The use of cost-effective evidence-based practices to reduce offender recidivism, crime rates, and costs is explained. Strategies covered are: establish recidivism reductions as an explicit sentencing goal; provide sufficient flexibility to consider recidivism reduction options; base sentencing decisions on risk/needs assessment; require community corrections programs to be evidence-based; integrate services and sanctions; ensure courts know about available sentencing options; encourage swift and certain responses to probation violations; use court hearings and incentives to motivate offender behavior change; and promote effective collaboration among criminal justice agencies.
