§ Beverley Hughes
The Prison Service measures its performance in delivering the sex offender treatment programme by completions rather than by the number of participants, because some participants who start the programme may not complete it. The table sets out the targets, completions and completions adjusted in the light of audit quality markings awarded to each programme site (the latter figure representing the Service's final Key Performance Indicator score).

The quality and implementation of the sex offender treatment programme is overseen by the Prison Service's Offending Behaviour Programmes Unit working to standards set and maintained by the independent Prison/Probation Service Joint Accreditation Panel. The Unit develops the programmes, the implementation processes and the audit processes, all of which must then he accredited by the Panel. The Unit ensures that the standards demanded by those processes are maintained by training staff and by annual audits of implementation, carried out to the accredited standards. The Panel also conducts an annual moderating exercise on the audits conducted by the Unit.
