The document discusses the purpose and components of 18-21 transition programs. The key points are: 1) 18-21 transition programs are located in community settings to provide intensive transition training for students ages 18-21 as they prepare for life after high school. 2) The Boulder Valley School District's 18-21 program has three components: Pathways for higher support, Bridges for less support, and Employment Services to help students gain work experience. 3) The goal is to simulate a weekly schedule and assist students' transition to adult independence through workshops, community experiences, and agency connections.
