The overall staffing position of the Northern Ireland Prison Service is kept under regular review. The target staffing level baseline for uniform staff was reviewed and adjusted from 1 April 2007 to take account of existing and projected staffing needs in light of an increasing prisoner population. In addition, the service has reviewed the grades and skills needed to reflect greater emphasis on prisoner engagement, education and rehabilitation work. New types of operational and support staff have been introduced over the past two years and approximately 200 such staff have been recruited. The service is continuing to recruit new grades of staff.
