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.
