Tech you need
- A desktop or laptop. Smartphones, tablets and Chromebooks aren’t supported. Linux and 2-in-1 devices like a Surface may have problems.
- The latest Chrome or Firefox. No other browsers work. Having both installed is a good backup.
- A webcam and microphone, allowed in your browser settings.
- Internet of at least 1.5 Mbps download and 2 Mbps upload. A wired connection is best. Avoid public or shared Wi-Fi.
Before you start
- Run the System Check within 6 hours of your test, using the same computer, internet, webcam and room.
- Close Zoom, Teams and other apps, turn off any VPN and browser extensions like Grammarly, and restart your computer.
- Log in at least 30 minutes early.
- Start within 15 minutes of your scheduled time. Late entry isn’t guaranteed, and you may have to reschedule and pay a fee.
What’s allowed on your desk
| Allowed | Not allowed |
|---|---|
| Pen and blank paper | Notes written before the test, on paper or a screen |
| Physical dictionary | Phones and smartwatches |
| Headphones, external keyboard, extra monitor | AI tools of any kind |

Rules during the test
- Take it alone, with no help from anyone, unless you have approved accommodations.
- Keep your webcam on, uncovered and facing you the whole time, even after the video section. Turning it off can invalidate your test.
- Type your answers in real time. Copy and paste is turned off.
- Don’t copy, record or share any test content.
- Breaking the rules can lead to a cancelled score, and Acuity may tell your programs.
