Proctors through our proctoring service ProctorU cannot secretly access your computer files. With your permission, proctors have the ability to view your screen and utilize the mouse and keyboard as if they were sitting next to you.
Once the exam starts, the proctor will monitor everything on the screen, but can no longer use your mouse and keyboard. During the entire process, a chat box is running, and you can see what permissions the proctor currently has at any time.
The entire chat is saved, including a record of what actions the proctor took while accessing your computer.
