Through the JUMP legislation, Congress authorized the Office of Juvenile Justice and Delinquency Prevention to award competitive 3-year grants to community-based, not-for-profit organizations or local education agencies to support the implementation and expansion of collaborative mentoring projects. This legislation also provided for a national evaluation of JUMP. This workbook was created as part of the national evaluation. It is designed to guide agencies in conducting evaluations of their own projects, and it refers to many of the data elements used in the national evaluation. Because program evaluation is similar for all mentoring programs, particularly those designed for children and adolescents, the workbook is designed to ensure its use for the evaluation of both JUMP and non-JUMP projects. Thus, any mentoring program can be evaluated by using the worksheets and tools in this workbook. The information in the workbook is intended to enable program administrators to make sound decisions about the structure and content of a program's self-evaluation. The workbook chapters correspond to each of the steps in the self-evaluation process. The first two chapters provide guidance in laying the foundation for the evaluation. The next two chapters provide assistance in the design of an evaluation plan, and the following three chapters assist in data collection. The final chapters provide guidelines for using the data to learn more about the project and sharing this information with others.
