Justice Data Lab Re-offending Analysis: Community Justice Court at Plymouth Magistrates' Court

This document describes an evaluation of the Community Justice Court (CJC) program at Plymouth Magistrates' Court, which aims to reduce local offending by addressing underlying issues through problem-solving meetings. The evaluation analyzed data from 91 offenders who participated in the CJC in 2010, comparing their one-year proven re-offending rate of 41% to a matched control group's rate of 32%. The analysis, which included confidence intervals and measures of re-offending frequency and timing, found no statistically significant differences between the groups. However, the evaluation noted limitations such as small sample size and potential unrecorded characteristics affecting re-offending behavior. It also discussed the impact of negative selection bias and the need for larger sample sizes for more conclusive results. The document, released under the Open Government License, provides detailed comparisons of offender characteristics and emphasizes that the CJC-specific re-offending rates should not be compared to national averages. **This summary was written by an AI model and therefore should not be considered a definitive summary of the report.
