The Duolingo English Test (DET) has become one of the fastest-growing ways for international students to prove their English proficiency, largely because it removes two of the biggest headaches of traditional exams: you take it at home on your own computer, and you usually get your result within about two days rather than one to two weeks. It is fully online, computer-adaptive, and takes roughly an hour, which makes it dramatically more convenient than booking a test-centre slot for IELTS or TOEFL. That convenience is real, but it comes with one crucial caveat that this guide keeps returning to: acceptance is growing quickly but is not universal, so the single most important thing you can do before spending money on any test is confirm that every university and programme on your shortlist actually accepts the DET, and at what minimum score.
This guide explains what the test is, who needs it, how the format and scoring work, and — most usefully — how to prepare for a test that rewards genuine English ability rather than memorised tricks. Treat every fee and score figure here as a planning range and confirm the current details on the official site at englishtest.duolingo.com before you commit.
Key Takeaways
- The Duolingo English Test is an at-home, online, computer-adaptive English exam that takes about one hour and is scored on a 10–160 scale in 5-point increments; the fee is around US$70 at the time of writing (confirm the current fee on the official site).
- It is used mainly for university admission and, in some countries, as supporting evidence for study visas — but acceptance is growing rather than universal, so confirm each programme accepts the DET and check its minimum score before booking.
- Typical university requirements fall broadly in the 105–120+ range for competitive programmes, with many undergraduate courses accepting 95–115; the only reliable number is the one on your programme's own page.
- Because the test measures your real English level, the best preparation is weeks of daily English practice plus the free official practice test, not last-minute cramming.
- Results are usually certified and available within about two days, and you can send them to institutions for free from your results dashboard.
What the Duolingo English Test Is and Who Needs It
The Duolingo English Test is an online English-proficiency assessment designed to measure academic English across four core skills — reading, writing, listening, and speaking — using a single adaptive test rather than separate timed papers. "Adaptive" means the difficulty of each question adjusts to your performance: answer well and the questions get harder; struggle and they get easier. This lets the test estimate your level efficiently in far less time than a fixed-length exam, which is why the whole thing fits into roughly an hour.
Most people who take the DET do so for university and college admission, and it is accepted by thousands of institutions worldwide — Duolingo reports acceptance by well over six thousand programmes across many countries. That number is climbing every year, but it is still not the case that every university, or every programme within a university that accepts it generally, treats the DET as equivalent to IELTS or TOEFL. Some universities accept it only for certain courses, or set a higher bar for it, or use it as a first-stage screen. In a handful of countries the DET is also accepted as part of a study-visa English-evidence requirement, but immigration rules are separate from admissions rules and change often, so never assume a test that satisfies your university will automatically satisfy a visa authority.
The practical takeaway is the same one every honest guide should lead with: the DET is convenient and affordable, but its usefulness to you depends entirely on whether your target universities accept it. Build your university shortlist first — you can compare options through TheUniFinder's programmes and universities catalogues — then check each institution's English-requirements page, and only then decide whether the DET, IELTS, or TOEFL is the right test to sit. If you are still weighing the options, our comparison of IELTS vs TOEFL vs PTE walks through how the mainstream tests differ, and our dedicated IELTS preparation guide and TOEFL preparation guide cover the two most widely accepted alternatives in depth. Country application guides such as how to apply to universities in Australia explain where English evidence fits into the wider admissions process, and if funding is part of your plan, TheUniFinder's scholarship finder helps you find awards that match your profile.
Duolingo English Test Format
The test is delivered entirely on your own computer, in a single uninterrupted sitting, and is broken into three broad parts. Note that individual question timings and the exact mix of question types are set by the test itself and can vary, so the table below describes the structure rather than a fixed script.
| Part | What it involves | Delivery | Rough duration |
|---|---|---|---|
| Onboarding and setup | ID check, rules, equipment and room checks | At-home, on your computer | ~5 minutes (not scored) |
| Adaptive graded section | A mix of reading, writing, listening, and speaking question types that adapt in difficulty | Computer-adaptive | ~45 minutes (scored) |
| Speaking and writing sample | An open-ended video/writing sample sent to institutions alongside your score | At-home, recorded | ~10 minutes (sample, not part of the numeric score) |
Question types in the adaptive section commonly include reading and completing words in text, listening and transcribing spoken sentences, reading a passage aloud, describing an image or photo in speech and in writing, listening to and answering questions about audio, and writing or speaking in response to a prompt. Because the test is adaptive, no two test-takers see exactly the same sequence, and you cannot go back and change earlier answers. The whole experience — setup, graded section, and the speaking/writing sample — typically totals about an hour.
