What is Peer Checking?

• A. Having a colleague ensure your work is correct.
• B. Self-check only.
• C. Supervisory audit after task.
• D. Final performance review.

Answer: (D)

Peer checking is when a coworker reviews another person's work to verify accuracy and safety before the task is considered complete. The idea is to have a fresh set of eyes examine calculations, diagrams, labels, and procedural steps to catch mistakes that the original person might miss and to ensure everything aligns with established standards. This collaborative check helps prevent errors that could lead to outages, safety incidents, or noncompliance by providing an extra layer of verification.

It’s not the same as doing a self-check, where the individual is left to review their own work alone; nor is it a supervisory audit conducted after the task is finished, which is a separate formal review by a supervisor; and it’s not a final performance evaluation, which assesses overall performance over a period of time rather than the accuracy of a specific task.
