Prison performance ratings for 2017/18 were based on a data-driven assessment of a prison’s performance through the Custodial Performance Tool (CPT), with ratification by in depth scrutiny of performance over the year through an established moderation process.
Overall performance for each prison in the CPT has been graded into one of four bands. These bands are: 4: Exceptional performance; 3: Meeting majority of targets; 2: Overall performance is of concern; and 1: Overall performance is of serious concern. More information is available here.

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.
