A review undertaken in August 2007 indicated that approximately 120 prisoners serving indeterminate sentences for public protection (IPPs) were in prisons which do not provide accredited offending behaviour or drug treatment programmes. This equated to approximately 4 per cent. of the IPP population and includes those newly sentenced and waiting allocation. The situation will of course change daily as prisoners move. Whether an individual requires a programme, and if so, which programme, will depend upon the assessment of their risk and needs. Not all prisons provide the same programmes.
