A few years ago, I was an ESL teacher at a university in southern China. As an American I remember having a fair amount of confusion when first talking with one of the Chinese teachers at the university, who had been taught with more British English, and kept using the word "invigilate" that I had never heard of.
What word do you use instead? "Exam Administrator"?
I had to look this one up too. I've always called them proctors.
Never heard the word "proctor", in Canada they are always called invigilators.
Not always; I've heard the words used interchangeably at our university.
I use the word "proctor."
Likewise. I mainly use "proctor" for that purpose.
