What is a good Duolingo English Test score?
There is no universal answer, because the test has no pass mark — each institution sets its own requirement. As a rough guide, many undergraduate programmes ask for 105–120 and many postgraduate programmes ask for 120–130, but you should check the specific requirement for the course you are applying to rather than aim at a general number.
In CEFR terms, 100–125 is B2 and 130–150 is C1.
What is the highest score on the Duolingo English Test?
160. Scores run from 10 to 160, in increments of 5, so the possible results are 10, 15, 20 and so on up to 160.
How is the Duolingo English Test scored?
It is computer-adaptive. Questions get harder when you answer well and easier when you do not, and the test keeps going until the scoring engine is confident about your level rather than until a fixed number of questions is finished. That is why two people can sit the same test and answer a different number of questions.
Your final score is the average of your four individual subscores, rounded to the nearest 5.
What subscores does the Duolingo English Test report?
Eight. Four individual subscores — Reading, Writing, Speaking and Listening — and four integrated subscores, each of which is the average of two individual ones:
- Literacy — Reading + Writing
- Comprehension — Reading + Listening
- Conversation — Listening + Speaking
- Production — Writing + Speaking
Because each skill feeds two integrated subscores, one weak skill pulls down two numbers at once.
How long is a Duolingo English Test score valid?
2 years from the test date. After that you can still see the result in your account, but you can no longer share it with institutions.
How long does the Duolingo English Test take?
about one hour, including the adaptive section and the writing and speaking samples. There is no scheduled break, so plan to sit down and finish in one go.
How much does the Duolingo English Test cost?
$70 USD for the official test at the time of writing. Check Duolingo's site for the current price — we do not sell the official test.
How many times can I take the Duolingo English Test?
You can purchase three tests in any 30-day period. There is no cap on the total number of times you can take it over a longer period, and there is no penalty for retaking beyond paying again.
How quickly do I get my results?
Usually within 2 days of finishing. Results are reviewed before they are certified, which is why they are not instant.
Is the Duolingo English Test proctored?
Yes, remotely. You are video and audio recorded for the whole session and human proctors review the recording before your result is certified. There is no live person watching you in real time, but the review is real and results can be withheld.
What can get my Duolingo English Test result rejected?
Looking away from the screen repeatedly, anyone else being audible or visible, leaving the frame, using a phone or notes, or your face being unclear. The most common cause is simply looking away too often — people glance around while thinking and it reads as searching for help.
Take the test somewhere quiet, alone, well lit, with nothing on the desk.
How does the Duolingo English Test compare to IELTS and TOEFL?
The DET is shorter (about one hour against roughly three hours), cheaper, taken at home rather than at a centre, and returns results in 2 days rather than up to two weeks. It is scored 10–160 rather than IELTS 0–9 or TOEFL 0–120.
Comparison tables between the three exist, but treat them as approximate: the tests measure overlapping but not identical things, and institutions set their own equivalences.
Do universities accept the Duolingo English Test?
Thousands do, across the US, UK, Canada, Australia and Europe — but acceptance is per-institution and sometimes per-programme. Confirm on the admissions page of the specific course before you book, not from a general list.
Are these mock tests the same as the real Duolingo English Test?
No, and we would not claim otherwise. They follow the same structure, the same 11 current question types, the same adaptive logic and the same 10–160 reporting scale, and they are written to the same difficulty range.
What they cannot do is reproduce Duolingo's calibrated question bank or their exact scoring model, both of which are proprietary. Treat your result here as a well-founded estimate of where you are, not as a prediction of your official score.
