What does invigilator mean?
An invigilator is a person who supervises candidates during an examination or test. The role involves distributing or checking papers, monitoring the room, answering procedural questions, and ensuring that the examination rules are followed. In British English, invigilator is the usual term, while American English more often uses proctor. The word can also refer more broadly to someone who watches over an activity, though its established modern use is chiefly in education. Invigilator comes from the Latin invigilare, meaning “to watch over” or “keep watch,” and it shares its root with vigilant and vigilance. The term is useful because it identifies a specific supervisory role rather than merely a general overseer, particularly in settings where fairness, security, and consistent testing conditions are important.
