A project examined the effectiveness of the Youth Career Development (YCD) Demonstration in facilitating the school-to-work transition of high school seniors. The evaluation involved a 1755-student test group and a 1684-student control group from 30 sites funded by six delivery agents (National Urban League, National Council of Negro Women, SER Jobs for Progress, the Recruitment and Training Program, the U.S. Employment Service, and the Women's Bureau of the Department of Labor). Approaches at these sites included activities to eliminate sex stereotyping; helping Hispanic, black, and other minority youth; use of instituional agencies to facilitate the school-to-work transition; and use of community- and neighborhood-based groups to accomplish the same task. Surveys to measure performance outcomes after a three-month followup period revealed that the school-to-work transition activities produced a statistically significant increase in abilities to find and hold jobs. While postprogram outcomes at the three-month period are modest, significant gains, probably adequate to justify costs, are realized by certain of the delivery agents and certain subgroups of the target population.
