This toolkit presents products that were developed as part of the design and instrumentation work on the National Evaluation of school-based Learn and Serve America Programs (NELSAP or "National Evaluation"). The products are specific to a design that the Corporation for National and Community Service (CNCS) presented to the Office of Management and Budget. It is the hope of CNCS that other researchers will benefit from a discussion of design alternatives for experimental studies and from access to instruments that measure students' academic and civic engagement, implementation measures of service-learning in the classroom, and sample recruitment materials. The toolkit has four main sections: general evaluation guidelines for service-learning; developing a rigorous evaluation for service-learning; design instruments and recruitment materials from the National Evaluation; and an annotated bibliography based on literature reviews conducted for the National Evaluation.
