Evaluating neighbourhood justice: Measuring and attributing outcomes for a community justice program

This report from the Australian Institute of Criminology (AIC) examines the effectiveness of the Neighbourhood Justice Centre (NJC) in the City of Yarra, Melbourne, under a community-justice model that brings together legal, social and community services to address crime, disadvantage and dispute locally. 

The study considers three key justice outcomes: overall crime rates, completion of community orders, and recidivism. It identifies significant analytical challenges in attributing outcomes specifically to the NJC model—such as small sample sizes, variability in offender risk profiles and causal attribution issues. 

The report acknowledges that while some positive community justice benefits are evident (including enhanced access, integrated service delivery and local engagement), rigorous outcome measurement remains difficult. 

Key findings include:

⦁ The NJC offers a unique integrated service model: court-based, community-engaged and problem-solving in its approach.
⦁ Reliable attribution of outcomes (e.g., reduction in re-offending) is limited by methodological constraints.
⦁ Broader outcomes—such as increased community confidence, service accessibility and coordination—may be more appropriate for evaluation than narrow recidivism metrics.

The report recommends improved data collection, longer term tracking and mixed methods evaluation designs to better capture program value.

For community work professionals, this research provides insight into how court-linked community justice initiatives can operate and the complex evaluation issues they face. The resource supports evidence-informed planning for integrated justice and community safety initiatives, encouraging realistic expectations about what can be measured and how.
