Designing Evaluations, 2012

This publication supersedes PEMD-10.1.4, Designing Evaluations, May 1, 1991. GAO assists congressional decision makers in their deliberations by furnishing them with analytical information on issues and options. Many diverse methodologies are needed to develop sound and timely answers to the questions the Congress asks. To provide GAO evaluators with basic information about the more commonly used methodologies, GAO’s policy guidance includes documents such as methodology transfer papers and technical guides. This methodology transfer paper addresses the logic of program evaluation designs. It introduces key issues in planning evaluation studies of federal programs to best meet decision makers’ needs while accounting for the constraints evaluators face. It describes different types of evaluations for answering varied questions about program performance, the process of designing evaluation studies, and key issues to consider toward ensuring overall study quality.