Two features make the DET feel different from a traditional exam. First, it is proctored remotely: your session is recorded and reviewed, and the rules about your environment (a quiet, private, well-lit room; no notes; no other people; eyes on the screen) are strict, because a violation can invalidate your result. Second, the speaking and writing sample is not scored numerically but is shared with the universities you send your results to, so admissions staff can see and hear a real sample of your English. That makes it worth taking seriously even though it does not directly move your number.
Scoring and What Score You Need
The Duolingo English Test is reported on a scale of 10 to 160, in 5-point increments (so 105, 110, 115, and so on). Alongside the overall score, certified tests provide subscores in four areas — Literacy, Comprehension, Conversation, and Production — which are built from your underlying skills in reading, writing, listening, and speaking. These subscores help universities see whether your strengths and weaknesses are balanced, which matters for programmes that care particularly about, say, speaking or writing.
Duolingo publishes official concordance tables mapping DET scores to the CEFR levels and to IELTS and TOEFL scores, and as a very rough orientation:
- A DET score in the 95–105 range corresponds broadly to the lower end of what many undergraduate programmes accept.
- A DET score around 110–120 corresponds broadly to a mid-to-strong IELTS band (roughly 6.5–7.0), which many competitive undergraduate and taught-postgraduate programmes look for.
- Scores of 125 and above correspond to a high level of proficiency suitable for the most selective programmes.
Those bands are only a compass, not a requirement. Each university sets its own minimum overall score and, sometimes, minimum subscores, and these vary widely by country, institution, and course. A safe planning assumption is that typical requirements fall in the 105–120+ range for competitive courses, with some undergraduate programmes accepting 95–115 — but the only number that matters is the one published on your specific programme's admissions page. Always confirm both the minimum overall score and any subscore minimums directly with each university before you book, and check whether they require the test to have been taken within a certain recency window.
How to Prepare for the Duolingo English Test
Preparing for the DET is genuinely different from preparing for a traditional exam. Because the test measures your current, real English ability, cramming the night before will not meaningfully change your score — but a few weeks of focused, daily practice absolutely can. The following steps mirror the workflow the official guidance recommends.
Register and choose a test date
Create an account on the official Duolingo English Test site and read the technical and environment requirements before you pay: you need a reliable computer with a working webcam and microphone, a stable internet connection, a valid government photo ID, and a quiet, private room. Only buy a test once you are within a few weeks of being ready, since purchased tests have a window in which they must be completed. Booking is on-demand rather than tied to fixed test dates, which is one of the DET's biggest conveniences.
Take a diagnostic test
Sit the free official practice test early. It uses the same adaptive format as the real exam and gives you an estimated score range, so it doubles as a diagnostic: it shows you where you currently stand relative to your target universities' minimums, and it reveals which skills — reading, listening, speaking, or writing — are dragging your result down. You can take the free practice test more than once, which makes it the single most valuable preparation tool available.
Build a study plan
Use the gap between your diagnostic score and your target to plan several weeks of daily English immersion rather than isolated study sessions. Effective daily practice includes reading articles and academic texts in English, listening to podcasts or lectures, speaking aloud (describing images, summarising what you read, answering prompts), and writing short timed responses. Weight your effort toward your weakest subscore area. Because the DET rewards overall fluency, this "little and often" approach beats occasional marathon sessions.
Practise with official materials
Beyond the free practice test, use the official Test Readiness resources and sample-question walkthroughs so that every question type — reading passages aloud, transcribing audio, completing text, describing an image in speech and writing — feels routine. Familiarity with the format removes the anxiety of being surprised on test day and lets you spend your mental energy on the English itself rather than on figuring out what a question is asking.
Sit full timed mock tests
In the final week or two, complete at least one or two full practice runs under real conditions: same time of day if possible, quiet room, webcam on, no interruptions. This builds the stamina to stay focused for an hour and, crucially, lets you rehearse the speaking and writing sample, which many test-takers neglect because it does not directly affect the number. Practising speaking spontaneously in response to a prompt — and writing a clear, well-organised short response quickly — pays off in the impression your sample makes on admissions readers.
