The NAUI Divemaster rating is the highest NAUI leadership level certification with the exception of Instructor. The program is designed to train experienced and knowledgeable divers to organize and conduct enjoyable open water dives for certified divers and engage in other approved activities.
An active-status NAUI Divemaster is qualified to organize and conduct dives for certified divers if the diving activities and locale approximate those in which the Divemaster is trained. Additional training, knowledge or experience is necessary for the Divemaster who desires to organize dives in a new locale.
An active-status NAUI Divemaster is qualified to organize and conduct NAUI recognition programs (such as International Diver) and award appropriate recognition materials to participants. An active-status NAUI Divemaster is qualified to organize and conduct Refresher Scuba training for certified divers. Additionally, NAUI Divemasters may teach the NAUI Try Scuba (confined water only), and the NAUI Skin Diver courses. An active-status NAUI Divemaster is qualified to assist an active-status NAUI Instructor in diving courses.
An active-status NAUI Divemaster who completes all requirements as laid out by the NAUI Training Department, is eligible to teach the NAUI First Aid – Powered by DAN provider courses.
An active-status NAUI Divemaster who possesses exceptional abilities, experience and completes all requirements as laid out by the NAUI Training Department, may teach the Underwater Archaeology, Underwater Digital Imaging, Underwater Hunter and Collector, and Underwater Naturalist courses.

INSTRUCTION
Teaching Techniques, including class management, teaching theory and oral communication as it relates to Skin Diving, Try Scuba and approved specialties shall be included.
Divemastering. Students are to demonstrate satisfactory open water skills and perform in Divemaster roles for practice and evaluation during the planning and conducting of the required open water dives. All such activities are to be performed under the direct supervision of an active-status NAUI Instructor. The purpose is to evaluate the candidate in both knowledge and the ability to apply it in the performance of practical work. The evaluated activities also further the student Divemaster’s training in dive management.
Perform scuba diving skills as listed below during an open water dive. The staff is also to use this dive to demonstrate the organization and conduct of a day dive for certified divers. Skills are to include:
Pre-dive gear check for self and buddy.
Entry, buoyancy check, swim to and from dive area, and exit.
Distance swim -805m (880 yards) total during the dive.
Descents, underwater swimming, and ascents.
Make a simulated decompression stop at 4.6m (15 ft.) for five minutes.
Mask clearing, including removal and replacement.
Remove, replace and clear a regulator.
Regain primary regulator from behind the shoulder; replace and clear.
Maintain proper buoyancy using weights, breathing, and BC.
Complete a night dive as a diver. During this dive, the staff will demonstrate the organization and conduct of a night dive for certified divers. The dive is to be conducted in an area previously dived by the class during daylight.
Performing as a Divemaster using safety divers and assistants, control a satisfactory rescue of a diver simulating an underwater accident in open water, including organizing a search, transporting victim to shore or boat, victim care and accessing emergency systems.
Prepare and present at least one pre-dive briefing for practice and one for evaluation. The briefing is to be evaluated on depth of coverage as well as safety and control measures. Evaluators are to remember the student is not an instructor and may not possess polished instructional skills.
Performing as a Divemaster, assisting an active-status NAUI Instructor, organize, and assist during an early open water experience for a class of student divers.

Performing as a Divemaster, organize and conduct a beach dive for certified divers, to be evaluated for the record.
Performing as a Divemaster, organize and conduct a boat dive for certified divers, to be evaluated for the record. If a boat dive is not possible, an alternate beach dive in a significantly different setting from that of the previous dive is allowed.
Organize and conduct a night or limited visibility dive for certified divers, to be evaluated for the record. If night diving is not possible, a simulation should be utilized.
Perform as a Divemaster conducting a NAUI Try Scuba, NAUI Refresher and NAUI Skin Diver course
The student Divemasters may run multiple dives on the same day up to a maximum of three scuba dives and one skin dive. The greatest possible variety of diving situations should be used.
