Douglas J. Besharov and Phoebe H. Cottingham present a group papers that provide the most comprehensive and up-to-date look yet at WIAs program performance and impact. The papers were commissioned for a meeting held with staff of the European Commission for a discussion of WIA lessons and the implications for future workforce programming in the United States as well as Europe. They are organized into five areas: 1) understanding WIA, 2) program implementation, 3) performance management, 4) impact evaluations, and 5) future evaluation choices. In addition, they detail how WIA performance management systems function and present various evaluation techniques for assessing workforce programs.
