On this foundation of theory and research, parole officials adopted policies and implemented practices that focus on results as the measure of success. This new model, "Results-Driven Supervision" (RDS), is a redesign of traditional supervision integrated with theory, research, public policy, practice, and feedback. Three theories of crime causation were selected to build the model: social learning, deterrence, and routine opportunities. The validity and successful application of each theory have been documented. The RDS model requires parolees to be assessed for criminogenic traits, which research has shown can be altered through appropriate interventions. RDS matches offenders with the intervention programs most highly correlated with reductions in recidivism for such offenders. Intervention efforts are broadly classified into four categories or "tracks:" substance abuse, education, cognitive traits, and employment. Depending on the identified needs, an offender could be placed on one or all tracks for intervention. This article includes discussions of local development and delivery of programs, data-driven processes and outcomes, data collection and analysis, the determination of what works, and the national recognition RDS has received. 1 reference
