Key findings this quarter

One request is being published this quarter: Changing Tunes

Changing Tunes

Changing Tunes delivers music-based rehabilitation programmes in prisons and communities across 21 sites in England and Wales. It uses long-term engagement with professional musicians, with the option for continued support after release, to help participants build positive futures. This analysis looked at male participants who took part in a programme sometime between November 2018 and October 2023.

The overall results do not show a statistically significant effect on a person’s reoffending behaviour.

Justice Data Lab service: available reoffending data

The Justice Data Lab team have brought in reoffending data up to September 2024 into the service. It is now possible for an organisation to submit information on the individuals it was working with between 2002 and September 2024. If you have any questions about the latest available data, please email a member of the team at justice.datalab@justice.gov.uk.
