“This article is about the relationship between recidivism rates and supervision skills used by probation officers (or others who supervise offenders on community-based orders or parole). It focuses on routine day-to-day supervision rather than on intensive supervision programs or other specialized programs or interventions.” Issues discussed include: the impact of probation officer skills; and skills or practices that are consistently related to reduced recidivism-pro-social modeling and reinforcement, problem solving, the use of cognitive techniques, work-client relationship, and risk level of clients.
