Assistant Instructor ISO 24802-1



The Assistant Instructor class provides a gateway to the world of dive instruction. In this class the diver

receives the basic tools for conducting a dive briefing, and is certified to perform refresher dives and

introduction dives within a dive shop or dive club.

The TIDF Assistant Instructor rating is unique in that in addition to certifying the Assistant Instructor to

perform refresher and introduction dives, the Assistant Instructor is also certified to carry out the in-water

modules of the TIDF Two Star (Advanced Open Water) class.
