תקציר	The Level of Service Inventory-Revised (LSI-R) is a 54-item actuarial assessment of offender risk and need that operationalizes the Risk-Need-Responsivity model. Items spanning ten criminogenic domains are scored and summed into a total that places an offender in a recidivism-risk band, making the LSI-R one of the most widely used and validated correctional case-management instruments in the world.	Static-99, and its age-revised form Static-99R, is the most widely used actuarial instrument for estimating sexual and violent recidivism risk among adult male sexual offenders. It scores ten unchanging, historical risk factors into a total that maps onto a risk category and, via published norm tables, an estimated probability of reoffending — providing a standardized, evidence-based anchor for forensic risk decisions.
