What is the maximum supervisory ratio recommended in the Coast Guard?

• A. 1:4
• B. 1:7
• C. 1:15
• D. 1:10

Answer: (C)

Span of control is about how many people a supervisor can effectively oversee at once. In Coast Guard practice, the recommended maximum is one supervisor for every fifteen personnel. This keeps supervision practical enough to maintain clear communication, provide timely feedback, and monitor safety and performance, even in busier or higher-risk settings. If you try to supervise too many people, the supervisor’s ability to notice issues, coordinate actions, and mentor subordinates drops, increasing the chance of errors or unsafe situations. Keeping the ratio at or below this level balances efficient leadership with hands-on oversight. While some tasks may operate with smaller teams under tighter supervision, the standard upper limit stays at fifteen subordinates per supervisor.
