Public managers, contractors, and grantees conducting evaluations for government operate in complex environment where policymakers and commissioners of evaluation expect different types of “evidence” and simultaneously employ different criteria in judging the quality of that evidence. This text provides a road map for evaluators doing business within or for government, and public managers who are expected to assess and use evidence generated by a large variety of evaluation approaches. The book provides checklists and how-to guidance to help students and other readers develop skills in important activities such as: assessing the quality of evidence claims; developing theories of change to guide the design and evaluation of programs and policies; developing learning agendas to bridge the gap between evidence producers and potential evidence users; and increasing the support of public leaders and executives in the generation and use of evidence to inform their decision-making. The authors include end-of-chapter exercises for readers to test their ability to apply the skills described.
