The National Association of Underwater Instructors (NAUI Worldwide) has been teaching the world to dive safely since 1959. As the oldest, second largest and most respected dive training and certifying organization in the world, NAUI offers a full range of training programs from Skin Diver through Instructor Course Director, with dozens of specialty courses including Nitrox and Technical diving.

NAUI’s global reputation for the best in training and educational products reflects its core values of quality dive training through education. Many organizations specifically choose NAUI for their diver education programs including Walt Disney World Resort in Orlando, Florida, United States Navy SEAL Teams and NASA’s Neutral Buoyancy Laboratory in Houston, Texas (USA) where astronauts train for their space walks.

While NAUI has long been respected for having the highest training standards in the recreational diving industry, we are also highly regarded for our Technical Diver Training. Many of our technical developments have been adopted by other agencies; our Technical Diving Division continues to produce new theories and research that keep NAUI on the cutting edge of technical diving.

NAUI Worldwide is a membership organization headquartered in Tampa, Florida (USA) with tens of thousands of member instructors, affiliated stores, resorts, and service centers located in countries throughout the world. With tens of thousands of dive professionals and numerous affiliated dive training centers in nations around the globe, we have over one-third (and growing) of the US market with an even larger market share internationally.
