How to master the Duolingo English Test at Home

A successful Duolingo English Test depends on having the right tools ready. The DET requires a computer with stable internet, a front-facing camera, microphone, speakers, and the desktop app. 

Crucially, the introduction of a secondary camera, such as your smartphone, adds an extra layer of security and transparency.

Your secondary camera needs to be connected to Wi-Fi and fully charged or plugged in. Position it behind you on a stable surface, providing a panoramic view of your test area.

Once in position, link your phone using the QR code provided in the DET app for a secure, hands-free connection.

To avoid surprises on your Duolingo English Test test day, utilise the system check tool on the official DET website a day or two before your scheduled exam. This tool will verify:

• Internet speed and reliability
• Computer audio and video functionality
• The app version is up to date
• Secondary camera connectivity

For extra peace of mind, restart your computer and close unnecessary applications before your exam begins.
 

Security is paramount in the Duolingo English Test. Before you begin, you’ll be prompted to conduct a room scan and ear scan with your secondary camera. 

The room scan confirms your workspace is free from unauthorised items, while the ear scan ensures you’re not using earbuds or hidden audio devices. Both checks are straightforward, helping to maintain fairness across all candidates.
 

Your desk should only contain what’s strictly necessary: your computer, identification, and phone acting as your secondary camera. 

Remove any books, papers, headphones, or additional electronics to speed up the room scan and prevent certification issues. 

Position your phone at shoulder height behind you, ensuring your face, screen, and hands are always visible.

Both cameras must capture your face clearly. Use natural daylight wherever possible, or place lamps directly in front of you. 

Keep your computer’s camera at eye level and check the secondary camera’s stability before starting. Using a stand can help with this.
 

Your physical setup is important, but so is your mindset. Take deep breaths beforehand, silence all notifications, and familiarise yourself with the process. 

You’re allowed brief pauses if needed, but must remain seated and focused. Practising in your full at-home English test setup the day before is highly recommended, as it’s the most effective way to build confidence and ensure readiness.
 

The Duolingo English Test uses AI and human proctors to review your performance. Abiding by the guidelines ensures your results are validated quickly:

• Remain alone throughout the test.
• Avoid using earbuds, headphones, or other audio devices.
• Your face, hands, and keyboard must be visible to both cameras.
• Do not move or touch your phone once it’s set as the secondary camera.
• Refrain from speaking, reading aloud, or leaving the camera view.

Follow these steps and you’re primed for a successful test day. The DET’s innovative features – including the Duolingo English Test secondary camera, room scan, and ear scan – ensure you’re able to take your test securely and showcase your skills as fully as possible.
