This report contains an analysis of the Work Incentive Program (WIN) termination data collected and maintained by the Department of Labor, specifically the Office of Manpower Management Data Systems (OMMDS). WIN projects enrolled their first clients in October 1968, nearly 6,000 people. By the end of March 1970, there were approximately 150,000 enrollments and 60,000 terminations. Each enrollment and termination requires the preparation of an individual form which OMMDS maintains in a computerized file for a variety of purposes. This report is an analysis of the above data and an assessment of its accuracy and overall utility. Major sections of this report cover (1) findings and recommendations, (2) a review of the WIN program and reporting systems, (3) the study data base, (4) an analysis of participation in the program, (5) an analysis of biographic characteristics, and (6) an appendix, which includes numerous statistical tables. Based on the findings, recommendations included: (1) Data reporting and processing procedures should be improved, and (2) Several on-site reviews should be made, particularly to determine the impact of WIN on participants under age 22 and to improve their placement level.
