Which of the following is a type of knowledge item commonly included in a PQS?

• A. Leadership skills
• B. Foreign language proficiency
• C. Technical fundamentals
• D. Physical fitness tests

Answer: (C)

The main concept tested is how a PQS organizes tasks into knowledge items versus hands-on performance items, with knowledge items representing understanding of basic principles and fundamentals rather than doing a task. In a PQS, knowing the technical fundamentals means grasping how a system operates, its major components, how they interact, typical operating principles, safety considerations, and the procedures that govern proper use. This kind of knowledge is what you must understand to diagnose issues, plan maintenance, and apply correct methods before actually performing the task.

Technical fundamentals fit this role precisely because it’s about the theory and baseline understanding underlying equipment and procedures. It isn’t about executing a task (which would be covered by performance items) and it isn’t about broader skills like leadership, language ability, or fitness tests, which are outside the standard focus of PQS knowledge items.
