SDI IDC - Become a scuba diving instructor

The SDI Instructor Development Course focuses on learning how to teach, not perfecting your skills. If you need to polish or fine-tune your own dive skills before starting the IDC, contact your course directly to follow a preparation course or some mentoring sessions. Your diving skills should already be excellent as your knowledge of diving equipment, physics, and physiology. During the SDI IDC, you’ll learn how to share your knowledge and experience with others.

  • SDI’s philosophy 
  • Learn teaching methodologies and instructional techniques.
  • Give classroom presentations
  • Enhance your knowledge of diving equipment, physics, and physiology
  • Gain confidence in conducting classroom and water sessions (confined water in a pool or pool-like environment and open-water sessions).
  • Develop risk management skills
  • Marketing strategies for yourself as an SDI Instructor
  • Undergo evaluation by SDI Instructor Evaluators
  • Demonstrate proficiency in teaching and safety protocols
  • Obtain SDI Instructor certification

By the end of your SDI IDC, your will have the essential knowledge, skills and confidence to train scuba divers through all of SDI’s core recreational level courses and several specialties.

Complete the SDI IDC in just 10-14 days and start your dive career journey. Flexible scheduling options are available to accommodate your needs.

Check out the dates with your IDC Center, some might offer a consecutive program, others might be flexible.
If you prefer to take your time, your IDC Center might schedule scuba diving instructor training over several weekends, accomodate a training schedule for you.

Different parts of the IDC will feel easy and others more challenging. For example, classroom presentations might be easier for you if you are already comfortable speaking in front of people. And the SDI’s Instructor Manual outlines everything you need to say. Others might feel nervous and have a hard time. Meanwhile, you might stress out about the rescue exercise while other candidates perform it effortlessly.

When starting your IDC less than a year after becoming a Divemaster, your skills are sharp but you might have forgotten some of the dive theory (oops!). 

For IDC students who havn’t been active Divemasters for years, the learning curve migt be steeper. The good news is that SDI is known for its high-quality instructional curriculum that accommodates students with different learning styles at various levels. It’s one of the main reasons most dive instructors are SDI Instructors. Furthermore, SDI’s Instructor Trainers (Course Directors) are some of the most experienced and elite Scuba Diving Instructors. 

  • By choosing SDI, you set yourself up for success.
  • If you became a Divemaster while ago or haven’t assisted classes, tell your Course Director. They might offer an IDC preparation course or recommend ways to prepare for the IDC through mentoring.
