The DPSI exam

To obtain the DPSI you must sit an exam, which takes place every year in June and is composed of the following units:

  • Unit 1: interpret consecutively and simultaneously (whispered) in the public services
  • Unit 2: provide a sight translation into English in the public services
  • Unit 3: provide a sight translation from English in the public services
  • Unit 4: translate into English in the public services
  • Unit 5: translate from English in the public services

Why take it?

The DPSI qualification provides you with a valuable entry point in the world of professional interpreting.

Those that pass the exam can add the title 'DPSI' after their name, can apply for membership with the Chartered Institute of Linguists and can apply for registration on the National Register of Public Service Interpreters.

Holders of the DPSI are normally exempt from taking the Diploma in Police Interpreting if they want to work as interpreters for the police.
