Initial analysis of intensive service supervision revealed that with more thorough initial diagnosis and careful classification, probationers could be grouped on the basis of levels of service required to provide control for emotional and social needs. This classification and service delivery system, while not reducing recidivism, did improve social adjustment indicators, including employment. By identifying some probationers as requiring minimal levels of supervision, resources were released for use with more difficult cases. This reallocation of resources allowed more effective delivery of probation services without increasing costs. Because findings are based on a total sample including males and females and felons and misdemeanants, it was felt that more significant findings might be masked. However, findings based on an analysis of only male felons produced findings very similar to those for the whole sample, i.e., improved ratings on social adjustment measures without a reduction in recidivism. 8 tables and 10 references.
