The Criminal History Project team completed a comprehensive survey and analysis of criminal history formulas found in guidelines systems, and the results of the survey were published in the Criminal History Enhancements Sourcebook (2015).
In many guidelines jurisdictions, criminal history enhancements are partially or primarily employed as proxies for risk prevention. But to date, the question of whether these scores are actually valid predictors of risk has been under-explored.
An offender’s record of prior convictions is a major sentencing factor in all sentencing systems, including all U.S.
The Robina Institute of Criminal Law and Criminal Justice is pleased to publish a new policy brief on "Comparing Criminal History Enhancements in Three Jurisdictions" by Dr. Rhys Hester, Robina Institute Research Fellow in Sentencing Law and Policy.
