Which of the following is a typical example of a collateral duty?

• A. Safety petty officer
• B. Maintenance supervisor
• C. Quality Assurance Officer
• D. Training NCO

Answer: (C)

Collateral duties are secondary responsibilities assigned in addition to a sailor’s primary job to support essential programs. A Quality Assurance Officer fits this role because QA is a cross-cutting function that verifies work meets standards, conducts audits, tracks deficiencies, and drives corrective actions across the command. Because QA spans multiple tasks and departments, it’s commonly designated as a collateral duty—a supplemental responsibility that sits alongside the main rating duties. In contrast, a maintenance supervisor is typically the primary supervisory role within maintenance, and a Training NCO is usually tied to core training duties; while a safety petty officer is also a known collateral duty in many commands, the QA Officer example best embodies the typical collateral-duty concept as it centers on program-wide quality oversight.
