GRE at home vs test center: what to choose and why

You’re ready to book the GRE and ETS is offering two rooms: your own, with a webcam and a proctor watching remotely, or a test center with a locker and someone typing next to you. The two deliver the same test and the same score, so the choice comes down to which room you can control. Below is the tech-risk checklist for testing at home, the proctor rules that actually catch people, and a plain rule for choosing.

A note on sourcing. Everything here about at-home rules comes from ETS’s own at-home testing pages, and ETS has changed its proctoring provider and some procedures over time. Where a detail depends on the current provider, it’s marked [verify], and you should confirm it in your ETS account before test day.

The two rooms, side by side

According to ETS, the GRE General Test at home is the same test as the one delivered at a test center: same sections, same about-1-hour-58-minute length, same on-screen tools including the Quant calculator, same scoring. It’s offered around the clock, seven days a week [verify], and you take it on your own computer with a human proctor monitoring you through your camera and microphone, plus a secure browser that locks down the machine.

At a test center you show up at a scheduled time, store your belongings in a locker, go through identity checks and a security screening, and sit at a workstation the center owns. Scratch paper is provided. The environment is controlled by someone else, which is the point. Same test, two risk profiles.

The at-home tech-risk checklist

Most at-home problems are preventable and most of them happen to people who checked the requirements once, weeks before, and assumed. Run this list the week before and again the night before.

• Computer. A desktop or laptop running a supported version of Windows or macOS. Tablets and phones are not permitted; Chromebooks are not supported [verify]. If the machine is managed by your employer, assume the secure browser install or the software-disabling step will fail, and don’t gamble on it.
• Secure browser. Download and install ETS’s secure browser in advance and run its system check. Do it on the exact machine and user account you’ll test from.
• Camera. It must be able to show the proctor a full 360-degree view of the room, including under the desk, which means either a laptop you can pick up and turn or an external webcam on a cable long enough to move. A fixed monitor camera is a problem.
• Audio. A working speaker and microphone. No headphones, no earbuds, no headset of any kind; ETS prohibits them during the session.
• Internet. Wired if at all possible. If you must use Wi-Fi, be close to the router and ask everyone else in the household to stay off video for two hours.
• Power. Laptop plugged in, and the charger checked. A battery that dies at question 20 of Quant ends the test.
• Software. Disable screen-sharing and remote-access tools before you start (that includes corporate remote-desktop clients and some chat apps’ screen-share features). Pause operating-system updates for the day. Close everything else.
• Screen check. ETS may ask you to show your screen and keyboard to the proctor during check-in, typically with a hand mirror or your phone held up to the camera; have one on the desk and confirm the current method in your ETS account [verify].
• Note-taking surface. A small whiteboard with an erasable marker, or blank paper inside a transparent sheet protector written on with an erasable marker. Not loose paper, not a notebook, not a pen. Have a cloth to erase with.
• Identity. Complete any pre-test identity verification steps ETS requires in your account well in advance; some steps have deadlines days before the session [verify], and the ID you show on camera must be the one that matches your registration.

Do all of it twice. Once a week out, once the night before.

The room rules that trip people

ETS’s at-home environment rules are short, and nearly every rule violation we hear about involves one of them. You must be alone in the room for the entire session; another person entering, even briefly, can end the test. The room must be quiet, well lit, and indoors; outdoor and public spaces aren’t allowed. Your computer sits on a desk or table and you sit in a standard chair, not a bed, couch or floor. The table and the area around it must be clear. And your chair and table must be positioned so that the door to the room is visible to the proctor through your camera.

That last one surprises people. It means you may need to rearrange furniture so that the camera sees both you and the door, and it means a desk facing a wall with the door behind you won’t pass. Set the room up a week early and run a practice test in it exactly as configured.

Then the rules that apply to you rather than the room. No headphones or earbuds. No face mask during check-in or testing, per ETS. No leaving your seat or the camera’s view at any point, since the current GRE has no scheduled break and ETS prohibits unscheduled ones. No talking or reading aloud; proctors are instructed to watch for it, and mouthing text completion sentences to yourself is a habit to break in practice. At the end, the proctor asks you to erase your whiteboard or sheet protector and hold it up to the camera, front and back, before the session closes. Quiet room, visible door, empty desk.

The test-center risks, for balance

Centers remove the technology from your list and add logistics. Arrive late and you may be turned away; most people should plan to be at the door 30 minutes before the appointment, with the parking and the drive already rehearsed. Your ID must match your registration exactly. You’ll empty your pockets, and anything you want during the test (a jacket, tissues) may be subject to inspection. The room will contain other people, some of them typing essays while you’re doing Quant, and you don’t get to choose your seat.

Center availability also varies by city and season. In busy application months the slot you want may be weeks out, which can matter when a deadline is close. Book early. None of those risks is as sharp as a dropped internet connection, but they’re real, and they favor people who are organized about logistics over people who are organized about technology.

How to choose

The decision isn’t about which is easier. It’s about which room you can actually control.

Choose home if all of the following hold: you have a private room you can keep empty and silent for the full session, including the check-in window; you own and administer a Windows or Mac computer that passed the secure browser’s system check; your internet is wired or reliably strong; your camera can show the whole room; and you’ve taken at least two full practice tests in that exact room, at that desk, with the door in view and a whiteboard in hand. All five, not most.

Choose a center if any of these hold: you share walls or a household you can’t silence; your only computer is a work machine; you’ve had any proctored session interrupted before by technology or by another person; you’re testing within a few weeks of a hard deadline and can’t afford a voided session; or the idea of being watched through your own webcam for two hours is going to cost you points by itself. If you’re genuinely split, choose the center for the deadline that matters most and home for a later attempt if you need one.

Practicing in the room you’ll test in

Whichever you choose, your Sunday practice sittings should match it. At-home testers should sit every practice test at the test desk, door in view, laptop plugged in, whiteboard instead of paper, phone in another room, for the full timed run with no breaks. The whiteboard matters more than it sounds: working Quant on an erasable surface the size of a sheet of paper is a different skill from working it on a legal pad, and the first time you run out of space shouldn’t be on test day. Center testers should practice with earplugs out and some background noise on, since centers don’t guarantee silence, and should do at least one practice test after driving somewhere and sitting down cold, the way test day will go.

A week before the real session, at-home testers should also run the full check-in sequence as a drill: install check, room scan with the camera, show the desk and the whiteboard, erase and show both sides. Fifteen minutes. It removes the last unknown.

Rick’s note: Most of the test-day problems I’ve seen with the at-home GRE were foreseeable a week out: a laptop camera that couldn’t show the floor, a work machine that wouldn’t take the secure browser, a desk facing the wrong way. The students who had none of them were the ones who had already taken two practice tests in the real setup. The room is part of the test. Rehearse it like one.

What to do this week

1. Decide which room, using the two lists above, and write the reason down in one sentence.
2. If home: install ETS’s secure browser on your test machine, run the system check, and rearrange the desk so the door is in the camera’s view.
3. If home: buy a small whiteboard and erasable markers (or sheet protectors) and use them on every practice test from now on.
4. If a center: book the slot now, drive the route once at the same time of day, and check that your ID matches your ETS registration exactly.
5. Read ETS’s current at-home test day page in your account and note any identity-verification step with a deadline before the session.
