The voucher training program for Work Incentive Program (WIN) clients described within this interim report is a system for providing occupational training to clients through entitlements rather than direct service (client and trainer are in a direct relationship facilitated by the agency). The basic program objective, discussed in the introduction, is to maximize the extent to which clients make occupational decisions, selecting the type of training which they feel is most suitable (in a vocational school or on the job) and negotiating for training without intercession by WIN but within the context of existing statutes and program guidelines. Part I describes the procedures in administering the voucher program and the role of the WIN staff and includes (1) the program design, (2) the voucher process, (3) special counseling and information system, and (4) staff qualification and training. Part II deals with administrative considerations bearing on the feasibility of the vouchering system and contains selected empirical findings from program field tests conducted between 1974 and 1976 in Portland, Oregon and Baltimore, Maryland. Comparisons are made between vouchered (institutional and OJT) and regular clients with respect to demographic characteristics, training occupations, school and/or employer characteristics, length and cost of training, and training completion rates. Complete findings and a summary of findings are included along with sample copies of a voucher and other program materials. (EM)
