Concerned with the increasing feminization of poverty, the Rockefeller Foundation launched in 1982 a $12 million welfare-to-work research and demonstration project, presently midway into a 5-year evaluation. The Minority Female Single Parent Demonstration project involved four community-based organizations: Atlanta Urban League (Georgia); Opportunities Industrialization Center of Providence, Rhode Island; Wider Opportunities for Women, District of Columbia; and Center for Employment Training (CET), San Jose, California. Although the first three projects produced discouraging results, CET had dramatic results. Findings were the result of random assignment testing, the most rigorous technique known for measuring the effect of a specific program. After spending less than 1 year in the program, more participants got jobs, better jobs, and substantially higher wages than participants in the other programs, and they did better than a CET control group. CET's success was based on the immediacy of its job training, fitting in needed basic skills instruction. Analysis indicated that CET's program differed from the others by the form in which the training was delivered. Key successful features were no tests; no waiting (open entry and open exit); integrated instruction; ties to the labor market; child care; and one-stop, comprehensive services. (YLB)
