This report presents findings regarding design and implementation of school-to-work (STW) efforts in Job Corps Model Centers. Following an introduction, Chapter two argues that Jobs Corps constitutes a natural context for implementing STW systems because its traditional practices to some degree provide a solid foundation on which to lay STW principles. Chapter three addresses these two keys to implementing STW in the Job Corps context: need for a clearly articulated vision and consistency with the vision in the larger STW context. Chapter four examines the model centers' efforts to build the organizational structure necessary to implement STW reforms. Chapter five discusses how school-based learning (SBL) evolved and examines STW's effect on structure and content of classroom training and the model centers' success in integrating classroom training to replicate STW best practice methods. Chapter six addresses the model centers' implementation of work-based learning principles and practices, implementation challenges, and effective practices and implementation strategies. Chapter seven discusses areas related to connecting activities: strategies to connect worksite and SBL; staff development and training; linkages for the post-program period; and STW stakeholders and their roles. Chapter eight explores evolution and sustainability of STW efforts at the model centers. Chapter nine highlights challenges model centers faced in sustaining a dynamic, evolving STW initiative. Appendixes contain 30 project profiles and 21-item bibliography. (YLB)
