Most students qualify to take the proctored GRE online at home, provided they can meet equipment and test space requirements. At-home testing requirements include a desktop or laptop computer (no Chromebooks or tablets) with a licensed, approved operating system and a Firefox or Chrome browser. Computers must also have working cameras, microphones, and speakers.

Test-takers must take their GRE alone, at a desk, and in a room with doors closed. You're also required to dress appropriately and keep your ears and face visible during the test.
