How DET scoring works
The Duolingo English Test reports an overall score from 10 to 160, in 5-point increments (10, 15, 20, all the way to 160). You will never see a score like 117 or 123, only multiples of 5.
Your overall score is derived from your performance across four core skills: Reading, Writing, Listening, and Speaking. These are computed adaptively throughout the test. The test’s adaptive engine adjusts question difficulty in real time: answer well, and the next question gets harder; struggle, and it eases off. This means the test converges quickly on an accurate estimate of your ability rather than working through a fixed set of questions regardless of how you’re doing.
Because the DET is adaptive and integrates skills within single tasks (rather than testing them in fully separate sections like IELTS or TOEFL), your final score reflects overall communicative competence rather than four cleanly siloed skill scores. That said, Duolingo does still report skill-specific and integrated subscores, covered next.
The four subscores explained
Alongside your overall score, your DET report includes four integrated subscores, each also on the 10-160 scale:
Literacy – your ability to read and write English. This is often weighted heavily by academic programmes where most coursework is reading- and writing-based.
Comprehension – how well you understand spoken and written English. Especially relevant for lecture-heavy, discussion-driven degree programmes.
Conversation – your ability to listen and respond in a natural back-and-forth exchange. This matters for MBA programmes, law schools, seminars, and any teaching style built around discussion.
Production – your fluency in generating both spoken and written English on demand, reflecting how comfortably you’ll contribute in presentations and writing-intensive coursework.
Your report also includes individual subscores for Reading, Writing, Listening, and Speaking specifically, giving universities (and you) an even more granular view.
Why this matters beyond the headline number: a composite score of 110 with one subscore sitting well below the others can raise questions with admissions reviewers, even if the overall number clears the bar. Balanced performance across all four areas strengthens your application more than a lopsided score profile with one very high and one very low subscore. Some universities also publish minimum subscore requirements alongside their overall minimum, particularly for programmes with a heavy discussion or writing component, so check for this on your target university’s admissions page.
CEFR levels and what they mean
DET scores are aligned to the Common European Framework of Reference for Languages (CEFR), the international standard used to describe language ability from A1 (beginner) to C2 (mastery).
| DET score range | Approximate CEFR level | What it represents |
|---|---|---|
| 10-55 | A1-A2 | Basic user – simple phrases and familiar topics |
| 60-85 | B1 | Independent user – can handle everyday situations and familiar academic contexts |
| 90-115 | B2 | Independent user, upper level – comfortable with most academic and social English |
| 120-145 | C1 | Proficient user – fluent, flexible, and effective in academic and professional settings |
| 150-160 | C2 | Mastery – near-native command of English |
Most university admissions requirements sit in the B2-C1 range (roughly 100-130), which reflects the level needed to follow lectures, participate in seminars, and produce academic writing independently.
What counts as a “good” DET score?
There’s no single “good” score. It depends entirely on your target university, programme, and level of study. That said, general benchmarks help you calibrate expectations:
| Score range | General category | Typical context |
|---|---|---|
| Below 85 | Below most university minimums | Rarely sufficient for direct degree entry; foundation or pathway programmes may still accept it |
| 90-105 | Standard undergraduate range | Meets many undergraduate programme minimums |
| 105-120 | Competitive range | Meets requirements at most competitive programmes and many graduate programmes |
| 120-135 | Highly competitive range | Meets requirements at highly selective universities, including many top-50 institutions |
| 135-160 | Exceptional | Comfortably exceeds virtually every published requirement; reflects near-native fluency |
As a rule of thumb: undergraduate programmes typically ask for 90-110, while graduate programmes (master’s and PhD) often require 115 or above, reflecting the heavier reading, writing, and seminar-discussion demands of postgraduate study.
Score requirements by university tier
Exact requirements always vary by institution and programme, but here’s a general pattern to help you calibrate before you check specific schools.
| Institution tier | Typical DET minimum | Notes |
|---|---|---|
| Community colleges / pathway programmes | 75-95 | Often paired with an English foundation or bridge course |
| Standard undergraduate programmes | 95-110 | The most common range across mid-tier universities globally |
| Competitive undergraduate programmes | 110-120 | Includes many well-ranked public and private universities |
| Top-50 global universities | 120-135 | Includes several Ivy League and Russell Group institutions |
| Highly selective graduate programmes (MBA, law, top STEM) | 125-140 | Discussion-heavy programmes may also set minimum subscore thresholds |
Always verify the exact figure on your specific university and programme’s admissions page. Published minimums change, and requirements often differ meaningfully between undergraduate and graduate admissions at the same institution.
DET to IELTS and TOEFL conversion
Universities that have historically used IELTS or TOEFL sometimes publish DET requirements as a converted equivalent. These conversions are approximations, not official one-to-one mappings, since the tests measure proficiency slightly differently.
| DET score | Approximate IELTS band | Approximate TOEFL iBT score | Approximate PTE score | CEFR level |
|---|---|---|---|---|
| 85-95 | 5.5-6.0 | 60-78 | 42-57 | B1-B2 |
| 100-110 | 6.0-6.5 | 79-93 | 58-64 | B2 |
| 115-125 | 6.5-7.0 | 94-101 | 65-72 | B2-C1 |
| 130-140 | 7.0-7.5 | 102-109 | 73-78 | C1 |
| 145-160 | 7.5-8.5+ | 110-120 | 79-90 | C1-C2 |
If a university has only ever published an IELTS or TOEFL requirement and hasn’t yet listed a DET equivalent, this table gives you a reasonable estimate, but always email admissions to confirm before relying on it for a real application decision. For a full breakdown of how DET stacks up against the other major English tests beyond just scoring, see our DET vs IELTS vs TOEFL vs PTE comparison.
