Key findings this quarter

One request is being published this quarter: The Chrysalis Programme (2012-2017).

The Chrysalis Programme (2012-2017)

The Chrysalis Programme is an integrated personal leadership and effectiveness development programme, working with individuals while they are in prison. This is the first JDL evaluation for Chrysalis, looking at programme participants between 2012 and 2017.

The overall results show that those who took part in the Chrysalis Programme had a lower offending frequency compared to a matched comparison group. More people would be needed to determine the effect on the rate of reoffending and the time to first proven reoffence.

Justice Data Lab service: available reoffending data
