Level of Service Inventory-Revised (LSI-R)
Also known as: LSI-R, Level of Service Inventory, Level of Service Inventory Revised, LSI-R Assessment
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.
Key highlights
- Strong and replicated predictive validity for general recidivism across many jurisdictions and offender populations.
- Combines static and dynamic items, so it both classifies risk and identifies changeable treatment targets across ten domains.
- Grounded explicitly in the Risk-Need-Responsivity model, linking assessment directly to evidence-based case management.
- Widely adopted with extensive norms, training materials, and software support, easing implementation and benchmarking.
- Reassessment of dynamic items lets agencies track change in risk over the course of supervision.

When to use it
Use the LSI-R when you need a validated, general-purpose actuarial assessment of adult offenders' recidivism risk and criminogenic needs to guide supervision level and case planning at intake, sentencing support, or reassessment. It is well suited to mixed probation and prison populations and to agencies that want a single instrument linking risk classification to treatment targets. It is less appropriate for specialized prediction tasks — sexual recidivism among adult males is better served by Static-99 — and it should not be deployed without trained assessors, local validation, and attention to the fairness and calibration concerns that attend any actuarial tool used in justice decisions.
Strengths & limitations
- Strong and replicated predictive validity for general recidivism across many jurisdictions and offender populations.
- Combines static and dynamic items, so it both classifies risk and identifies changeable treatment targets across ten domains.
- Grounded explicitly in the Risk-Need-Responsivity model, linking assessment directly to evidence-based case management.
- Widely adopted with extensive norms, training materials, and software support, easing implementation and benchmarking.
- Reassessment of dynamic items lets agencies track change in risk over the course of supervision.
- Scoring depends on a structured interview and file review, so inter-rater reliability suffers without trained, monitored assessors.
- Cut points and predictive validity can vary across populations and over time, requiring local validation and recalibration.
- Predicts general recidivism well but is not designed for specialized outcomes such as sexual or intimate-partner violence recidivism.
- Like all actuarial tools, group-level accuracy does not ensure correct classification of any single individual.
- Use in sentencing and parole raises fairness concerns when items correlate with socioeconomic status or race.

Frequently asked
What does the LSI-R actually measure?
It measures an adult offender's risk of general recidivism and their criminogenic needs simultaneously, using 54 items across ten domains — criminal history, education/employment, financial, family/marital, accommodation, leisure/recreation, companions, alcohol/drug problems, emotional/personal, and attitudes/orientation. The total score indexes overall risk, while the subscale scores show which dynamic needs are driving it.
How accurate is the LSI-R at predicting recidivism?
Meta-analyses and validation studies report moderate predictive accuracy, typically with AUC values in the high-0.6 to low-0.7 range for general recidivism — comparable to or better than other general risk/need tools. Accuracy varies by population and outcome definition, which is why agencies are advised to validate and recalibrate cut points locally rather than rely on published norms alone.
How does the LSI-R relate to the LS/CMI?
The LS/CMI (Level of Service/Case Management Inventory) is the fourth-generation successor to the LSI-R. It retains the same theoretical RNR foundation and a similar core risk/need scoring scheme but adds structured modules for specific risk/need factors, responsivity considerations, and integrated case-management planning, more tightly coupling assessment to the intervention plan.
