Security audit

An internal audit that assesses, on a four point scale, the level to which effective security procedures are adhered to within each prison.

There is no structured frequency for how often the security audit takes place, with the exception of long term high security prison establishments which are audited annually. The data presented here shows the most recent assessment for each prison establishment.

This measure is part of the public protection section of prisons data. The data source is prison performance ratings (annual).
