Level of Service Inventory–Revised (LSI-R)

The LSI-R is a risk assessment instrument designed to identify adult offenders’ likelihood of reoffending and is widely used in corrections. The instrument has been built on extensive empirical evidence about offender risk factors and pilot-tested extensively prior to its formal release. The LSI-R is part of a new, third generation of offender risk instruments known as risk/need assessments, because its items include a balance of historical and demographic static risk factors and an array of dynamic criminogenic need factors. This entry describes the LSI-R, its place among LSI instruments, its content and widespread use, its training protocol, and its validity.
