Research identifying the differences, and the relative importance of those differences, between successful and unsuccessful participants in the Work Incentive (WIN) Program is presented in terms of both successful employment at termination from WIN and employment after WIN participation. Over 800 former and current WIN 1 and 2 participants in Ramsey County (St. Paul), Minnesota were interviewed regarding their socioeconomic and demographic characteristics, attitudes towards work and welfare, and knowledge and understanding regarding penalties and rewards associated with WIN and related Aid to Families with Dependent Children (AFDC) policies and programs. The main test, 76 pages, describes the study and its findings, conclusions, and recommendations in a summary fashion for the nontechnical reader, with two chapters and highlights. Appended material, 248 pages, presents comprehensive technical treatment of the study data for readers interested in a more indepth understanding of the project and its findings, with 129 statistical tables included. Results indicate job success at WIN termination seemed to bear a strong relationship to the employment success of WIN clients at Followup; the WIN program should follow through with clients, as much as possible, to achieve successful termination by assisting with job placement.
