Snorkeling Instructor Course
The ITDA-IHMP Snorkeling Instructor course qualifies certified professionals (Dive Leader, Open Water Scuba Instructor or above) to teach, supervise and certify the ITDA Snorkeling program. You will learn how to plan sessions, fit and care for snorkeling equipment, teach breathing and clearing skills, control groups in open water, and run a safe, standards-based assessment. The course follows the same three-part structure as the Learn to Swim Instructor course: professional duties, teaching technique, and safety and assessment. Every module finishes with a knowledge quiz, and the practical assessment is completed with an ITDA-IHMP Authorized Professional so your certification is issued against verified in-water competence. Graduates can deliver the entry-level Snorkeling course independently, run club snorkeling sessions, and use snorkeling as a confidence-building step in the Learn to Swim and Open Water Scuba pathways.
