What Is the Duolingo English Test? Complete 2026 Guide

What is the Duolingo English Test?

The Duolingo English Test (DET) is an online English proficiency exam you take from home on your own computer. No test centre, no travel, no waiting for weeks. It costs $70 and takes about one hour. Results arrive within 48 hours, or 12 hours with expedited delivery.

The test is accepted by over 5,700 universities and institutions worldwide and the number keeps growing. It is computer-adaptive, meaning questions adjust to your skill level in real time to measure your ability more precisely.

If your target school is on the list, you can skip the expensive, hours-long alternatives.

Who is the DET for?

The DET is for anyone who needs a certified English score but does not have the time or budget for traditional exams.

Are you an international student applying to a university abroad? A professional who needs proof of English for a job or registration? A high school student planning to study in another country? Is your application deadline a few weeks away?

The DET is worth considering if any of that fits. You do not need to visit a test centre. You do not need to book weeks in advance. You can take the test from a quiet room at home.

The DET reaches students in places where traditional test centres are scarce. Many of our students come from India, Pakistan, Saudi Arabia, Egypt, Vietnam, and across Africa and Europe. If your country has limited access to test centres, the DET removes that barrier.

One thing to watch: the DET is not accepted everywhere. If your target university does not accept DET scores, you will need a different exam. Confirm before you commit.

How does the DET work? Exam structure explained

The test has three parts.

The first part is the 5-minute setup. You verify your identity with a valid ID, show your room to the proctor via webcam, and test your microphone and camera. Miss the setup checks and your test may not be certified.

The second part is the 45-minute adaptive section. This is where your score is determined. The computer presents questions that adjust to your skill level. The diagram below shows the full exam flow and question types at a glance.

The third part is the 10-minute video interview. You respond to open-ended prompts on camera. Universities often watch this video to assess your real-world communication skills.

What is the DET scoring scale and how does it work?

The DET scores on a scale of 10 to 160 in 5-point increments. You receive an overall score plus four subscores: Literacy, Comprehension, Conversation, and Production. Each subscore tells universities something specific about your language ability.

The score bands align with the CEFR framework from basic through native-level fluency. Most undergraduate programs ask for 105 to 120. Graduate programs often ask for 120 or higher. Check your target university's specific requirements before you book.

How much does the DET cost?

The standard Duolingo English Test costs $70. No hidden fees, no extra charges for sending scores to universities. You pay once and your score is sent to as many schools as you like for free.

Third-party platforms offer discount voucher codes. Arno (arno.digital) and Mr. Luke's website both provide vouchers that reduce the test fee. Some vouchers bundle faster results at no extra cost. Check these before you pay full price.

Retaking the test is not a financial disaster.

Which universities accept the DET?

Notable universities that accept the DET, by country:

United States: Yale, Columbia, NYU, University of Michigan, University of California system, University of Texas, Boston University, Northeastern University.

United Kingdom: Imperial College London, University of Birmingham, University of Southampton, University of Bristol, University of Glasgow.

University acceptance policies change. A school that accepts the DET today may update its policy next year. Confirm with your target university's admissions office before you book.

How many times can you retake the DET? Retake policy explained

You can retake the DET as many times as you want. Each retake costs $70 (or less with discount vouchers).

Your previous results remain valid and can still be sent to universities. Only the scores you choose to share are visible to institutions. DET scores are valid for two years from the test date.

Where can you practice for the DET?

The DET question types are unique and the adaptive format means you cannot rely on memorised answers. You need to get comfortable with the interface and the timing.
