Question to the Ministry of Justice:

To ask the Secretary of State for Justice, how many and what proportion of prisoners in each prison have an up to date Offender Assessment System assessment.

Prison and probation officers use the Offender Assessment System (OASys) to help them assess the needs and risks of offenders – specifically, the risk of reoffending and risk of harm which a given offender presents. Based on the resulting assessment, prison and probation officers may then formulate plans designed to reduce those risks; the plans require the offender’s co-operation and engagement.

We cannot answer the question as asked, as the data needed are collected on two systems. Prison population data are collected as a snapshot on a particular date, with which comprehensive data on assessments on prisoners using OASys completed over time cannot be matched.
