Which of the following would be categorized as NAUI-sanctioned specialty courses?

• A. All of the Above
• B. Underwater Digital Imaging
• C. Night Diver
• D. Underwater Naturalist

Answer: (A)

The concept being tested is recognizing which courses NAUI officially designates as specialty trainings beyond the Open Water Diver program. NAUI’s specialty courses cover specific skills or interests in a focused way, such as imaging, night diving, or marine life observation.

Underwater Digital Imaging is a NAUI specialty that concentrates on underwater photography and videography techniques. Night Diver teaches safety, planning, and techniques for diving after dark. Underwater Naturalist focuses on identifying and understanding marine life and underwater ecosystems. All of these are distinct, officially recognized NAUI specialty courses, so each one fits the category.

Since every option listed is a NAUI-sanctioned specialty, the best answer is that all of them are NAUI-sanctioned specialty courses.
