be conceptualized as a philosophy, developmental perspective, and a programming framework. Insights are provided within each of these areas regarding the relevance of PYD to therapeutic settings.
