All instruction must be carried out, or supervised by, a qualified instructor
Full details of instructor requirements are contained in the Instructor Manuals (IM) for each element of the Diver Training Programme (DTP). This information is also summarised in the supervision and instructor matrix.
The minimum grade to supervise Assistant Diving Instructors (ADI), or Assistant Open Water Instructors (AOWI) is BSAC Open Water Instructor (OWI).
Club Instructor is a pre-2002 instructor qualification. They are permitted to teach open water lessons to their diver qualification without the need for another qualified instructor to be present but may not supervise ADI or AOWI during open water training.
