The ChalleNGe program consisted of three phases. In Phase 1, participants attended a two-week, intensive orientation and assessment. Following this orientation, participants were formally enrolled in the program and considered cadets. The cadets then began Phase 2, which consisted of a 20-week education program focused on preparation for the GED exam and positive youth development. Phases 1 and 2 required the cadets to live on-site and experience a quasi-military environment. During Phase 3, the cadets participated in a nonresidential structured mentoring program for a year.
