Key Measures

This data relates to the CPS Key Measures reports. These reports focus on several business areas including conviction rates, prosecutions dropped and average working days lost.

This information will be published on a quarterly basis.

Please note:

  1. CPS data are available through its Case Management System (CMS) and associated Management Information System (MIS). The CPS collects data to assist in the effective management of its prosecution functions. The CPS does not collect data that constitutes official statistics as defined in the Statistics and Registration Service Act 2007.
  2. These data have been drawn from the CPS' administrative IT system, which (as with any large scale recording system) is subject to possible errors with data entry and processing. The figures are provisional and subject to change as more information is recorded by the CPS. We are committed to improving the quality of our data and from mid-June 2015 introduced a new data assurance regime which may explain some unexpected variance in some future data sets.
  3. The official statistics relating to crime and policing are maintained by the Home Office (HO) and the official statistics relating to sentencing, criminal court proceedings, offenders brought to justice, the courts and the judiciary are maintained by the Ministry of Justice (MOJ).
