This series of comprehensive task force reports on jails, prisons, and juvenile institutions presents overviews of corrective institutions in California, models, survey findings about the current systems, and a wide range of general and specific recommendations. Various tables and charts illustrate the data, which were collected by a review of the literature, site visits, interviews, and questionnaires. Improvement of correctional facilities should include closure of some institutions and extension of community services at the local level. Community interaction with the institutionalized persons is stressed, as well as the significance of orientation towards statewide goals and their achievement for corrective institutions. Objectives of the study and research methodology are discussed. Evaluation of rehabilitative programs and their administration is included. (AG)
