The Probation Service protects the public and create safer communities by helping offenders to desist from committing more crime. We have a strong record of reducing re-offending, managing offenders safely in the community, reintegrating prisoners after release and of providing an effective, efficient and value for money service. We have many success stories of offenders whom we have helped reintegrate into society, as well as statistics that show what we do works.
