A study assessed the effects of the 1978 Comprehensive Employment and Training Act (CETA) amendments. While the major focus of the study was on changes in the public service employment (PSE) programs, other areas were examined, including aspects of CETA management, service delivery systems, the role of organized labor, and job placement. The study was based largely on field reviews of a sample of 28 prime sponsors and was conducted about 18 months after the CETA amendments became fully effective. Included among the major study findings were the following: (1) the CETA changes made managers substantially more sensitive to the need of protecting the programs' integrity; (2) while new monitoring and liability requirements led some sponsors to centralize intake under their own direct control, other amendment requirements tended to fragment overall delivery systems; (3) while CETA changes achieved a sharp shift to targeting a more disadvantaged clientele, lowered wage rates reduced the usefulness of PSE services to the community; (4) organized labor played a significant role in about 20 percent of the areas studied; and (5) while CETA reauthorization enhanced the employability of participants, they also resulted in the enrollment of individuals who were less competitive in the job market.
