Rehabilitation may be a long and complex process and it is not always possible to determine when it is complete. Rehabilitation may continue to be provided on release from prison; this may be in the form of supervision by Probation Services according to sentence length, and/or assistance with accommodation, employment, resettlement, programmes, treatment or other support. This is risk and needs-assessed on an individual basis and in accordance with the sentence plan.
In custody, of the prisoners who participated in offending behaviour programmes in 2007-08. 0.03 per cent. failed to complete due to release and during the same period 5 per cent. of prisoners failed to complete drug treatment programmes due to release. The percentage of these who were released on ECL cannot be disaggregated without disproportionate cost as each prisoner record would have to be checked individually.
Prisoners required to undertake a treatment programme as a condition of their supervision licence are excluded from release on ECL unless arrangements can be made for the programme to be followed in the community.
