DET vs IELTS: Complete 2026 Comparison (Format, Cost, Difficulty, Acceptance)

The short answer: take the DET if your target universities accept it. It costs $70 vs $215–$310, takes 60 minutes vs nearly 3 hours, and delivers results in 48 hours vs up to 13 days. But IELTS is mandatory for UK visas, Canadian PR, and Australian immigration — and that changes everything. Here is the complete, fully updated 2026 comparison.

DET Test Format: All 13 Question Types (2026 — Fully Updated)

The DET is a single 60-minute session taken from home, structured in three parts. As of the July 1, 2025 format update, the test contains 13 question types. Read Aloud and Listen, Then Speak were removed; Interactive Speaking was added; and Interactive Listening was significantly expanded.

A secondary smartphone camera is now mandatory (introduced September 2025), positioned to capture your full screen and keyboard throughout the session.

Part 1: Setup (~5 minutes)

ID verification, system check, webcam setup, and secondary camera positioning. The test does not begin until both cameras are confirmed.

Part 2: Adaptive Section (~45 minutes)

All scored question types appear in this section, mixed together and adapting in difficulty based on your real-time performance (IRT algorithm). The 13 question types are:

Question Type Skill What You Do Frequency
Read and Select Reading / Vocabulary A single word appears for 5 seconds. Click Yes (real English word) or No (invented word). Tests vocabulary recognition. 15–18 times
Fill in the Blanks Reading / Vocabulary A short passage with missing words — select the best word from options to complete each blank. Tests vocabulary and reading comprehension in context. 6–9 times
Read and Complete Reading / Literacy Sentences with incomplete words — type the missing letters to complete the word. 20 seconds per sentence. Tests spelling and vocabulary at word level. 3–6 times
Interactive Reading Reading / Comprehension A passage followed by multiple question subtypes. Appears once as a set. Subtypes include: Complete the Sentence, Complete the Passage, Highlight the Answer (click relevant text), Identify the Idea (summarize in one sentence), and Title the Passage. 1 set (multiple questions)
Listen and Type Listening / Literacy A short audio clip plays (with up to 3 replays). Type exactly what you hear. Tests dictation accuracy and spelling. Minor spelling errors are not penalized if meaning is preserved. 6–9 times
Interactive Listening Listening / Comprehension Two full conversations — one casual (with a classmate) and one formal (with a professor). Each lasts ~6–7 minutes. You play the role of the student. Subtypes include: Listen and Complete (fill blanks while listening), Listen and Respond (choose best response to the conversation), and Summarise the Conversation. 2 conversations (multiple questions each)
Write About the Photo Writing / Production An image appears. Write one or more sentences describing it within 60 seconds. Appears 3 times consecutively. Affects Writing, Literacy, and Production subscores. 3 times
Interactive Writing Writing / Literacy / Production Two-phase writing task: Phase 1 — write a response to a prompt (5 minutes, ~120 words). Phase 2 — respond to a follow-up prompt while your Phase 1 answer remains visible (3 minutes, ~80 words). Phase 2 follow-up is pre-written, not AI-generated from your response. 1 time
Speak About the Photo Speaking / Production An image appears. Describe it verbally into your webcam. 1–3 minutes (minimum time requirement removed July 2025). Appears once. 1 time
Read, Then Speak Speaking / Comprehension Read a short written prompt, then respond verbally — speak about the topic for 1–3 minutes. Appears once. Minimum time requirement removed July 2025. 1 time
Interactive Speaking Speaking / Conversation NEW as of July 1, 2025 (replaced Read Aloud and Listen, Then Speak). A multi-turn spoken conversation — 6–8 questions that build on each other. 35 seconds to record each response. Tests spontaneous conversational ability and pragmatic language use. 1 set (6–8 questions)

Part 3: Sample Section (~10 minutes — sent to universities)

The final two tasks are unscored by the adaptive algorithm but contribute to your subscores and are sent directly to every institution you share your result with. Admissions officers read and view them.

Task Time What You Do
Writing Sample 5 minutes Write an essay responding to an academic or personal prompt. 30 seconds of preparation time before writing begins. Aim for 100–130+ words. Minimum time requirement removed July 2025 — submit when ready.
Speaking Sample 1–3 minutes Respond verbally to a written prompt. Speak directly into your webcam. Minimum time requirement removed July 2025.

