Correctional system operation and brief account of its development as background for the presentation of the directions it must take in the future. Modern corrections are moving toward more humane treatment and greater emphasis on rehabilitation and community supervision. The new corrections require extended research and program evaluation, better decision-making, improved organization, and more and better qualified staff. The most conspicuous problems in corrections today are lack of knowledge and unsystematic approach to the development of programs and techniques. Consideration is given to the role of corrections in intake and disposition, probation, alternatives to institutionalization, correctional institutions, parole and after-care, the misdemeanant in the correctional system, the legal status of the convicted person, manpower and training, and creating change.
