In the late 1990s, California legislators funded a statewide, community-based correctional program intended to reduce parolee recidivism. Overseen by the California Department of Corrections, the PreventingParolee Crime Program (PPCP) provided literacy training, employment services, housing assistance, and substance abuse treatment to tens of thousands of parolees. The study found that the PPCP produced modest reductions in reincarcerations and parole absconding, creating the potential for substantial long-term cost savings for California taxpayers. Because the PPCP's positive effects were strongest for parolees who completed their services, future program designers and administrators should consider including mechanisms to improve parolee retention and service utilization. This study also points out the potential benefits of incorporating rigorous evaluation plans into the design and implementation of correctional rehabilitation programs.
