This publication, Guidelines for Evaluators, is the first in the companion series to the Handbook on Monitoring and Evaluating for Results. The Handbook provides an overall context for results-based monitoring and evaluation and reviews tools and techniques for planning and managing monitoring and evaluation activities. The Handbook, however, is primarily directed to programme managers. This publication is specifically for those who actually conduct evaluations. It complements the Handbook by providing guidance on outcome evaluations as they relate to the evaluators. Guidelines for Evaluators presents a conceptual review of outcome evaluation, identifies key differences between outcome and project evaluations, and provides a framework methodology for conducting outcome evaluations. It also includes a sample outline for an outcome evaluation report.
