A case study of the introduction of the Comprehensive Employment and Training Act (CETA) in Boston was conducted (1) to chronicle and analyze the changes in employment and training planning and programs as the federal policy changes from a centralized and categorical policy to a decentralized and decategorized one, (2) to examine the impact of those changes on employment and training programs and institutions, the internal structure and staffing of these institutions, program participants, and the community, and (3) to study how the CETA prime sponsor monitors and evaluates its programs. Open-ended interviews were conducted of strategic members of the city, state, and private institutions which were engaged in either planning or operating employment and training programs. Program data pertaining to client characteristics, enrollments, termination, and work experiences were collected. The eleven principal findings included these: (1) Aside from Public Service Employment, the introduction of CETA has not changed Boston's manpower system much, (2) a restructuring of the administrative system did permit incorporation of several new youth programs, and did permit special attention to the needs of ex-offenders, drug addicts, older workers, and women, and (3) due to the weakness of the local economy and administrative defects in the program there was a substantial cutback of on-the-job training. (This report concludes with twenty-two recommendations.) (EM)
