Evaluation is vital and beneficial to any nonprofit organization. An effective evaluation can help identify an organization's successes, share information with key audiences, and improve services. It can confirm that an organization is truly making a difference, or what changes an organization needs to make in order to improve. This book describes what types of information to collect and what questions this information can answer, details the four phases of evaluation and the steps involved in each phase, and provides information on various types of research consultants and advice on selecting one. If you are an organization manager, decision maker, policymaker, funder, researcher, or student studying applied social service research, this guide is an essential resource for your knowledge of effective organizational management.
