Assistant Instructor

Assistant Instructor

Assistant Instructor certification is the second required step in the development toward becoming an SEI Diving Instructor.

Assistant Instructors may teach the SEI Diving Snorkeling for Families Course. During the Open Water Diver course, Assistant Instructors may be used in all aspects of classroom and pool or confined water training under the supervision of an SEI Diving Instructor.

However, an Instructor must evaluate all skills. During open water training for Open Water Diver, the Assistant Instructor may conduct tours only after all skill evaluation and the first dive has been completed by the Instructor. The emphasis of the Assistant Instructor program is to show the participants how and what to teach once they become an Instructor.

The Assistant Instructor course requires at least 23 hours. Certification renewal is required annually and liability insurance for Assistant Instructors is recommended but not required.
