The GRE at home and the GRE at a test center are the same test. Same content, same section structure, same scoring algorithm, same score scale. When your scores arrive at a program, there is no field indicating which format you used. Admissions committees do not distinguish between them.
The decision comes down to your environment, your equipment, and how you perform under different conditions.
What Is Actually Different
Scratch paper. At a test center, the facility provides scratch paper. You can request more by turning in your used sheets. At home, you use either a whiteboard with a dry-erase marker or paper inside a transparent protector. You cannot use regular loose paper. For Quant-heavy test takers who go through a lot of scratch work, this is the most practically significant difference.
Proctoring. Test centers use in-person staff who check your ID, monitor the room, and handle any issues during the test. At home, a human proctor monitors you via webcam throughout the session. They can hear and see you. You cannot speak unless spoken to, and you cannot look away from the screen for extended periods.
Second camera requirement. Since January 5, 2026, at-home testing requires a second camera device, typically a smartphone, to show the proctor a 360-degree view of your testing area before the test begins. Test centers have no such requirement.
IDVaaS verification. For at-home tests booked after March 31, 2026, ETS requires you to complete identity verification through the IDVaaS app 72 hours before your test. You will receive instructions after booking. Missing this step means you cannot test. Test centers handle ID verification on-site at check-in.
Scheduling flexibility. At-home slots are available 24 hours a day, seven days a week. If you want to test at 6 AM on a Saturday or 10 PM on a Tuesday, you can. Test centers operate during business hours and have limited seats. In markets with few test centers, at-home may be your only realistic option for a specific date.
Your environment vs. a controlled one. At a test center, the facility manages distractions. At home, you do. If your living situation has noise, interruptions, or a roommate who does not respect a "do not disturb" request, test center performance will likely be better.
Technical Requirements for At-Home
These are non-negotiable. If your setup does not meet them, you cannot test at home.
- Windows 11 or newer, OR Mac OS 11 or newer
- Chrome browser (not Safari, not Firefox, not Edge)
- Desktop or laptop only. No tablets, no Chromebooks, no iPads.
- Single monitor. A second external display connected to your machine is not allowed.
- Internal or external speaker. No headsets.
- Internal or external microphone. It cannot be part of a headset.
- Moveable camera capable of a 360-degree room scan
- Second camera device (smartphone) as of January 5, 2026
- Stable internet connection
Run through this list before paying. If you have a Chromebook or rely on a tablet, at-home is not available to you.
The Testing Environment at Home
ETS has strict rules about the physical space.
Your testing area must be private and quiet. No other people are allowed in the room. Your desk must be clear of everything except your scratch material (whiteboard or transparent protector with paper) and your computer. No phones, no notes, no food or drink during the test.
The proctor will ask you to do a 360-degree room scan before the test begins using your second camera. They are checking for prohibited materials. If anything in the scan raises a flag, they can terminate your session before it starts.
During the test, you must remain visible on camera. You cannot put your head down, cover your mouth, look away from the screen for extended periods, or leave without proctor permission. ETS publishes a detailed list of rules that you review and agree to before each at-home session.
What Test Centers Look Like
At a test center, you arrive 15 to 30 minutes before your appointment. You present your ID, go through check-in, store all personal items in a locker, and are escorted to a testing station. The facility provides scratch paper. You can request additional scratch paper during the test by turning in what you have.
If you need to access food or medication, you can request to go to your locker. You cannot bring anything into the testing room. Phones, watches, and all personal electronics must be in the locker. In most centers, you work at a computer with dividers between stations. Noise-canceling headphones may be offered (not required).
If a technical issue occurs, staff are present to address it.
Which Format Performs Better
There is no meaningful data showing that one format produces better scores than the other. Perform well and your score reflects your preparation, not your environment choice, as long as that environment is controlled.
Where at-home tends to go wrong: technical failures mid-test, proctor disconnections, violations triggered by ambient noise or a roommate walking through the background, and scratch paper limitations that interrupt working style.
Where test centers tend to go wrong: anxiety in an unfamiliar room, noise from other test takers, and commute-related stress on test day.
If you want to simulate the real test accurately before deciding, take a full-length practice test at home under at-home conditions. Notice whether the setup feels controlled or chaotic. The GRE mock exams on this platform are timed and full-length, which gives you a realistic read on how you handle a 2-hour session in your current environment.
Making the Call
Choose at-home if:
- Your home environment is genuinely quiet and private
- Your equipment meets every technical requirement
- You want maximum scheduling flexibility
- No convenient test center exists within reasonable distance
- You perform better without strangers in the room
Choose a test center if:
- Your home has unreliable internet, noise, or frequent interruptions
- You do not have the required equipment setup
- You want scratch paper without the whiteboard constraint
- You perform better in structured, managed environments
- You want in-person support if something goes wrong
Either way, take the GRE diagnostic before you book anything. Your baseline score will tell you how much prep time you need, which determines how far out to schedule your test date, which in turn shapes which format has available slots when you are ready.
