This volume is at the core of the Program Evaluation Kit. It takes a step-by-step approach to evaluation, using non-technical language to explain procedures to novice evaluators. This edition reflects the current emphasis on continuous evaluation throughout the process of programme development. New references and the inclusion of evaluation standards are also a feature. The Evaluator's Handbook is illustrated with examples, suggestions, worksheets and sample forms for the reader's own use. At appropriate points, it refers readers to other volumes in the Kit for further information.
