There will be a difference between the two sets of figures as offenders may begin and complete a programme in different years and some offenders will fail to complete the programme. The reasons for non completion vary but include, transfer, breach of programme requirement, removal of programme requirement by the court or receipt of a custodial or other sentence. These figures have been drawn from administrative data systems. Although care is taken when processing and analysing the returns, the detail collected is subject to the inaccuracies inherent in any large scale recording system.
Reconviction rates are not measured on a programme by programme basis. Instead NOMS relies on research evidence to determine effectiveness.
