This report was prepared as an Evaluation of the School-to-Work Out-of-School Youth (OSY) Demonstration and Job Corps Model Centers. The demonstration programs and Model Centers are alike in attempting to incorporate and adapt school-to-work principles in their services to out-of-school youth. This summary reflects the findings reported in the Final Report for the component of the study focused on the Job Corps Model Centers; as such, it presents a discussion of the design and implementation of STW principles in the Job Corps context, including the Model Centers' objectives and strategies. A companion report addresses similar issues with respect to the OSY Demonstration.
