One approach for increasing the use of program evaluation information is to involve potential users more actively in evaluation activities. In this study program staff participated directly as interviewers-and one person even became a coevaluator—and less directly during informal interactive feedback activities. Program staff have used evaluation information primarily to identify technical assistance needs and to modify the program. Increased use has resulted from improved communication, staff perceptions of evaluation relevance and credibility, and staff commitment to the study. In addition to increasing information use, involving staff has expanded the evaluation knowledge base at a relatively low cost.The way program evaluation findings are used has been a .i recurrent theme in evaluation literature for nearly two decades.Evaluators once expected their studies to provide a significant portion of the knowledge base that policy-makers consider when undertaking important decisions about a program. As the evaluation field has matured, evaluators have become more sophisticated about how much evaluation, in fact, is used and how it is used in decision-making.
