Findings indicate that prison admissions would decline substantially if Utah adopted the Minnesota sentencing guideline model. Discrepancies in sentencing Utah's prison admissions were found when simulating both the Minnesota and Utah revised sentencing guidelines models. A large number of those admitted to prison would have been placed on probation or intensive supervision. Parole release decisions do not appear to be associated with risk of subsequent criminal activity. Furthermore, the adoption of objective risk assessment models may lead to an increase in the number of inmates released. Adoption of the National Institute of Corrections classification model would result in the movement of inmates into lower security levels. Further research efforts should be directed at a review and evaluation of sentencing guidelines which include a rigorous design and validation samples of supervision risk. 7 exhibits, 15 tables, bibliography, appendix.
