The practice and promise of policy analysis and program evaluation to improve decision making within the U.S. federal government

This chapter draws on a 40-year history of patchwork efforts to use data to inform the development of public policy and shape its implementation. I begin with a description of the evolution of the policy process, drawing largely on experiences within the U.S. Departments of Health and Human Services, Education, and Labor. All three agencies have been major supporters of and contributors to advances in the methods of policy analysis and the use of program evaluation to guide decision making. The chapter draws on the roles of these agencies in laying the groundwork for the current emphasis on evidence-based policymaking, in part because of their leadership roles and in part because of the author’s first-hand experience working with these agencies. Of particular note is its attention to the lead up to the present context in which policy analysis and program evaluation are central to both the policy development and monitoring processes. The chapter ends with a discussion of the current movement to create and use credible evidence on the impacts and cost-effectiveness of programs, policies and practices as the foundation for more efficient and effective government and, where evidence is lacking, for integrating a knowledge-building agenda into the roll-out of strategies for change.
