Universities worldwide require international students to demonstrate English proficiency for admission. While IELTS and TOEFL have long been the standard, the Duolingo English Test has emerged as a highly accessible, flexible, and affordable alternative accepted by thousands of global institutions.
Unlike traditional testing centers, the Duolingo English Test is fully digital. It allows you to take the exam from the comfort of your home, with official results delivered in as little as 48 hours.
Because this is a remote, proctored assessment, strict security protocols govern your testing environment. Ensuring your device, internet connection, and physical space meet the required standards is essential for a successful certification.
Properly preparing your workstation in advance prevents technical disruptions and safeguards your exam’s validity.
Follow this comprehensive guide to ensure your Duolingo English Test setup meets every requirement.
Duolingo English Test setup requirements and technical checklist
Before launching the exam, meticulously prepare your testing environment and hardware. Double-check all of the following requirements:
- A valid government-issued photo ID (usually a passport)
- A computer (Mac or Windows) with a front-facing camera, microphone and speakers
- A smartphone with a working camera
- A reliable internet connection
- A quiet room with no other people around
- Good lighting with your face clearly visible.
- Use natural light if possible, or place a lamp in front of you. Avoid strong backlighting or sitting in front of a window, as this can make your face harder to see on camera.
- A simple background (a blank wall works best)
- The Duolingo English Test desktop app installed on your computer (you cannot take the test in a browser)
Run the official system check integrated into the Duolingo English Test platform. This utility evaluates your internet speed, microphone, speakers, webcam, and secondary camera connectivity. Conducting this check at least 48 hours before your exam helps you resolve potential hardware conflicts early.
A reliable setup creates a seamless testing experience; carefully audit your environment before you begin.
Duolingo English Test (DET) security protocols mandate a room scan, an ear scan, and the use of a secondary camera to maintain testing integrity.
Let's review these requirements to ensure you are fully prepared for the verification process.
How to set up the secondary camera for the Duolingo English Test
You will be required to configure a secondary camera—typically a smartphone—to provide a comprehensive view of your testing area.
This multi-camera system ensures that your remote environment remains secure, fair, and compliant with testing regulations.
1. Primary camera
Your primary computer webcam monitors your direct engagement with the test. It is used to record:
- Your face and upper body
- Your eye movements
- Your behaviour during the test
Your face, hands, and keyboard must remain in full view throughout the assessment to verify you are working without assistance.
2. Secondary camera
The secondary camera (usually a smartphone) provides a wider perspective of your room. It must clearly capture:
- Your computer screen
- The keyboard
- The desk
- The surrounding environment
These extra angles allow proctors to confirm that you are not using unauthorized devices or external materials. While tablets are permitted as secondary cameras, second laptops are prohibited.
Maintaining a stable camera mount is vital for preventing session interruptions.
If your secondary device disconnects or shifts, your test may be invalidated. Ensure your phone is fully charged and securely positioned on a stable mount, such as a sturdy stand or improvised stack of books.
To sync your smartphone, scan the provided QR code from your computer and follow the prompts in the Duolingo English Test app. Your phone must remain on a stable surface—never hold it—and be connected to Wi-Fi with sufficient battery.
How the Duolingo English Test room and ear scan work
Before beginning the exam, you will be guided through a 360-degree room scan to verify your testing environment is secure.
During this scan, ensure you clearly show:
- Hold your phone and slowly rotate around the room (in some cases you may use the laptop camera)
- Show your desk and the entire surface
- Show the walls and the area around your computer
- Make sure the keyboard and screen remain visible
The interface is highly intuitive and designed to guide you through each step.
Log in via the secure Duolingo English Test app. This step verifies your surroundings, ensuring no unauthorized notes, devices, or individuals are present.
The ear scan is a quick, standard verification step.
Simply present your ears clearly to the camera to prove you are not wearing prohibited headphones or earbuds.
This process is straightforward and takes only a few seconds.
Set up a clean and compliant workspace
Maintain a clean workspace; only allow the following items during your test:
- Your computer
- Your smartphone (as the secondary camera)
- Your ID
Remove all notebooks, loose papers, electronics, and headphones. A clear, clutter-free desk minimizes the risk of your test being flagged and ensures a smooth verification.
How long does the Duolingo English Test take?
The Duolingo English Test typically takes about one hour to complete, encompassing ID verification, the scored assessment, and the writing and speaking samples.
No appointments are necessary, and results are ready within two days.
Even with the correct equipment, violating testing protocols can result in an invalid score. Avoid these common mistakes:
- Looking away from the screen (except when typing)
- Speaking or reading aloud outside of the designated speaking tasks
- Leaving the camera view
- Taking notes or recording questions
- Interacting with another person
- Using headphones or earbuds (your ears must remain visible)
Disable all desktop and mobile notifications, and terminate any unnecessary background applications before you start. Enable "Do Not Disturb" mode on your phone; even a simple notification could lead to your test being flagged.
