Why become an Instructor Trainer
As an Instructor Trainer, you have reached the top of the food chain in the Scuba diving world. You are able to train instructors, assist / Course Director Workshops, and conduct crossover programs for diving professionals. After successfully completing the ITW, you may qualify as an Instructor Trainer for TDI and ERDI courses as you build experience teaching at those levels without needing to attend another ITW. As an Instructor Trainer, you will also have the ability to expand your dive center’s instructor base as well as increase revenue.
