This guide was designed for trainers presenting inservice workshops for program evaluators, teachers, principals, curriculum specialists, and others responsible for school programs. It is keyed to a companion volume, the Program Evaluator's Guide (ED l42 563), the primary source for workshop participants. Developed under the California Evaluation Improvement Project, both guides present detailed information concerning the purposes and processes of program evaluation, the role of the evaluator, and the development of an evaluation plan or design. Instruction is provided in selecting or developing assessment instruments, collecting and analyzing data, reporting evaluation results, and applying the findings. (CP)
