Under the provisions of Title IB of the Economic Opportunity Act of 1964 (as amended), the Public Service Careers Plan B (PSC-B) program, funded by the U. S. Department of Labor, was designed to stimulate permanent employment opportunities for the disadvantaged and to encourage the upgrading of existing low-paid workers in agencies receiving Federal grants-in-aid. In July 1970, grants totaling $12 million were allocated to 127 grant-in-aid recipients in 43 States for the projected entry employment and training of 3,520 disadvantaged and for the training and upgrading of 2,254 existing low-paid workers. This report represents an analysis of the 117 projects that became operational and includes a description of such program components as: (1) program administration, (2) problems encountered by project directors and enrollees, (3) benefits of the program with respect to administration, flexibility and objectivity, communication, and career development, (4) recruitment and selection, (5) orientation program, (6) job development, and (7) education and training. In general, program success varied directly with the style of supervision employed. It was found that contemporary supervisory styles were closely associated with the successful projects, while traditional supervisory practices were more closely associated with the less successful ones.
