The purpose of this workbook is to help public health program managers, administrators, and evaluators develop a joint understanding of what constitutes an evaluation plan, why it is important, and how to develop an effective evaluation plan in the context of the planning process. It is intended to assist in developing an evaluation plan but not to serve as a complete resource on how to implement program evaluation. Rather, it should be used along with other evaluation resources, such as those listed in the resource section of this workbook.
