Accreditation is a system for ensuring treatment programmes offered to offenders, which aim to
reduce reoffending, have a proper theoretical basis, and are designed in accordance with
the "What Works" literature. To achieve accreditation via the Correctional Services Accreditation
and Advisory Panel, programmes must be assessed to make sure they are targeting the right people,
focusing on the right things, and being delivered in a way that is most likely to reduce reoffending.
Responsibility for delivering substance misuse programmes transferred from
HMPPS to the
NHS from 2011 and
accounts for much of the decrease in overall completions of offender behaviour programmes over the time series.
Programmes offered in custody include domestic violence, general offending, sexual offending,
substance misuse, violence, extremism and gang affiliated offending
