What is the purpose of PQS?

• A. A program that trains for watches or duties necessary for the safe operation of the ship.
• B. A catalog of all shipboard responsibilities.
• C. A timetable for leave rotations.
• D. A glossary of naval terms.

Answer: (A)

PQS is a program that certifies sailors are qualified for watches and duties necessary for the ship to operate safely. It provides a structured set of tasks and knowledge for each watch station or system, with clear steps to demonstrate competence and a sign-off by a qualified supervisor. This qualification framework ensures everyone on duty can perform their responsibilities correctly and consistently, reducing risk during operations. The other options describe things PQS isn’t—it's not simply a catalog of duties, a leave timetable, or a glossary of terms.
