This book reports a 2-year program of recruiting, selecting, training, and developing job opportunities for 168 youth, primarily Negro, from the inner-city ghetto areas of Washington, D.C. Part 1 overviews the project which was designed to provide jobs and income to the young, multiproblem, unemployed poor, and to fill unmet needs for staff and services in the "helping professions" of health, education, welfare, and recreation. Included are (1) a discussion of the New Careers concept, its genesis and development, and the scope of the specific training programs on which this report is based (11 programs for 11 different institutional systems); (2) an analysis of the process and problems of job development, with a definition of this process, and analysis of the outcomes in this program; (3) a discussion of strategies for recruiting and selecting the trainee population; (4) a description of the training model and its individual components--the core group, on-the-job training, specialty instruction, and remediation; (5) a systematic assessment of the occupational, educational, and social functioning of the enrollees during their employment after training. Part 2 contains four detailed reports on individual training programs, "case studies" on the training of Teacher Aides, Counselors in Residential Programs for Children and Youth, Community Mental Health Aides, and Counselor Interns.
