Abstract The National Institute of Justice and the Bureau of Justice Assistance sponsored a nationwide intensive- supervision-probation-and-parole (ISP) demonstration and evaluation program. ISP is a form of release into the community that emphasizes close monitoring of convicted offenders and imposes rigorous conditions on that release. The study was conducted as a randomized experiment. At each site, along with the experimental group, a control group of offenders was established to serve as a comparison. For each offender, data collection forms were completed by the participating agency in the respective jurisdictions. A background assessment recorded demographic information, prior criminal record, drug dependence status, and similar information. The other forms recorded probation and parole services received, participation in treatment and work programs, and recidivism during the 1-year followup. Separate calculations were devised for estimating costs and for measuring program implementation, the effect of the ISP's on recidivism, and the effect on social adjustment. The evaluation found that the most singular success of the programs was in the area of control of the offender. These successes suggest that continued development of ISP's is warranted. source
