Charlie Maynard:To ask the Secretary of State for Justice, what assessment he has made of the efficacy of the offending behaviour (a) programmes and (b) interventions offered in prisons. \p Jake Richards: HM Prison and Probation Service (HMPPS) expects that all programmes and interventions meet the evidenced standards for what works to reduce reoffending and promote desistance. This includes being able to evaluate them. We expect our programmes and interventions to be either accredited or centrally approved to ensure they meet those evidenced standards.

The Correctional Services Accreditation and Advice Panel (CSAAP), an independent group of experts, provides HMPPS with accreditation recommendations to inform their accreditation for use across prisons and probation. CSAAP expects programmes to be designed and delivered based on the best international evidence and requires evaluations to be conducted before they can recommend accreditation.

The Ministry of Justice and HMPPS have developed a comprehensive research and evaluation strategy for accredited offending behaviour programmes. This strategy aims to assess the implementation of these programmes, along with their short-term and long-term outcomes, in an iterative manner. The objective is to establish a thorough understanding of programme delivery and its impact on reoffending and other outcome measures among various participant groups.

HMPPS also has a National Framework for Interventions (NFI) Policy Framework which provides a mechanism for ensuring that those interventions delivered regionally and in lower volumes than our accredited programme offer, including those delivered in collaboration with our third sector partner organisations, also meet the evidenced standards for effectiveness. These standards are consistent with those applied by CSAAP when making accreditation recommendations for offending behaviour programmes across HMPPS. Where interventions are reviewed under the NFI policy framework, it is expected that providers are responsible for the evaluation of their intervention products. Providers do, however, have the option to engage with the Ministry of Justice Justice Data Lab to complete evaluations.

In recent years, several studies and evaluations of HMPPS offending behaviour programmes and interventions have been published in line with the research and evaluation strategy. These are outlined below.
