an invigilator; a proctor
I didn't know he was the proctor this week.
The proctor caught him cheating in the maths exam.
Just then the proctor informs you that the time is up.
You can't simply ask the test proctor for a new essay question.
For the first hour I sat there waiting anxiously for the proctor to give out the paper.
Ih the Qing Dynasty, Chen Lanbin, the first proctor of Chinese students studying abroad and the first China's envoy in U.
He and the proctor capped each other as they met, as if they were rival powers, and the man hardly knew which was the Greater.
