Prison level performance is monitored and measured using the Prison Performance Tool (PPT). The PPT uses a data-driven assessment of performance in each prison to derive overall prison performance ratings. As in previous years, data-driven ratings were ratified and subject to in depth scrutiny at the moderation process which took place in June 2019.
In the PPT, overall performance in each prison is rated on a 1 to 4 scale. The ratings are 4: Performance is exceptional; 3: Performance is acceptable; 2: Performance is of concern and 1: Performance is of serious concern. Note, this is a slight change from the rating definitions used in the Custodial Performance Tool in 2017/18. More information is available here.
|Annual prison performance ratings||Count|
|2: Of concern||28|
|1: Of serious concern||16|

A prisoner is released in error if they are wrongly discharged from a prison or court when they should have remained in custody, where the prisoner has not deliberately played a part in the error (i.e. the prisoner had no intent of escaping).
Examples include misplaced warrants for imprisonment or remand, recall notices not acted upon, sentence miscalculation or discharging the wrong person on escort.
