ATC OJTIs working in ATC schools instructors should be given the opportunity to update their knowledge regularly in operational units.

An exchange of information on the performance of students should be maintained between ATC School and ATC unit.

All controllers shall be trained in accordance with ICAO requirements.

All controllers shall be licensed and shall hold ATC ratings appropriate to the duties they are undertaking.
