In order to avoid external interference in the process and to prevent the graduate or seafarer from accessing the information resources of the Internet, testing is carried out at special automated workplaces.

The pass level for successful passing the test in any direction is 70%. Technical means of control, including audio and video recording are used during the exam.

The CES electronic testing system was licensed with support from the USAID / UK aid Transparency and Accountability in Public Administration and Services / TAPAS project.
