What is the Duolingo English Test?
The Duolingo English Test (DET) is an online, adaptive English proficiency test accepted by 6,500+ universities and institutions worldwide. You take it at home in about one hour, and it scores your reading, writing, listening and speaking on a single 10–160 scale.
- Online and at home — no test centre, about one hour, on your own computer
- Scored 10–160 with 8 subscores across all four skills
- Results in 2 days, valid 2 years, $70 USD per test
The Duolingo English Test is a computer-adaptive test of English proficiency, taken entirely online. It measures reading, writing, listening and speaking in about one hour, and reports a score from 10 to 160 that universities, employers and immigration authorities use to judge whether your English is strong enough to study or work in an English-speaking setting. It is made by Duolingo — the same company as the language-learning app — but it is a separate, proctored exam, not the app's lessons.
Because it is taken at home, costs $70 USD, and returns results in 2 days, it has become a mainstream alternative to IELTS and TOEFL: 6,500+ institutions now accept it. This page explains the format, the scoring, who accepts it, what it costs, and exactly how you take it.
What the test looks like
The Duolingo English Test takes about one hour from start to finish and runs in three parts:
| Part | Time | Purpose |
|---|---|---|
| Setup & ID check | 5 min | You verify your identity and the system checks your camera, microphone and room. |
| Adaptive graded section | 45 min | The scored core — 11 question types that adapt in difficulty to your answers. |
| Writing & speaking sample | 10 min | An open writing and speaking response, sent to institutions alongside your score. |
The 45-minute core is adaptive: each question is chosen from how you answered the last, so the test homes in on your level quickly instead of asking everyone the same fixed set. It draws from 11 question types that mix reading, writing, listening and speaking. See all 11 question types explained, or sit them under time in a full mock test.
How the 10–160 score works
Your result is a single number from 10 to 160, in increments of 5. It is not a percentage or a count of right answers — because the test is adaptive, the difficulty of what you were asked is built into the score, so two people who got the same number right can score differently. Alongside the overall score you get 8 subscores: four skills (Reading, Writing, Listening, Speaking) and four combined areas (Literacy, Comprehension, Conversation, Production). The overall score is the average of the four combined areas.
Scores map to the CEFR levels universities recognise:
| CEFR level | DET score |
|---|---|
| A1–A2 | 10–55 |
| B1 | 60–95 |
| B2 | 100–125 |
| C1 | 130–150 |
| C2 | 155–160 |
For the full mechanism — how each subscore is built and what the adaptive engine is doing question by question — see how the DET is scored. To place a DET score against IELTS and TOEFL, use the score converter or the score comparison.
Who accepts the Duolingo English Test
6,500+ universities and institutions accept the DET, including many of the best-known names in the US, UK, Canada, Australia and across Europe and Asia. Acceptance is concentrated in North America but now reaches every region:
| Region | Accepting institutions |
|---|---|
| North America | 4,300+ |
| Europe | 800+ |
| Asia | 600+ |
| Oceania | 200+ |
| South America | 100+ |
| Africa | 50+ |
What actually matters is whether your specific programme accepts it and the minimum score it asks for, so always check the university's own page. Our list of universities that accept the DET is the place to start, and study abroad without IELTS covers the routes country by country.
DET vs IELTS and TOEFL
The DET measures the same English as IELTS and TOEFL but differs in how you take it. It is cheaper ($70 USD against roughly $200–$310 for the others), taken at home rather than at a test centre, and returns results in 2 days instead of one to two weeks. The trade-off is that a few institutions still prefer IELTS or TOEFL, so acceptance — while wide — is not yet universal.
As a rough guide, DET 120–125 ≈ IELTS 6.5–7.0 ≈ TOEFL iBT 84–93. For the full picture see Duolingo English Test vs IELTS and the score comparison.
What it costs, and how results work
The test costs $70 USD per attempt, and you can take up to three tests in any 30-day period. Results arrive within 2 days and stay valid for 2 years from the test date — after that you would retake it. Sending your score to institutions is free and unlimited within the validity window.
