DOMAIN 1: NAUI Standards, Ethics & Supervision Ratios (10 Questions)
Sub-Topic: Open Water Instructor-to-Student Ratio 1:8 (2 Questions)
Question 1 (Multiple-Choice)
During an open water training dive at a local quarry, a NAUI Instructor has seven student divers
in the water. An uncertified divemaster offers to assist by supervising two additional students
who arrived late. What is the instructor's correct course of action?
A. Accept the help and divide the group into two teams of four and five
B. Decline the additional students and maintain the 1:8 ratio with only the original seven
C. Allow the divemaster to supervise the two late students independently while the instructor
manages the original seven
D. Postpone the dive for all students until a second certified NAUI Assistant Instructor or
Instructor arrives
Correct Answer: D [CORRECT]
Rationale: The NAUI Standards and Policies Manual mandates a maximum instructor-to-student
supervision ratio of 1:8 in open water for training dives. An uncertified divemaster cannot
independently supervise students, and exceeding the ratio violates standards regardless of
assistance. The instructor must either limit the group to eight students total or secure a second
certified NAUI Assistant Instructor or Instructor to maintain proper supervision ratios.
Question 2 (True/False)
A NAUI Instructor may supervise eight student divers in open water for a training dive provided
that a certified NAUI Assistant Instructor is also present and actively supervising, allowing the
group size to expand to 16 students total.
A. True
B. False
Correct Answer: B [CORRECT]
,Rationale: False. The 1:8 instructor-to-student ratio is a maximum per instructor, not a
cumulative group limit. Each instructor or Assistant Instructor may supervise up to eight
students. While two instructors could supervise up to 16 students, the ratio applies
individually—each supervising instructor must not exceed their own 1:8 limit. The presence of
an Assistant Instructor does not automatically double the allowable group size without proper
assignment of specific students to each supervisor.

Question 3 (Multiple-Choice)
Which of the following is NOT a required element in the NAUI "Training Record" before a
student can be registered for certification in the NAUI system?
A. The instructor's full signature in the designated "Instructor Signature Box"
B. The instructor's NAUI certification card number
C. The student's completed medical history form and liability release
D. A photocopy of the student's driver's license for age verification
Correct Answer: D [CORRECT]
Rationale: The NAUI Training Record requires: (1) the instructor's full signature in the
designated Instructor Signature Box, (2) the instructor's NAUI certification card number, and (3)
the student's completed medical history form and signed liability release. While age verification
is required (minimum 10 years for Junior Scuba Diver, 15 for Scuba Diver), a driver's license
photocopy is not a specific NAUI Training Record requirement. Age can be verified through
other means, and the Training Record focuses on training completion, instructor validation, and
legal documentation.
Question 4 (Multiple-Choice)
A student completes all required confined water and open water dives. The NAUI Instructor
signs the Training Record but forgets to enter their certification card number. What is the
consequence?
A. The student can be certified, but the instructor must submit the number within 30 days
B. The certification is invalid until the card number is added and the record is complete
C. The student receives a temporary card while the number is obtained
D. The Assistant Instructor's number can be substituted
, Correct Answer: B [CORRECT]
Rationale: The instructor's certification card number in the Training Record is a mandatory field
that validates the instructor's authority to issue the certification. Without this number, the
Training Record is incomplete, and the student cannot be properly registered in the NAUI
system. The certification is invalid until the record is fully completed. An incomplete Training
Record exposes the instructor to liability and violates NAUI Standards.
Question 5 (True/False)
The NAUI Training Record must be completed in its entirety, including all required signatures
and documentation, before the student participates in their final open water training dive.
A. True
B. False
Correct Answer: B [CORRECT]
Rationale: False. The Training Record is completed progressively throughout the course. Medical
forms and liability releases are collected before any in-water training begins. Confined water
dive logs are signed after each pool session. Open water dive logs are signed after each training
dive. The final instructor signature and certification card number are added only after ALL
training requirements are completed, including the final open water dive. The record is a living
document that tracks progress, not a pre-dive checklist.

Question 6 (Multiple-Choice)
An adult diver (age 28) completes a NAUI Open Water course while on vacation and needs a
referral to complete certification dives at home. The instructor issues a "Junior Scuba Diver"
temporary card because the referral facility only accepts junior-level certifications. What
violation has occurred?
A. No violation; temporary cards are interchangeable
B. The instructor violated NAUI Standards by issuing a Junior card to an adult diver
C. The instructor violated standards by not completing all dives before issuing any card
D. The referral facility is at fault for only accepting junior certifications
Correct Answer: B [CORRECT]
