註釋This report summarises an evaluation of the effectiveness of the two main assessment instruments currently used in probation services in England and Wales : the Level of Service Inventory-Revised (LSI-R) and Assessment Case management and Evaluation (ACE). The study also informs the development of OASys, a national joint prison-probation service assessment instrument. The study examines over 2,000 offenders who were assessed using ACE or LSI-R. The focus is to examine the instruments' ability to predict risk of reconviction, to reliably assess risk and needs of the offender and to measure any changes in these factors over time. Findings indicate that both instruments are able to predict reconviction at a much higher than chance level and have good reliability. In addition, they are able to measure change in a direction that is comparable with their risk of reconviction. The study concludes that both instruments would be suitable for use within probation services to accurately and reliably assess offenders.
