Specialty Instructor & Advanced Open Water Instructor Teaching specialty courses is a perfect way to continue growing as an SSI Instructor. Specialty courses offer variety and are convenient and easy to learn. Also, you get to teach the activities you love most! Instructors may qualify to teach specialty courses by attending one of SSI's seminars, co-teaching with an Advanced Open Water Instructor or by documenting significant experience. Instructors must also purchase the course teaching materials for the particular specialty they wish to teach. And when an Instructor is qualified to teach four or more specialties, they earn the Advanced Open Water Instructor rating.
