The Duolingo English Test is a game-changer for students who want to prove their English level quickly, affordably, and from the comfort of home. 

But before you sit down to take the test, it’s important to understand the rules and guidelines of the Duolingo English Test.

In this guide, we’ll cover everything you need to know about the Duolingo English Test rules, from setup requirements to prohibited items and what happens if a rule is broken.

Let’s make sure you’re fully prepared!


Why Are Duolingo English Test Rules Important?

Ensuring Fairness and Accuracy

The Duolingo English Test uses an AI-driven adaptive testing system to test your English skills. 

In other words, most of your test is (mostly) marked by a computer. 

That means that the organisers of the DET have to be very strict with the rules. That’s because: 

  • These rules stop students from cheating – that means that your score accurately reflects your English level.
  • The companies, governments and universities who accept DET have to have faith that the results are reliable – and if students are cheating, they’ll stop accepting DET. 

Common Violations That Can Invalidate Your Duolingo English Test

Breaking the Duolingo English Test rules —intentionally or not—can result in your test being invalidated. 

In other words, you fail that test, even if your English is really good and you’ve prepared really well (for example, by taking our Duolingo English Test Complete Preparation Course).

So we definitely want to avoid this! Let’s find out what mistakes to avoid. 

Some common “violations” of the Duolingo English Test rules include:

  • Having another person in the room during the test.
  • Using a second monitor or electronic device.
  • Failing to maintain eye contact with the screen.

Key Duolingo English Test Rules

Identification and Room Setup Requirements

Before you start the test, make sure you have the following things:

  1. Valid ID: You’ll need a government-issued photo ID, such as a passport or driver’s license. Double check on the DET website to see if your ID will be accepted. 
  2. Room Setup: The room should be well-lit, quiet, and free of distractions. Ensure no other people are present. I recommend putting a sign on the outside of your room, saying “Keep Out, Mum! I’m Scoring 120 on my DET!”
  3. Plain Background: Your testing area should be free of notes, books, or other items. Don’t give the DET any chance to think you might be cheating. 

Prohibited Items During the Test

You definitely, definitely, definitely (definitely!!) shouldn’t have any of these with you when you take the DET:

  • Mobile phones, smartwatches, or other electronic devices.
  • Headphones or earbuds.
  • Notes, textbooks, or any external resources.

Behavior Guidelines While Taking the Test

As we know now, the DET is pretty strict! 

They even check the way that you are behaving in the test, to make sure you aren’t breaking any Duolingo English Test rules.

The test watches your behavior closely through your webcam. 

Keep these tips in mind:

  • Maintain Eye Contact: Always look at your screen—frequent glances away may trigger suspicion. I suggest practicing typing without looking at your fingers. 
  • Stay in Frame: Your face and shoulders should remain visible at all times.
  • Avoid Talking: Refrain from speaking aloud unless prompted. So, no saying to yourself, “Come on, you can do it!” – you’ll have to say it to yourself in your head! 

Technical Requirements to avoid breaking the Duolingo English Test rules

What Equipment Do You Need?

One of the big advantages of the Duolingo English Test is that you don’t have to go to a testing centre, like you do with IELTS. 

But… one of the big disadvantages is that you are responsible for setting up your exam area. 

This is probably the most important preparation that you’ll do before the DET.

Why? 

Because even if your English is perfect, if your internet connection drops out halfway through the exam, you’ll still fail! 

Here’s a checklist to ensure you’re technically ready:

  • Computer: A desktop or laptop with a camera, microphone, and speakers (make sure these are nice and loud, otherwise the Listening questions will be VERY difficult!)
  • Browser: The latest version of Chrome, Firefox, or Safari.
  • Stable Internet: A strong and consistent connection is essential to avoid interruptions.

Internet Speed and Browser Recommendations

Duolingo recommends an internet speed of 2 Mbps or higher for a good testing experience.

Remember though, 2Mbps is the minimum recommended – I would recommend finding a place with at least 10Mpbs if you can. 

And of course, always test your connection before the test to avoid unexpected problems.

In other words, do everything you can do to make sure your internet is ready. 


What Happens If You Break the Duolingo English Test Rules?

Test Invalidation and Consequences

Here’s the scary part. I’ve had so many students come to me after taking the test, saying things like; 

  • “My mum walked in during the test, and I failed!”
  • “I was looking away from the screen as I was thinking about what to write, and I failed!”
  • “Aliens came down to earth, came into my room, and started talking to me… and I failed!”

Well, that last one wasn’t exactly true… but the others are very common situations! 

So, what can happen if you break a rule in the DET? 

Well, the DET’s AI system is watching you carefully. 

If the AI thinks you are cheating in some way, your test may be flagged for review. 

That means a human will check the recording and judge if you were cheating. 

Common outcomes include:

  • Score Invalidation: Your results are void (i.e. they are cancelled), and you’ll need to retake the test.
  • No Refund: Duolingo does not issue refunds for invalidated tests.

And remember, the DET have to protect their reputation, so they are VERY strict with the rules. It’s a big danger. 


How to Appeal a Test Invalidation Decision

Most of the time, if your test is invalidated (i.e. cancelled), DET won’t change their minds. 

But if you really believe your test was unfairly invalidated, here’s what you can do:

  1. Contact Duolingo’s support team to explain the situation (don’t mention the aliens though!).
  2. Provide any relevant evidence, such as screenshots or internet speed tests.

Frequently Asked Questions About Duolingo English Test Rules

Can I Take the Test in a Shared Space?

No. The test requires a private room to prevent distractions and make sure you aren’t cheating. 

So if your home doesn’t have good internet and you need to find a place with a strong internet connection, choose carefully.

You can’t just go to a coffee shop. You need a private room. 

What Should I Do If I Lose Internet Connection During the Test?

If your internet drops, the test will pause. Reconnect as quickly as possible to resume where you left off. 

And if that happens, make sure you don’t lose your head.

Don’t start shouting, or step away from the screen, or start texting your friend to tell them what’s happened!

Because if the test reconnects suddenly, you’ll be caught breaking the rules. 

Instead, sit patiently and wait for the internet to reconnect.

That way, you have the best chance of continuing your DET and not losing your progress. 

Are There Exceptions to Certain Rules for Special Circumstances?

Yes. If you have specific needs, such as accessibility accommodations, contact Duolingo in advance to request adjustments.
