Research Context

​London Gang Exit (LGE) is a holistic support service to help individuals involved in gangs or at risk of gang violence or exploitation. The programme is being delivered by Safer London with key delivery partners Catch-22, Department of Work and Pensions (DWP) and the Community Rehabilitation Company (CRC). The pan London service is designed to complement and enhance existing local services, matching need to bespoke support across mental health, employment, family support, housing advocacy and specialist support for girls and women.

Research Methodology

MOPAC Evidence and Insight (E&I) are evaluating LGE in terms of the process of implementation, performance management, impact and value for money.

The evaluation aims to employ a diverse range of research methods to gain an in-depth understanding of the LGE projects impact and implementation process:

  • Impact evaluation – for interim reports, a simple pre and post intervention offending analysis was conducted using CRIS (Crime Reporting Information System). This was supplemented with semi-structured client interviews, which offered them a chance to reflect on the perceived impact of participating in LGE on their lives. The final report will seek to employ a Matched Control Sample design to assess impact more robustly with the longer timeframe and larger throughput available.

  • Process evaluation – surveys were used to explore practitioner and client views on the implementation process and clients were interviewed about their experience of LGE. This was supplemented with additional information such as Quality Assurance and evaluation reports and contract meeting minutes.

The final evaluation report will seek to provide a robust assessment of LGE’s impact on client’s reoffending frequency and severity, alongside documenting learning from the whole duration of the programme, in combination with value for money analysis.