Test day and sending scores
On test day, set up your room to meet every rule: quiet, private, well-lit, no notes, no one else present, and your ID ready. Complete the test in one uninterrupted sitting — you cannot pause it. After you submit, your test is reviewed and certified, usually within about two days, after which you can send your result to universities for free directly from your results dashboard. Send scores to every institution on your shortlist that accepts the DET; there is generally no per-institution sending fee, which is another cost advantage over some traditional tests.
Cost and Registration
At the time of writing, the Duolingo English Test costs around US$70, paid online when you buy the test. That is substantially cheaper than most IELTS or TOEFL registrations, and there is typically no separate fee to send your certified results to institutions — a meaningful saving if you are applying to several universities. Fees can change and may be shown in your local currency, and fee waivers or access programmes exist for eligible low-income applicants through some institutions, so always confirm the current fee on the official site before budgeting.
Registration is on-demand: you buy a test, then complete it within its allowed window, at a time and place of your choosing, as long as your equipment and room meet the requirements. There are no fixed test-centre dates to work around, which is why the DET is often the fastest route to a usable English score when deadlines are tight. If a test is invalidated for a rule violation, though, you generally have to pay again — so read the rules carefully rather than risking a re-sit.
Common Mistakes to Avoid
- Assuming every university accepts it. This is the big one. Acceptance is growing but not universal, and some institutions that accept the DET set a higher score bar or restrict it to certain programmes. Confirm acceptance and the minimum score for each target programme before you pay.
- Cramming instead of building ability. The test measures real English, so a single night of study barely moves your score. Weeks of daily reading, listening, speaking, and writing do.
- Ignoring the speaking and writing sample. It does not change your number, but universities see and hear it. A weak, unprepared sample can undercut a good score.
- Breaking the environment rules. Looking off-screen, having notes visible, or letting someone enter the room can invalidate your result and cost you the fee. Rehearse a compliant setup in your mock tests.
- Leaving no buffer before deadlines. Results usually arrive within about two days, but reviews can occasionally take longer, and you may want time to re-sit for a higher score. Test well before your earliest application deadline.
- Overlooking subscore minimums. Some programmes require minimum subscores as well as an overall score; check both, and target your practice at your weakest area.
Frequently Asked Questions
Is the Duolingo English Test accepted by all universities?
No. The DET is accepted by thousands of institutions worldwide and that number keeps growing, but acceptance is not universal. Some universities accept it only for certain programmes, set a higher minimum score for it than for IELTS or TOEFL, or do not accept it at all. Always confirm on each university's own English-requirements page that it accepts the DET, and at what minimum overall and subscore, before you book the test.
How is the Duolingo English Test scored?
The test is scored on a scale of 10 to 160 in 5-point increments, based on your performance across adaptive reading, writing, listening, and speaking question types. Certified results also include four subscores — Literacy, Comprehension, Conversation, and Production. Duolingo publishes concordance tables linking DET scores to CEFR levels and to IELTS and TOEFL ranges, but each university sets its own required minimum, so check your target programme's page for the exact number.
How much does the Duolingo English Test cost?
At the time of writing the fee is around US$70, paid online when you purchase the test, and there is usually no additional charge to send your certified result to institutions. Fees can change and may appear in your local currency, and some applicants may qualify for fee waivers through institutional access programmes. Confirm the current fee on the official site at englishtest.duolingo.com before budgeting.
How long does it take to get Duolingo English Test results?
Results are typically reviewed, certified, and made available within about two days of completing the test, after which you can send them to universities for free from your results dashboard. Occasionally a review takes longer, so it is wise to take the test well before your earliest application deadline rather than relying on the fastest possible turnaround.
How should I prepare for the Duolingo English Test?
Because the test measures your real English ability, the most effective preparation is several weeks of daily English practice — reading, listening, speaking aloud, and short timed writing — combined with the free official practice test, which shows you the adaptive format and estimates your score. Rehearse the speaking and writing sample, complete at least one full timed mock in a compliant room, and target your practice at your weakest subscore area rather than cramming the night before.
