Risk and needs assessments are now routinely used in correctional systems in the United States to estimate a person’s likelihood of recidivism and provide direction concerning appropriate correctional interventions.1 Specifically, they inform sentencing, determine the need for and nature of rehabilitation programs, inform decisions concerning conditional release, and allow community supervision officers to tailor conditions to a person’s specific strengths, skill deficits, and reintegration challenges. In short, risk and needs assessments provide a roadmap for effective correctional rehabilitation initiatives. When properly understood and implemented, they can help correctional organizations to provide the types and dosages of services that are empirically related to reductions in reoffending.
