What is the maximum number of students that one active-status NAUI Instructor can manage in confined water with one Assistant Instructor in training?

The correct answer is 16, which reflects the guidelines set by various diving organizations, including NAUI, regarding instructor-to-student ratios in confined water settings. When an active-status NAUI Instructor is supported by one Assistant Instructor in training, they can effectively manage a larger group of students due to the additional oversight and instructional support provided by the Assistant Instructor. This arrangement increases safety and facilitates more effective learning, allowing for a maximum of 16 students in such a setting.

Understanding the rationale behind instructor-to-student ratios is crucial for maintaining safety and ensuring quality instruction. The established limits are designed to ensure that each student receives adequate attention and instruction while also considering the safety of participants in controlled environments.
