In 1999, the Washington State Legislature passed the Offender Accountability Act (OAA). The OAA affects how the state provides community supervision to adults convicted of felony crimes. The Legislature directed the Institute to determine if the OAA achieves reduced re-offense rates (recidivism) and improvements in other outcomes. In this report, we examine how well the risk assessment instrument adopted by DOC—the Level of Service Inventory-Revised (LSI-R)—predicts recidivism in a sample of 22,533 Washington offenders. We also explore possible improvements to the instrument and how a revised classification approach might work within the OAA.
