Frequently asked questions
About Duolingo English Test preparation
What is the Duolingo English Test?
The Duolingo English Test (DET) is a fast, affordable, computer-adaptive English proficiency exam taken online from home. It tests Reading, Writing, Listening and Speaking in about an hour and is accepted by 5,000+ universities worldwide.
How does the Duolingo English Test work?
The DET is computer-adaptive — your answer is evaluated, the difficulty adjusts, and you move to the next task. This repeats throughout the adaptive section until your overall proficiency is estimated, rather than every candidate getting the same fixed set of questions.
How is the Duolingo English Test scored?
Current DET scores are reported from 10–160 in 5-point increments. Your Overall Score combines Individual subscores (Reading, Writing, Listening, Speaking) and Integrated subscores (Literacy, Comprehension, Conversation, Production).
What is a good Duolingo score?
120+ is competitive at most universities; 130+ opens up top-50 programs; 140+ is Yale / Columbia territory. Scores are reported on the 10–160 scale.
How long does the Duolingo English Test take?
The full test takes about one hour, including the adaptive test, a Writing Sample, a Speaking Sample and a Video Interview.
Can I take the Duolingo English Test from home?
Yes — the DET is fully online and taken at home, as long as you have a working camera, microphone, stable internet connection and a quiet, private room. The current security setup includes a secondary camera, room scan and ear scan.
How should I prepare for the Duolingo English Test?
Build familiarity with all DET question types, drill your weakest skills, get feedback on Speaking and Writing samples, and take full-length adaptive mock tests before test day. Official DET guidance emphasizes building real test readiness, not memorizing answers.
Is Duolingo accepted by universities?
It's accepted by 5,000+ institutions globally, including Ivies and Russell Group universities. Always confirm with your specific program — a small minority still require IELTS/TOEFL only.
What is the difference between Duolingo and IELTS?
DET is shorter (~1 hour vs ~2h 45m for IELTS), fully online and computer-adaptive, and significantly cheaper. IELTS is examiner-scored on a 0–9 band scale and can be taken on paper or computer at a test centre.
What is the difference between Duolingo and TOEFL?
DET is taken entirely at home in about an hour, while TOEFL iBT is longer and can be taken at a test centre or at home. DET is also considerably cheaper and returns results faster.
