The Duolingo English Test (DET) has introduced a new ear-scanning requirement starting December 2025. This update is part of Duolingo English Test’s ongoing efforts. They aim to ensure fairness, security, and credibility in their widely recognized online English proficiency exam. At AAEC Global, we know how important the DET is for students applying to universities abroad, so here’s everything you need to know about this new rule.

Why DET Ear Scanning?

The primary purpose of Duolingo English Test Ear Scanning is to verify that test takers are not using wireless earbuds or hidden audio devices during the exam. By requiring students to scan both ears with their smartphone camera, DET’s proctoring system can detect unauthorized devices and maintain exam integrity.

How the Ear Scanning Works

The process, Duolingo English Test Ear Scanning, is straightforward and guided step by step within the DET desktop application:

Step 1: Launch the DET desktop app and sign in

Step 2: Enter the ear-scanning stage when prompted.

Step 3: Use your smartphone camera to scan one ear, keeping it centered in the frame.

Step 4: Hold the phone close to your ear for close-range verification.

Step 5: Repeat the process for the other ear.

This adds only a few minutes to the exam setup, but it’s crucial for compliance.

Implementation Timeline

• The ear-scanning feature, part of the Duolingo English Test Ear-Scanning process, is being rolled out gradually.
• If you don’t see the requirement yet, it means it hasn’t been activated for your test session.
• Eventually, all DET candidates will need to complete this step.

Tips for a Smooth Duolingo English Test Experience

To avoid last-minute stress, students should:

• Test your phone camera in advance to ensure it’s working properly.
• Choose a well-lit environment for clear recognition.
• Keep your phone steady during scanning.
• Follow instructions carefully on the DET app.
• Plan extra time for the new verification steps.
