The Judicial Oversight Demonstration (JOD) in Milwaukee featured domestic violence courts, probation review hearings, expanded victim services, additional batterer intervention services, and enhanced probation supervision. This process evaluation documents and assesses program implementation for program planners and policy makers. The impact evaluation compares offender supervision, probationer compliance, and rearrest for domestic violence among samples of domestic violence offenders sentenced to probation before and during JOD. JOD was found to increase offender accountability at the cost of higher rates of probation revocation and subsequent incarceration.
