All those who are qualified will receive a call for the entrance tests. If you have participated previously and did not pass, you will not be given the opportunity to retake the tests.

The first two phases of the entrance test consist of computer-based tests. The tests measure whether you have the necessary attributes to complete the training and work as an air traffic controller. Attributes of particular interest are:

• Three-dimensional visual imagination (spatial perception)
• Quick perceptive ability
• Good concentration ability
• Simultaneous capacity (ability to handle multiple tasks/information at the same time)
• Decision-making ability
• Coordination ability
• High stress tolerance
• Good teamwork skills

This is how the admission process works

• Phase 0: Application check: It is verified that you meet the admission requirements and have uploaded your high school diploma in the application.
• Phase 1: Initial entrance test: It is not required that you have extensive computer skills. The tests are conducted in English. The original diploma or a duplicate must be obtained and brought to the entrance tests for verification.
• Phase 2: If you pass phase 1, you move on to phase 2, which lasts about 4 hours.
