Justice Data Lab re-offending analysis: Warwickshire Youth Justice Service

This document describes the evaluation of interventions provided by the Warwickshire Youth Justice Service (WYJS) to young offenders. The purpose of these interventions was to reduce re-offending rates among youth with a focus on those with violent index offenses. The evaluation used a methodological approach that involved comparing a treatment group of 124 offenders who received interventions between 2007 and 2010 to a matched control group that did not receive WYJS services. The main results indicated that the treatment group had a lower re-offending rate compared to the control group, with a statistically significant difference (p-value of 0.02). However, the evaluation also noted limitations such as potential selection bias, the specificity of the group studied, and the need for a larger sample size to improve the precision of the estimates. The document, which includes detailed statistical analysis and is released under the Open Government License, concludes that the specific services provided by WYJS, rather than standard national practices, may contribute to the reduced re-offending rates observed in the treatment group. **This summary was written by an AI model and therefore should not be considered a definitive summary of the report.
