Department Support for Proctoring
This option allows faculty to be available if questions arise during the exam without having to proctor the exam themself. Admin staff, GAs/TAs, or colleagues in the department can proctor an exam.
Another option is for the student to take the exam in a secure location, such as a conference room, or empty faculty office where someone can check in from time to time.
Your department scheduler can assist in finding a suitable space (conference room, classroom, etc.) for testing.
