As remote testing becomes more widely accepted, ensuring the security and integrity of these tests is more important than ever. At Duolingo, we’re committed to making sure that every test taker has a fair and reliable experience, which is why we’ve introduced a new two-camera system to enhance the security of the DET!
This new feature combines the computer’s webcam and a secondary camera—usually a smartphone—giving our proctors a comprehensive view of the test taker’s environment. So, what does this mean for students, and how will it help ensure fairness and transparency? Let’s take a closer look.
How does the two-camera system work?
The two-camera system works by using the primary camera (the computer’s webcam) and a secondary camera (a smartphone or tablet) to capture a more complete picture of the test-taking environment.
Primary Camera (Computer Webcam):
- Focuses on the test taker’s face and upper body.
- Monitors eye movements and general behavior to detect any unusual activities.
Secondary Camera (Smartphone or Tablet):
- Captures a wider view of the test environment, including the computer screen and keyboard.
- Provides additional angles to ensure there are no unauthorized materials or devices.
Why do two cameras matter for test takers?
For test takers, the two-camera system provides more than just a security upgrade—it helps to ensure that their scores are trusted by institutions. By offering a comprehensive view of the test-taking environment, the two-camera system creates an additional layer of protection against cheating, while also reassuring honest test takers that their efforts will be recognized.
This approach benefits both students and institutions by increasing the confidence that test scores accurately reflect a student’s abilities.
What will test takers need to use the two-camera system?
Test takers will need a few basic items to take advantage of the new two-camera system:
- A laptop or computer with a webcam (primary camera).
- A smartphone or tablet with a camera (secondary camera).
- A reliable internet connection.
- A well-lit, quiet room for testing.
- A stable object (like a mug or phone stand) to prop up the phone.
- A government-issued photo ID.
It’s important to note that test takers can borrow a phone if they don’t own one, and while a tablet can be used, a second laptop cannot.
More frequently asked questions
How can test takers ensure their phone is properly positioned?
The phone’s video feed will be visible on the computer screen during setup. Adjust the phone until the screen and keyboard are fully visible in the frame. A sturdy object like a book or mug can help prop up the phone.
Do test takers need special equipment?
No special equipment is needed. Test takers can use common household items to keep the phone stable during the test. A phone stand or leaning the phone against an object works perfectly.
What happens if the secondary camera video is interrupted?
If the video from the secondary camera is interrupted, obscured, or tampered with, the test session will be canceled or invalidated, and test takers will need to retake the test.
What if the phone falls over during the test?
Since the test is timed, it’s recommended that test takers restart the test if their phone falls over during the session. They should make sure their setup is stable before starting, to avoid interruptions.
Can the secondary camera replace the computer’s camera?
No, both the computer’s webcam and the secondary camera are required to complete the test. The two cameras work together to provide a complete view of the test environment.
Ensuring fairness and confidence for all test takers
At Duolingo, we’re always looking for ways to make the test-taking experience as fair, secure, and accessible as possible. The new two-camera system is a step forward in ensuring that the Duolingo English Test continues to offer the highest level of integrity. By giving institutions more confidence in the security of test sessions, we’re also helping students demonstrate their English proficiency with complete peace of mind.
The new two-camera system isn’t just about preventing misconduct—it’s about creating an environment where honest test takers can thrive, knowing their efforts will be recognized and respected.
