What constitutes a valid PQS sign-off?

• A. A trainee signs off after completing the task on their own without observation.
• B. A peer reviewer signs off after observing the task.
• C. A qualified supervisor or designated examiner observes the task or knowledge check and signs off in the record with the date and their status.
• D. Sign-offs are not required for PQS tasks; only knowledge checks require sign-off.

Answer: (C)

A valid PQS sign-off happens when a qualified supervisor or designated examiner directly observes the trainee performing the task or completing a knowledge check and signs the record with the date and their status. This external verification confirms the trainee met the required standard for that task or knowledge area and creates a dated, accountable record of progress. The sign-off cannot be done by the trainee themselves, and while observation by others can occur, the authority to certify rests with a supervisor or designated examiner who is qualified to assess and approve the outcome. Sign-offs apply to both hands-on tasks and knowledge checks, ensuring clear documentation of who signed, when, and under what authority.
