(1) Unless sooner cancelled, an ATC qualification remains valid:
(a) for the period specified by the ATS provider or ATS training provider that granted it; or
(b) if any ATC licence, rating or endorsement on which it is dependent, is cancelled before that time--until the licence, rating or endorsement is cancelled; or
(c) until the holder ceases to be employed by that ATS provider or ATS training provider.
(2) For paragraph (1)(b), an ATC qualification is dependent on a particular licence, rating or endorsement if the ATS provider or ATS training provider that grants the qualification so specifies.
(3) A qualification is not in force during any period of suspension, but is not taken to be suspended by the suspension of any licence, rating or endorsement held by the holder of the qualification.