Question types removed from the DET (no longer appear):

  • Read Aloud — removed July 1, 2025
  • Listen, Then Speak — removed July 1, 2025
  • Read, Then Write — removed in an earlier update (pre-2025)

IELTS Academic Format (2026)

IELTS is divided into four separately timed sections — three taken in sequence on the same day, with Speaking usually scheduled separately (within 7 days before or after the written test):

Section Duration Content Questions
Listening 30 min (+10 min paper transfer) 4 recorded sections: 2 conversations + 2 monologues/lectures. Heard once only. Accents include British, Australian, American, NZ English. 40 questions
Reading 60 min 3 long academic passages (~2,750 words total) from journals, books, magazines. Question types: True/False/Not Given, matching headings, sentence completion, multiple choice, diagram labelling. 40 questions
Writing 60 min Task 1: Describe a graph/chart/diagram (150+ words, ~20 min). Task 2: Academic essay on a social/global topic (250+ words, ~40 min). Task 2 carries double the weight of Task 1. 2 tasks
Speaking 11–14 min Live interview with a certified examiner. Part 1: Introduction and familiar topics. Part 2: Task card — 1 min prep, 1–2 min monologue. Part 3: Abstract discussion linked to Part 2. Scheduled within 7 days of the written test. 3 parts

Unlike the DET, IELTS uses fixed question sets — every candidate at the same test sitting answers identical questions. The format has not changed significantly since 2016, making it highly predictable and well-documented for preparation purposes.

Skill-by-Skill Comparison (2026 DET Format)

Speaking: Interactive AI Conversation vs. Live Human Interview

This is the most significant experiential difference between the two tests — and it changed substantially with the July 2025 DET update.

DET Speaking (2026) now spans four question types: Speak About the Photo (1 time), Read, Then Speak (1 time), Interactive Speaking (1 set of 6–8 questions), and the Speaking Sample (1–3 minutes sent to universities). The new Interactive Speaking task replaced Read Aloud and Listen, Then Speak — it presents a multi-turn spoken dialogue where each of the 6–8 questions builds on the previous one, with 35 seconds to respond to each. This tests spontaneous conversational ability rather than just pronunciation or scripted reading. All responses are recorded and AI-scored, with human proctors reviewing the session for integrity.

IELTS Speaking is a live 11–14 minute interview with a certified examiner. Three parts cover familiar topics, a prepared monologue, and abstract discussion. Human examiners assess fluency, coherence, lexical resource, grammatical range, and pronunciation in real time. Natural conversational flow, clarification, and follow-up questions from the examiner are part of the format.

Verdict: The DET's 2025 update significantly closed the gap with IELTS on speaking — Interactive Speaking now tests real conversational ability, not just reading aloud. That said, IELTS Speaking still involves genuine human interaction. Candidates who perform better with live conversation tend to score higher on IELTS Speaking; those comfortable with short, rapid spoken responses to a camera tend to favor DET.

Writing: Short Adaptive Tasks vs. Extended Academic Essays

DET Writing (2026) spans three question types: Write About the Photo (3 times, 60 seconds each), Interactive Writing (two-phase, 5 min + 3 min), and the Writing Sample (5-minute essay sent to universities). The total writing time is approximately 18 minutes distributed across the session. All writing is typed; a writing sample of 100–130+ words is expected for the essay. The Writing Sample is read directly by admissions officers in addition to being algorithmically scored.

IELTS Writing is a single 60-minute block: Task 1 (graph/diagram description, 150+ words) and Task 2 (essay, 250+ words). Task 2 carries twice the scoring weight. Marked by trained human examiners against official band descriptors covering task achievement, coherence and cohesion, lexical resource, and grammatical range and accuracy.

Verdict: DET writing is distributed and shorter per task — better for fast typists under time pressure. IELTS Writing rewards candidates who plan, structure, and develop extended academic arguments with more dedicated time.

Reading: Integrated Adaptive Tasks vs. Three Long Passages

DET Reading (2026) uses four question types: Read and Select (15–18 single-word questions, 5 seconds each), Fill in the Blanks (6–9 questions, passage-level cloze), Read and Complete (3–6 questions, word-level spelling completion), and Interactive Reading (one multi-question passage set with 5 subtypes including Highlight the Answer and Title the Passage). Reading tasks are distributed throughout the adaptive section, not isolated in one block.

IELTS Reading is 60 dedicated minutes with three long academic passages and 40 questions. Requires sustained analytical focus, the ability to skim and scan large volumes of text, and proficiency with diverse academic question types. All passages carry the same fixed difficulty for every candidate.

Verdict: DET reading tests vocabulary recognition and passage comprehension through shorter, varied tasks. IELTS reading demands sustained concentration on dense academic text. Candidates with strong academic reading stamina typically score well on IELTS; those with broader vocabulary range but lower endurance for long passages often score better on DET reading tasks.

Listening: Conversational Simulation vs. Scripted Recordings

DET Listening (2026) uses two question types: Listen and Type (6–9 short clips with dictation, up to 3 replays each) and Interactive Listening (two full conversations — one casual with a classmate, one formal with a professor — each ~6–7 minutes long, with Listen and Complete, Listen and Respond, and Summarise the Conversation subtypes). The Interactive Listening format simulates real academic social situations: navigating a conversation with a peer and interacting respectfully in an academic context with a professor.

IELTS Listening presents four recordings played once only, totalling approximately 30 minutes of audio. Sections progress from social conversations to academic monologues and lectures. Diverse accents are used intentionally. No replays; careful note-taking during playback is essential.

