The report describes the results from a survey of the study-release policies of the 50 State correctional systems, the District of Columbia Department of Corrections, and the Federal Bureau of Prisons. The data reported are for the year 1971, and they were collected during 1972. Every correctional agency responded to the survey questionnaire and, of the 52 agencies contacted, 42 operated study-release programs at the time of the survey. Of a total of 3,087 offenders who had participated in study-release during the year, only 74 (2 percent) absconded from the program. Forty agencies indicated that study-release helped their rehabilitation efforts. (Author)
