OTAR Part 65 covers Air Traffic Controllers and other Aeronautical Ground Radio Station operators. Future amendment will incorporate Flight Information Service Operators although for the time being these are not included. ATC licences are issued in two variants, Student - during initial training - and Full. Theoretical training for the initial issue of a licence and all subsequent ratings must take place at an approved training establishment. A student licence will not be issued until the successful completion of the initial rating course. All training must take place under the supervision of an appropriately authorised person. Subsequent checks of an ATC licence holder's operational competence are carried out annually. Medical requirements for Air Traffic Controllers are contained in OTAR Part 67.
