Tools for All Stages of the System
Different points in the criminal justice system require assessments for different purposes.
The STRONG-R Pre-trial assessment includes static and dynamic items and measures both risk and protective factors. This tool is perfect to determine risk for Failure to Appear (FTA).
The STRONG-R Low-Risk Screener includes static risk and protective items and is used to efficiently identify individuals for placement alternatives or administration supervision. This assessment is most appropriate for subject’s re-entering the system or those on community supervision.
The full STRONG-R includes static and dynamic items and measures both risk and protective factors to inform needs for all criminal justice populations, provide classification information for prison and jail populations, and predict compliance for individuals on community supervision (i.e., probation and parole). Through Vant4gePoint, results are used to develop case plan goals and assign appropriate programming.
Unlike other risk-needs assessments, the STRONG-R is truly gender specific and responsive. While other assessments simply apply different risk cut points for males and females, the STRONG-R has separate predictive models for males and females.
Reliability and validity of the STRONG-R have been established using significant samples sizes of offenders through the pilot (N= 200), initial development (N= 44,010) and updated development (N= 97,650) of the instrument.
All eight models (Violent, Property, Drug, Felony – for both men and women) demonstrate strong predictive discrimination (Area Under the Curve – AUC) and accuracy (ACC), as well as satisfactory to strong levels of calibration (entropy and slope) and the combined SAR metric. Comparing the predictive validity to that of other contemporary tools, the STRONG-R has outperformed across a variety of metrics of discrimination, accuracy, calibration, and combined measures (Drake, 2014; Hamilton et al, 2016), relying not only on AUCs.
You may also review publications about the STRONG-R, including:

- A More Consistent Application of the RNR Model: The STRONG-R Needs Assessment (Hamilton. et al, 2016), published in Criminal Justice and Behavior.
The STRONG-R can be validated using your offender population to maximize its predictive validity even further.
