The SDI Divemaster Course is the first professional level certification. During the course you will learn how to work with divers, lead certified divers, and act as a dive guide showing divers underwater dive sites and the marine life that inhabits those dives sites. You will increase your knowledge about physics and physiology as well as increase your proficiency with your scuba and snorkeling skills.
The SDI Assistant Instructor Course is designed to build on the SDI Divemaster Program by gaining practical teaching experience, learning to prepare lesson plans, and give academic presentations. You will work with an instructor to gain experience teaching before moving on to the SDI Open Water Scuba Diver Instructor level. Once you complete the Specialty Instructor training with a qualified SDI Instructor Trainer, you can become qualified to teach several SDI Specialty Diver courses.
