This study was undertaken in response to expressions of concern about the apparent high dropout and low placement rates for young under-22 Work Incentive Program (WIN) participants. The analysis is based on interviews with 518 young people in 13 cities across the United States who were in the program at some time between July 1971 and the spring of 1973. The objectives of the analysis were to examine patterns of program exposure and to assess their effect on the post-WIN labor force behavior of the respondents. Chapters deal with background of the study, study approach, and significance; the respondents; WIN program participation and leaving the program; the post WIN experience; and a summary with conclusions. Findings presented in the report are said to be interpretable in the context of limited possibilities underlying the goals and structure of the program. As such, WIN is considered not to have strong effects on the lives of those who appear most to need help to become prepared for full, self-sustaining participation in the primary labor market. Findings are seen to show a consistent tendency to provide the higher-potential program exposures to the clients who already have the greatest initial preparation for the labor market. (Author/AM)
