The Ministry of Justice publishes statistics showing the total caseload of the probation service (the National Probation Service (NPS) and the 21 Community Rehabilitation Companies) and also staff in post in the NPS. Figures for total probation caseload are published quarterly in the Offender Management Statistics Bulletin, England and Wales:
Figures for NPS staff in post are also published quarterly, in the National Offender Management Service Workforce Statistics Bulletin:
Figures on the average caseload of probation officers are not collected centrally. Individual probation officer caseloads across the NPS are, however, carefully monitored by experienced managers. We are also developing a Workload Management Tool to assist National Probation Service Divisions, which will help with the process of allocating cases appropriately between staff.
