This is volume three of a six-volume guide to the establishment and management of a comprehensive family-support program. This volume explains the role played by evaluation in the evolution of family-support and family-education services, introduces key aspects and important considerations in planning an evaluation, and discusses how to choose a starting point for evaluation. Several evaluation models are examined, as are ways of fostering community commitment and communicating the existence of the program to the community. The guide provides a list of resources in which program evaluators can find practical advice; discussions on various aspects of evaluation, including management information system, needs assessment, and cost effectiveness; the theory and history of evaluation; and services and organizations that are available for help.
