Electronic monitoring performance

Electronic Monitoring service performance of service level measures - national performance.

Note performance relates to the service delivery of radio frequency tags only. It does not include the delivery of the GPS service.

The testing of EMS March 2020 data was significantly affected by COVID-19. The access to the EMS systems to test the data due to the lockdown was not possible initially and afterwards very limited. It was agreed in April by members of the Contract Accountability Meeting (CAM) to accept EMS's provisional figures for March 2020.
