DET Scoring Explained

DET Score RangeCEFR LevelAdmissions Interpretation
10 – 55A1 – A2Basic user. Below typical admissions thresholds.
60 – 85B1Intermediate. May meet minimum requirements for pathway or foundation programmes.
90 – 115B2Upper-intermediate. Meets requirements for many undergraduate programmes.
120 – 135C1Advanced. Meets requirements for most graduate and competitive programmes.
140 – 160C2Very advanced. Exceeds requirements at virtually all programmes.

A Note on Score Conversions

You will find many websites offering generic DET-to-IELTS or DET-to-TOEFL conversion tables. Treat these with caution. Duolingo provides only broad CEFR alignments, and each university sets its own equivalency. A DET 120 may correspond to IELTS 7.0 at one institution and 6.5 at another. Always check your target programme's admissions page for the exact DET score they require rather than relying on third-party conversion charts.

Universities Accepting the DET

Over 6,500 programmes worldwide accept DET scores. Below is a sample of prominent institutions by destination.

Which Test Should You Choose?

Every test has its strengths. Use these decision points to find the best fit for your situation.

Choose DET if…

  • You want to test from home without travelling to a centre
  • You need results quickly (within 48 hours)
  • Budget is a concern — DET costs a fraction of IELTS or TOEFL
  • Your target universities accept DET scores
  • You prefer a shorter test (~1 hour vs. 3+ hours)
  • You want the flexibility to re-take the test with minimal wait time

Choose IELTS if…

  • Your target institution requires IELTS specifically
  • You need scores for immigration (Canada PR, Australia, UK)
  • You prefer a test with a human examiner for the speaking section
  • You are applying to UK universities that only accept IELTS
  • You want the widest global recognition

Choose TOEFL if…

  • Your target US university prefers or requires TOEFL
  • You are stronger at academic reading and listening tasks
  • You prefer typing your speaking responses (no face-to-face examiner)
  • You want a well-established test with decades of acceptance history
  • You are comfortable with a 2-hour test format

4-Week DET Preparation Strategy

A structured plan to go from first exposure to test-ready confidence in four weeks.

Week 1: Diagnose and Learn

  • Take the free Duolingo practice test to establish your baseline score.
  • Identify your weakest subscores: Literacy, Comprehension, Conversation, or Production.
  • Familiarise yourself with every question type: Read and Complete, Read Aloud, Listen and Type, Read and Select, Write About the Photo, Speak About the Photo, Interactive Reading, and Interactive Listening.
  • Study the test rules thoroughly — understand what is and is not allowed (no headphones, no second monitor, no leaving the frame).
  • Begin a daily vocabulary routine: aim for 15–20 new words per day using spaced repetition.

Weeks 2–3: Build Performance

Reading & Vocabulary

  • Practise Read and Complete (cloze) passages daily. Focus on collocations, not just individual words.
  • Read editorials from publications like The Economist, BBC, or The Atlantic to build contextual vocabulary.
  • Drill Read and Select questions to sharpen your ability to distinguish real English words from invented ones.

Listening

  • Practise Listen and Type with varied accents (American, British, Australian).
  • Use podcasts at 1.25x speed to train your ear for fast, natural speech.
  • Focus on spelling accuracy — the DET penalises misspellings in dictation tasks.

Writing

  • Practise Write About the Photo under a strict 1-minute timer.
  • Work on sentence variety: mix simple, compound, and complex sentences.
  • Use transition words naturally. Avoid memorised templates; the adaptive system values authentic language.

Speaking

  • Record yourself answering Speak About the Photo prompts. Review for clarity, pacing, and filler-word reduction.
  • Practise speaking for exactly 90 seconds on random topics to build time awareness.
  • Focus on pronunciation clarity over accent — the DET assesses intelligibility, not native-like accent.

Interactive Tasks

  • Practise Interactive Reading (completing sentences in a longer passage) and Interactive Listening (answering questions about a conversation).
  • Build stamina for sustained focus, as these tasks require concentration across multiple sub-questions.

Final Week: Simulate and Stabilise

  • Take two full-length practice tests under real conditions: quiet room, webcam on, no breaks.
  • Review mistakes methodically. Categorise errors by question type and address patterns.
  • Fine-tune your test-day setup: confirm your internet speed, webcam angle, lighting, and ID readiness.
  • Reduce study intensity two days before the test. Rest, sleep well, and avoid cramming.
  • Prepare your testing environment the night before: clean desk, closed browser tabs, charged laptop.

Test-Day Checklist

  • Government-issued photo ID (passport, national ID, or driver’s licence) ready on your desk
  • Stable internet connection (wired is preferable; minimum 2 Mbps up/down)
  • Working webcam and microphone — test both before starting
  • Quiet, well-lit, private room with no one else present
  • Clean desk: no phones, books, notes, or secondary screens
  • Browser: use the latest version of Chrome on a laptop or desktop (tablets and phones are not allowed)
  • Close all other applications and browser tabs
  • Do not wear headphones or earbuds
  • Keep your eyes on the screen throughout the test — looking away repeatedly may invalidate your results
  • Have water nearby (but no food during the test)

Frequently Asked Questions

Quick answers to the most common questions about the Duolingo English Test in 2026.

The Duolingo English Test is an online, computer-adaptive English proficiency exam. It takes approximately 1 hour to complete, delivers certified results within 48 hours, and is accepted at over 6,500 programmes worldwide. You take the test at home on your own computer — no test-centre visit is required.

The DET costs US $65, which is approximately ₹6,706 at prevailing exchange rates. This makes it roughly 65% cheaper than IELTS (₹19,000) and 56% cheaper than TOEFL (₹15,254). You can also purchase additional score sends at no extra cost — DET allows unlimited free score sends to institutions.

Over 6,500 programmes accept the DET, including Ivy League institutions in the US (Yale, Columbia, MIT), Canada’s U15 universities (University of Toronto, UBC, McGill), and many UK and Australian institutions. Acceptance has grown significantly since 2020. Always verify directly with your target programme, as policies change each admission cycle.

The DET is scored on a scale of 10 to 160 in 5-point increments. You receive an overall score plus four subscores: Literacy (reading + writing), Comprehension (reading + listening), Conversation (listening + speaking), and Production (writing + speaking). These subscores help universities evaluate specific language abilities beyond the overall number.

No. The DET is not accepted by Immigration, Refugees and Citizenship Canada (IRCC) for Express Entry or permanent residency applications. For Canadian immigration pathways, you need to use IELTS General Training, CELPIP, or PTE Core. The DET is accepted by many Canadian universities for study permit applications, but not for immigration.

DET scores are typically valid for 2 years from the date you took the test. However, individual institutions may have their own validity policies — some may accept scores only within 18 months, while others may extend validity. Always check your target programme’s specific requirements.

The DET is a different format, not objectively easier or harder than IELTS or TOEFL. Its computer-adaptive design means the test adjusts question difficulty based on your responses — if you answer correctly, questions get harder, and vice versa. Some test-takers find the 1-hour duration and at-home delivery more comfortable than sitting for a 3-hour exam at a test centre, but the adaptive algorithm ensures the test accurately measures your proficiency level regardless.
