One of the biggest challenges in Restorative Justice is proving that it works. The impact and outcomes of restorative processes are notoriously difficult to measure, yet it’s a field where capturing reliable data is essential not just to its expansion, but survival.
Measuring Impact
The success of RJ is widely recorded as standardised outcome categories, whether it’s a face-to-face conference, an exchange of letters or dialogue via shuttle. But sometimes a meaningful process doesn’t look like a formal outcome at all. It might look like a restorative conversation that helps someone feel heard for the first time, a facilitator asking a well-timed question that shifts something internally, or, someone gaining much needed clarity on their experience of crime, even if the case can’t progress to a formal process. The process is deeply human and the outcomes that matter are quite often difficult to categorise.
Where there are challenges is that to keep delivering RJ and expand services, the impact needs to be evidenced. Funders, commissioners and policymakers need data to justify investment. This can leave service providers in a balancing act between staying true to the principles of restorative practice and meeting the expectations of data-driven reporting.
Quantitative vs Qualitative in Restorative Justice
Perhaps the balance point lies somewhere between the quantitative and qualitative data. In their new 2025 Restorative Practice Guidance, the RJC emphasises a mixed-methods approach which recognises the importance of focus groups and storytelling alongside measurable indicators to allow for a deeper understanding of the effectiveness of restorative processes.
However, collecting qualitative data isn’t always straightforward. Practitioners work with real people who are often talking about some of the most painful or personal experiences of their lives, and it’s important that service users feel supported and respected. Tracking how service users feel at different points in the process and measuring the distance travelled can be a useful way to demonstrate impact, but even that depends on careful communication and explicit consent to share. Asking for feedback at the wrong time can feel intrusive or impersonal, and it’s important not to lose sight of the human element of a restorative process so that service users don’t feel like they are part of a feedback exercise.
Why Mixed Methods Matter
Restorative Justice is, at its core, deeply nuanced. The outcomes that matter most to the people involved are rarely reflected in the data, yet the data is essential to ensuring that this transformative work receives the recognition and support it deserves. Approaches to data collection should reflect that the people involved are more than case studies or tools for feedback, but individuals with unique stories. Numbers give a sense of scale while stories capture the meaning behind them. One without the other only paints part of a picture.
