This booklet identifies basic techniques and methodologies for evaluating training and development programs. It also examines a selected number of methodologies that appear to be applicable to evaluating the results of program performance and achievement in many social and economic programs. Section 1 provides general information on evaluation and reviews some basic assumptions about evaluative research. Section 2 gives a brief explanation of the process of evaluation. Section 3 summarizes several selected program evaluation models, with emphasis on comparing the models and simplifying evaluation designs. Section 4 reviews other approaches to evaluation, and the appendix contains an extensive bibliography, as well as a sample evaluation form. (Author/JG)
