Examinations are supervised by "invigilators" in the UK and "proctors" (or "(exam) supervisors") in the US (a "proctor" in the UK is an official responsible for student discipline at the University of Oxford or Cambridge). In the UK a teacher first "sets" and then "administers" exam, while in the US, a teacher first "writes", "makes", "prepares", etc. and then "gives" an exam. With the same basic meaning of the latter idea but with a more formal or official connotation, a teacher in the US may also "administer" or "proctor" an exam.
