The Instructor Development Course (IDC) is made up of two parts - the Assistant Instructor (AI) course and the Open Water Scuba Instructor (OWSI) program. Most dive professionals complete the entire IDC and go on to attend an Instructor Examination (IE), which is the final step to earn a PADI Instructor certification.
Successfully completing just the AI course results in a PADI Assistant Instructor qualification. When an AI is ready to progress, attending an OWSI program allows entry into an IE to earn a full PADI Instructor rating.
Dive professionals who hold an instructor rating with another diver training organization may be eligible to enroll directly in the OWSI program. This recognizes prior instructor training and provides a path to become a PADI Instructor.
A PADI Divemaster who has been a certified diver for six months may enroll in the PADI Instructor Development Course. You also need:
At least 60 logged dives and 100 dives to attend an IE.
