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.
A PADI Divemaster who has not been a certified diver for six months may enroll in the PADI Assistant Instructor Development Course. You also need:
At least 60 logged dives
CPR and First Aid training training within the past 24 months. (Emergency First Response Primary and Secondary Care recommended)
A medical statement signed by a physician within the last 12 months
