At Home Testing

Taking a GRE Subject Test at home is a safe and convenient option for test takers who prefer to take their test at home rather than at a test center. At home testing is offered in most locations around the world.

The at home test is identical to a test taken at a test center and taken on your own computer at home or another secure location. All at home tests are monitored by a human proctor online through ProctorU®. At home testing is available on certain dates in September, October and April as soon as 24 hours after you register.

Equipment and environment requirements

To take a test at home, your computer and testing room must meet the requirements outlined below. If they don’t, you won't be able to test and you won't receive a refund or a free reschedule.

  • Run the ProctorU Equipment Check from the computer you will use for the test. If you fail the equipment check, you must fix any issues before test day. Live ProctorU representatives are available to help.
  • Computer firewalls and security applications can interfere with the test delivery software. If you experience this issue, you may need to disable or reconfigure your applications prior to the test.


Helpful Tip

The equipment check includes a bandwidth check. Since bandwidth differs depending on time of day and network usage, run the equipment check at a few different times to see which time works best. Additionally, be sure to run it at a time and in an environment similar to what you would experience when you test (e.g., your entire family is home and on their phones, other devices, etc.).
