What the evidence says
Aftercare programmes and intensive supervision probation (ISP) aim to provide community-based supervision to reduce reoffending among young offenders. The systematic review analyzed 27 studies and found no statistically significant impact on reoffending rates. However, some evidence suggests participation in aftercare programmes may lead to fewer alleged offences immediately following release from custody.
How it works
The intervention is expected to reduce reoffending through increased supervision, accountability, and service access for young offenders transitioning back into the community.
Implementation
The review did not provide details on implementation strategies or challenges encountered during the execution of these programmes.
