PADI Course Directors train the instructors and thus lead the PADI IDC (Instructor Development Course). They also are responsible for all levels of professional training for the instructors. They hold the highest and most respected qualification in recreational diving.
In order to become a Course Director, Master Instructors take a special training course for two weeks (CDTC) after going through a worldwide rigorous selection process that examines their experience and training.
A preparation for the CDTC course may be offered to you.