What’s a percentile rank and why it matters
Alongside your score, your DET report shows where you land relative to other test-takers, typically expressed as 25th and 75th percentile context around your score. This helps you (and admissions staff) understand not just your raw score but how it compares to the broader pool of test-takers.
A percentile rank doesn’t change your eligibility for a university’s stated minimum score. It’s contextual information, useful mainly for understanding your relative standing and for tracking improvement between attempts if you retake the test.
What universities actually see on your score report
When you send your DET results to a university, they receive more than a single number. The full report includes:
- Overall score (10-160)
- Four integrated subscores: Literacy, Comprehension, Conversation, Production
- Four individual skill subscores: Reading, Writing, Listening, Speaking
- CEFR level mapping (A1-C2)
- A short video interview sample (roughly 30-90 seconds of you speaking on a given prompt)
- Writing sample, showing an actual piece of your written English
- A certified, tamper-proof result with a unique verification link, so universities can confirm your score is genuine
- Test date and validity window
The video interview and writing sample matter more than students often assume. Where a live IELTS Speaking test gives an examiner a full impression of your spoken English, DET’s short video sample is the closest equivalent, and admissions staff do look at it, particularly at competitive institutions.
Score validity and retaking the test
DET scores are valid for 2 years from your test date. Plan around your intended intake carefully: a score from June 2024 expires in June 2026, so if you’re testing more than two years ahead of your planned start date, you may need to retake it regardless of how strong your original score was.
If your score falls short of a target requirement, you can retake DET relatively quickly. Duolingo allows up to a limited number of test purchases within a rolling 30-day period (check the current policy on the official DET site, as retake rules are occasionally adjusted). Because DET costs a fraction of IELTS or TOEFL, retaking it is a far smaller financial decision. At $60 through Comet, a second attempt is a modest expense rather than another $200+ commitment.
Before retaking, don’t rush. Take 1-2 weeks to target the specific subscore that held your composite score back, rather than immediately resitting the test with the same preparation gaps. Duolingo doesn’t publish an official average score gain between attempts, but targeted preparation between attempts consistently produces better results than an immediate, unprepared retake.
How to improve a specific weak subscore
Your subscore breakdown tells you exactly where to focus, rather than guessing at generic “improve your English” advice.
Low Literacy (reading and writing)? Read varied English texts daily, including academic articles, not just casual content. Practise writing full responses under timed conditions rather than only reading passively.
Low Comprehension (listening and reading)? Watch English-language content without subtitles and listen to podcasts or lectures at natural speaking speed. Comprehension weakness is often really a speed problem: you understand the words but not fast enough under test conditions.
Low Conversation (listening and speaking)? Practise real back-and-forth exchanges with another speaker, not just monologue practice. DET’s conversation tasks reward natural responsiveness, not memorised scripts.
Low Production (speaking and writing fluency)? Record yourself answering timed prompts and listen back critically for clarity, hesitation, and structure. DET’s production tasks are timed with no option to re-record, so fluency under pressure is the specific skill to build, not just vocabulary range.

Common scoring mistakes and misunderstandings
1. Assuming the overall score is all that matters. Universities see your full subscore breakdown. A lopsided profile, strong overall score but one very weak subscore, can raise flags even when the composite number clears the bar.
2. Converting from an IELTS or TOEFL requirement instead of checking for a published DET minimum.Conversion tables are estimates. If your university has published an official DET requirement, use that number directly.
3. Not accounting for the 2-year validity window against your actual intake date. A strong score taken too early can expire before you need it.
4. Retaking immediately without addressing the specific weak subscore. An unprepared, immediate retake rarely improves on the same weaknesses that caused the first low subscore.
5. Ignoring subscore minimums for discussion- or writing-heavy programmes. Some MBA, law, and journalism programmes set minimum thresholds on Conversation or Literacy specifically, not just the overall score. Check for this explicitly.
6. Assuming every university publishes a DET requirement. Some institutions have only published IELTS or TOEFL minimums so far. If DET isn’t listed, email admissions directly to confirm both acceptance and the expected score, rather than guessing from a conversion table.
Frequently asked questions
160 is the maximum. A score this high reflects near-native command of English and is far beyond what any university requires.
Most universities require somewhere between 90 and 120, depending on the programme and level of study. Undergraduate programmes typically ask for 90-110; graduate programmes often require 115 or above.
To most admissions committees, the overall score matters most. But faculty in specific departments, particularly writing-intensive or discussion-heavy programmes like journalism, law, or MBA courses, may look closely at your Literacy or Conversation subscores specifically. Aim for balanced subscores rather than one very high score offsetting a very low one.
Two years from your test date. Plan your test timing around your intended intake so your score doesn’t expire before you need it.
Yes. DET allows retakes within a limited window (check current Duolingo policy for exact rules), and because it costs a fraction of IELTS or TOEFL, retaking it is far less costly. Take time to target your specific weak subscore before resitting rather than retaking immediately.
Approximately, a DET score of 100-110 corresponds to roughly IELTS 6.0-6.5 or TOEFL 79-93. These conversions are estimates; always check whether your target university has published an official DET requirement before relying on a converted figure.
Yes, particularly at more selective institutions. The short video sample is the closest equivalent to a live speaking assessment and gives admissions staff a sense of your natural spoken English beyond the numerical score.
Generally 120-135, though this varies significantly by institution and programme. Always confirm the exact published minimum for your specific target school.
It depends on the programme. Many graduate programmes require 115 or above, so 100 may fall short for some, though pathway or foundation-year options sometimes exist. Check your specific programme’s minimum directly.
It can, particularly for programmes that weigh specific skills heavily, such as writing-intensive or seminar-based courses. Balanced performance across all four subscores strengthens your profile more than an uneven one.
