MQPL decency audit

The MQPL survey of prisoners' perceptions is a validated way of gauging the quality of Decency and Safety, which are vital business aims but difficult to define and measure by other means.

Questionnaire scores are made more meaningful by comparing them to what might typically be expected from prisons of a similar type, but the comparison should not be judged at face value without reference to the specific context of the prison in question.

The MQPL survey is undertaken as a part of a rolling three-year programme. The data presented here shows the most recent assessment for each prison establishment.

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