Level of Service Inventory–Revised

Don Andrews, Ph.D.
James Bonta, Ph.D.


The Level of Service Inventory–Revised™ (LSI-R™) is a quantitative survey of offender attributes and their situations relevant to level of supervision and treatment decisions. Designed for ages 16 and older, the LSI–R helps predict parole outcome, success in correctional halfway houses, institutional misconducts, and recidivism. The 54 items are based on legal requirements and include relevant factors needed for making decisions about risk and treatment. The LSI–R Manual explains the use of the LSI–R and summarizes research studies on its reliability and validity.

The LSI–R can be used by probation and parole officers and correctional workers in jails, detention facilities, and correctional halfway houses to assist in the allocation of resources, help make decisions about probation and placement, make appropriate security level classifications, and assess treatment progress.