Verdict: DET Listening is more conversational and interactive, especially after the 2025 update. IELTS Listening is more traditional and academic, but heard only once — replay not available. DET's up-to-3-replay option per clip reduces pressure but rewards accuracy.

Is the DET Easier Than IELTS?

The honest answer is: it depends on the individual. The correlation between DET and IELTS scores is approximately 0.65 according to Duolingo's official technical manual — meaning significant individual variation exists. Many test-takers score 0.5–1 full band higher on one test than the other despite having the same underlying proficiency.

You will likely score better on DET if you... You will likely score better on IELTS if you...
Are comfortable speaking to a camera without live interaction Perform better in natural face-to-face conversation
Are a fast, accurate typist Prefer writing with more time to plan and structure
Have a wide vocabulary range Excel at sustained reading of long academic texts
Adapt quickly to varied, unpredictable question types Prefer predictable, well-documented question formats
Perform well in short, high-intensity bursts Maintain high performance over 3 hours of structured tasks
Have access to a stable home testing environment Prefer supervised test center environment for focus

Practical recommendation: Take the official free DET mock test at englishtest.duolingo.com/practice before choosing. Your mock score is the strongest predictor of your certified result. If you score at or near your target, the DET is your most cost-effective path forward.

DET vs IELTS Acceptance: Where Each Test Works (2026)

Purpose / Destination DET IELTS Notes
US University Admissions ✅ 97 of top 100 US universities ✅ Yes DET effectively equal to IELTS for US admissions; verify specific programs
Canadian University Admissions ✅ Most major institutions ✅ Yes Verify by department — some still prefer IELTS/TOEFL
UK University Admissions ⚠️ Some — growing but inconsistent ✅ Strongly preferred Verify each university individually; IELTS dominant in UK
Australian University Admissions ⚠️ Some — varies by institution ✅ Yes IELTS dominates; DET acceptance is growing
European University Admissions ⚠️ Growing — inconsistent by country ✅ Broadly accepted Germany, Netherlands, France increasingly accept DET; verify each
UK Visa (SELT) ❌ Not accepted ✅ IELTS for UKVI mandatory No alternative — IELTS UKVI is the only accepted SELT for most UK visa types
Canadian PR (Express Entry / SDS) ❌ Not accepted by IRCC ✅ Yes IRCC rejects DET even if equivalent score exceeds requirement
Australian Visa ❌ Not accepted ✅ Yes Immigration and admissions requirements are independent — verify both
Professional Registration (medical, nursing) ❌ Rarely accepted ✅ Standard requirement Most professional licensing bodies have not adopted DET

DET to IELTS Score Conversion (2026 — Updated Chart)

There is no official direct score conversion between DET and IELTS. However, Duolingo publishes official comparative data based on candidates who took both tests. The table below reflects the most current verified equivalency data per Duolingo's official July 2025 technical manual update. Note that Duolingo revised its conversion data in 2025 — the new figures are more conservative than pre-2025 sources. Many older articles still cite outdated equivalencies (e.g. claiming DET 125 = IELTS 7.5), which is no longer accurate.

DET Score IELTS Equivalent (approx.) CEFR Level Typical Requirement Context
160 9.0 C2 Mastery Highest research programs; exceptional proficiency
145–155 8.5 C2 Top-tier postgraduate, law, medicine
130–140 7.5–8.0 C1–C2 Competitive postgraduate and research programs
120–125 7.0 C1 Standard requirement for most postgraduate programs globally
110–115 6.5 B2–C1 Competitive undergraduate programs; many graduate programs
100–105 6.0 B2 Standard undergraduate admission; pathway programs
90–95 5.5 B1–B2 Foundation courses; conditional admissions
<90 ≤5.0 B1 or below Below academic threshold for most degree programs

Always check the specific DET minimum your target institution requires directly — universities set their own requirements independently and do not use conversion tables for admissions decisions. The correlation between DET and IELTS scores is approximately 0.65, meaning individual variation is significant.

Conclusion: DET vs IELTS — The 2026 Verdict

For the majority of international students applying to universities in the US, Canada, Australia, and Europe for academic admissions, the Duolingo English Test is the stronger choice in 2026. The July 2025 format update made it more rigorous — Interactive Speaking and the expanded Interactive Listening format now test real communicative competence, not just isolated language skills — while keeping the cost at $70 and the duration at 60 minutes.

IELTS remains mandatory for anyone who needs a UK visa, Canadian permanent residency, Australian immigration status, or professional licensing. For these purposes, there is no cheaper substitute. If immigration is part of your plan now or in the near future, IELTS is the correct investment.

The best practical first step for most students: take the free DET mock test at englishtest.duolingo.com/practice. If your score is at or near your target, book the DET. If you significantly underperform or your target institution doesn't accept it, take IELTS. Either way — arrive prepared.
