PADI Instructor Development Course (IDC) Koh Tao - Course Completion By PADI standards, the IDC itself can be completed in 8 days. This would include, both the Assistant Instructor (AI) and Open Water Scuba Instructor (OWSI), components of the course. From this point you would then need to complete a 2-day Instructor examination (IE) in order to become certified as a PADI OWSI. At IDC Koh Tao we run a 2-week program, which includes: Two full days of Dive theory and Skill Prep Emergency First Responder & Emergency Oxygen Provider Instructor Training A Mock Instructor Examination We truly believe preparation is the key to a successful IE and a successful career within the dive industry. We prefer to take more time in order for our candidates to feel 100% confident in taking that next step and becoming a PADI Professional.
