To ask the Secretary of State for Justice
(1) what steps his Department has taken to monitor the effectiveness in reducing re-offending of the electronic tagging of offenders currently undertaken by each of the private sector companies contracted to provide such a service;
(2) what research his Department has undertaken into the effectiveness of electronic tagging in reducing reoffending rates.
The Ministry of Justice has undertaken research to determine the relative effectiveness of community order requirements, including curfews (which are enforced by electronic monitoring), at reducing re-offending, for offenders with similar characteristics. This found that offenders who received a punitive requirement (unpaid work or curfew) in addition to supervision were less likely to re-offend and committed fewer re-offences within a two year period compared to those who only received supervision.
In addition, we have also undertaken separate research into the effect of release on Home Detention Curfew (HDC), which is also enforced using electronic monitoring, on recidivism. Compared to similar offenders, this showed that those released on HDC were no more likely to engage in criminal behaviour during the first two years after release from custody than those who were not eligible for release on HDC, even factoring in the additional time spent in the community.
This research is published on the MOJ website and can be located on the following webpages:
We have not made any assessment as to the impact individual providers of electronic monitoring have had on reoffending for the offenders whom they work with.
