Open Water Scuba Instructor
(Instructor Development Course)
The PADI Open Water Scuba Instructor (OWSI) course is the professional-level training that teaches you to teach PADI courses, forming the second part of the Instructor Development Course (IDC), alongside the Assistant Instructor (AI) course.
Are you ready to join the ranks of the dedicated professionals who teach the world's most progressive and popular scuba diver education programs? Then Go PRO with an Instructor Development Course.
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.
​
Over a minimum of 5 days, but we do it over 10 days to allow more preparations and training. The IDC teaches you to conduct all PADI core courses. You'll be able to organize and present information, conduct skill development sessions and control open water dives. Basically, you become a better public speaker and get really good at demonstrating skills while watching out for student diver safety. Key topics include:
-
PADI Standards and Procedures for courses you can teach with in-water workshops
-
Learning, Instruction and the PADI System
-
Risk Management and Diver Safety
-
The Business of Diving and your role as an instructor
-
Marketing Diving and Sales Counseling

-
At least 100 dives to attend an IE.
