This evaluation describes two supplementary education interventions: the All Stars Talent Show Network (ASTSN) and the Joseph A. Forgione Development School for Youth (DSY). The ASTSN is a 19-year-old program that provides youth age 5-25 with opportunities to produce and participate in talent shows, thus creating stages where youth can successfully present themselves and contribute to their own development. The DSY is a career and leadership training program founded in 1997. Evaluation of the programs focused on 11 criteria drawn from the literature about the merits of supplementary education programs. Results indicate that ASTSN is functioning at a high level of efficiency and effectiveness at community building, involving young people and their families in purposeful activity, encouraging self-confidence, and enhancing competence in self-presentation. DSY is functioning at an excellent level of efficiency and effectiveness in recruiting and engaging a diverse population of young people in a sustained effort at personal development through continuing guided performances in alien environments.
