This monograph is the second in a series summarizing the work progress of the Human Services Manpower Career Center, a special research and development project funded by the U. S. Department of Labor. This volume describes the work of the Center in designing career ladders and training programs in the areas of child care and corrections. Also included is a description of the mental health career ladder developed prior to the establishment of the Center. From their experiences in developing the career ladders, the Center has extracted a set of guidelines which would be useful to other agencies committed to the development and implementation of career systems in human services agencies, and these are provided in the report. Texts of the class specifications developed for each of the three career ladders as well as some of the more significant research findings are appended. Other monographs are available as VT 016 354, and VT 016 356-016 359 in this issue. (SB)
