The Duolingo English Test (DET) is known for its flexible, home-based examination format, but with that convenience comes an ever-evolving responsibility for test security and fairness. If you’re preparing for the DET in 2025 or advising someone who is, there’s a critical update you cannot afford to miss: a brand new room scan protocol, effective immediately (introduced just two days ago). We’re breaking down what’s changed, why it matters, how to ace the new requirements, and how you can adapt your preparation right now.
Why Did the DET Room Scan Update Happen?
The integrity of remote exams like the Duolingo English Test depends on strong security measures. Over the years, incidents of unauthorized device use during home exams prompted DET to take additional precautions. With the explosion of smart devices-phones, tablets, smartwatches-traditional webcam-based scans became much easier to exploit.
DET’s 2025 update tightens the rules considerably by making 360-degree mobile room scans mandatory before you even begin your test. This isn’t just a minor tweak; it’s a significant shift in how DET will verify your environment and protect the value of every student’s score.
How the New 2025 DET Room Scan Works: Step-by-Step
If you’re testing on or after this date, you should expect a more rigorous process compared to previous years. Here’s what you’ll experience as a test-taker:
- Prepare Your Space: Start by removing all unauthorized items-cell phones, extra tablets, smartwatches, earpieces, or any auxiliary screens. Even reflective surfaces or clutter that could hide devices should be cleared away.
- Get Your Phone Ready: Your phone is now a required part of the process. It must have a functional camera and sufficient charge. Ideally, connect it to stable Wi-Fi.
- Scan the QR Code on Your DET Dashboard: When you begin your DET attempt on your computer, you’ll be prompted to scan a QR code with your mobile phone. This securely links your room scan video with your exam session.
- Perform a 360° Video Scan: Use your phone to slowly pan around your entire testing room.
- Review and Submit: Follow the on-screen instructions to review your video and submit it. You may be asked to rescan if any section is unclear or improperly shown.
Essential Room Scan Tips for DET Candidates
- Lighting is key: Poor lighting can cause rejections. Use lamps or sunlight so all corners are visible.
- Move slowly and deliberately: Fast movements look blurry and might skip details. A slow, steady pan improves clarity.
- Avoid mirrors and reflections: Reflections may inadvertently show hidden items or create confusion for the reviewer.
- Rescans are common: Don’t panic if you’re asked to repeat the scan-carefully address any missed area or item that seemed unclear.
- Keep your phone charged: If possible, have your mobile plugged into a charger during setup to avoid interruptions.
Frequently Asked Questions About the New Room Scan
- Can I take the test without a phone for the scan?
No. A recent-model phone with a working camera is now required. The web camera on your laptop is no longer accepted for the room scan requirement. - What if I have an unusual room setup or accessibility concern?
Reach out to DET support ahead of time for approval or guidance. Better safe than sorry! - Will my actual test get cancelled if I fail the scan?
If you cannot provide a clear, compliant scan, you will not be able to begin the exam. If you bypass instructions or have visible unauthorized items, the attempt may be cancelled and could risk further action. - Does the scan video get checked in real time?
Typically, you’ll receive instant confirmation if your scan is accepted. In rare cases, a manual review may add slight delay before you can proceed.
What This Means for Your DET Preparation
We know many students put intense time and effort into DET prep, working toward life-changing opportunities abroad. The last thing you want is to have your official test blocked at the setup stage! Here’s what you need to do before test day:
- Practice scanning your room: Don’t wait until the actual test. Use your own phone and simulate the exact motions and angles required by the DET room scan.
- Get familiar with the room scan checklist: Make a habit of decluttering, checking under your desk, and removing extras so you’re never caught off guard during setup.
- Read all DET official instructions: These may get updated and specific details may vary; always check directly for the latest guidance.
- Allocate extra time: Expect to spend an additional 5-10 minutes on setup. Rushing can result in errors or delays.
Technical Requirements and Troubleshooting
- Modern smartphone required: Most Android or iPhones from 2018 or later should work. If your phone is too old or the camera is blurry, arrange for another device ahead of time.
- Stable Wi-Fi preferred: Good connectivity is critical-you’ll need to upload video immediately.
- If you get stuck: Contact DET support via the official test platform or your test dashboard. Do not close your session until you receive instructions!
