Duolingo English Test format 2026: every question type, timing and how adaptivity works
The Duolingo English Test (DET) is an online English test of about one hour that you take at home on your own computer. Instead of four long sections, it gives you many short questions of 13 types, mixed so that most of them test more than one skill. Part of the test is adaptive: when you answer well, the next questions get harder. At the end you get an overall score from 10 to 160 and four subscores: Reading, Listening, Writing and Speaking.
Everything below follows Duolingo’s own DET Question Guide (2026), the Scoring Guide for Teachers (2026) and the DET help center, checked on 5 November 2026. If a book or video shows you Read Aloud, Listen and Select, Listen, Then Speak or Read Then Write, it describes an older version of the test: none of those are in the 2026 guide.
How the hour is organized
The help center splits the test into three stages:
- Setup (onboarding). You check your camera, speakers and microphone, show your government photo ID, scan your room and ears with your phone, and set the phone up to film your screen and keyboard. This takes real time, so plan for it.
- The adaptive part. Reading and listening questions, plus the photo tasks and Interactive Writing and Speaking. The difficulty of the adaptive questions changes with your answers.
- Writing Sample and Speaking Sample. Two longer answers at the end. Universities that receive your results can read the Writing Sample and watch a video of your Speaking Sample.
You need about one hour of uninterrupted time. You may not take notes, wear headphones or leave the camera frame.
All 13 question types at a glance
| Question type | What you do | Time | How many | Subscore | Adaptive |
|---|---|---|---|---|---|
| Read and Select | decide whether a word on the screen is a real English word | 5 s per word | 15–18 | Reading | yes |
| Fill in the Blanks | type the missing ending of one word in a sentence | 20 s | 6–9 | Reading | yes |
| Read and Complete | type the missing endings of words in a paragraph | 3 min | 3–6 | Reading | yes |
| Listen and Type | type a sentence of up to 20 words that you hear (up to 3 plays) | 1 min | 6–9 | Listening | yes |
| Interactive Reading | six questions about one passage | 7 or 8 min per passage | 2–3 passages | Reading | yes |
| Interactive Listening | complete sentences about a scenario, take part in a conversation, summarize it | 6 min 30 s + 75 s | 2–3 scenarios | Listening (summary also Writing) | yes |
| Write About the Photo | describe a photo in writing | 1 min | 3 | Writing | no |
| Interactive Writing | answer a question, then a follow-up on a new aspect of the topic | 30 s prep + 5 min + 3 min | 1 | Writing | no |
| Speak About the Photo | describe a photo aloud | 20 s prep + 90 s | 1 | Speaking | no |
| Read, Then Speak | speak about a written question with bullet points | 20 s prep + 90 s | 1 | Speaking | no |
| Interactive Speaking | answer 6–8 spoken questions on two topics | 35 s per answer | 1 set | Speaking | yes |
| Writing Sample | write about an experience or an opinion | 30 s prep + 5 min | 1 | Writing | no |
| Speaking Sample | speak about an experience or an opinion, on video | 30 s prep + 3 min | 1 | Speaking | no |
The help center’s own test-structure page lists two sets each of Interactive Reading and Interactive Listening, while the 2026 Question Guide says two or three. Expect two, and do not panic if a third appears.
The reading questions
Read and Select tests vocabulary size at speed. One word appears at a time; you click Yes if it is a real English word, No if it is not. The fake words are built to look real. If you do not answer in 5 seconds, the item is marked wrong. Strategy and examples are in Read and Select: how to spot the fake words.
Fill in the Blanks and Read and Complete are both C-tests: you see the first half of a word and type the rest. Fill in the Blanks gives you one word in one sentence; Read and Complete gives a whole paragraph in which the title, the first and the last sentence are untouched. Spelling must be exact. See Fill in the Blanks and Read and Complete.
Interactive Reading builds six questions around one passage, in a fixed order: Complete the Sentences (choose 3–10 missing words), Complete the Passage (choose the missing sentence), two Highlight the Answer questions (drag over the answer in the text), Identify the Idea and Title the Passage. Every test has at least one narrative passage and one that gives information. The full walk-through is in Interactive Reading: the six steps.
The listening questions
Listen and Type is dictation: up to 20 words, up to three plays, one minute. You get partial credit, and words, spelling and punctuation all count. See Listen and Type.
Interactive Listening is a short university situation: one conversation is between two students, one between a student and a professor. You first listen to the scenario and complete three or four sentences about it (Listen and Complete), then take part in the conversation by choosing the best reply 5–6 times (Listen and Respond), and finally write a summary in 75 seconds. The first two parts share one 6 minute 30 second timer. Details in Interactive Listening.
The writing and speaking questions
None of the photo or sample tasks is adaptive; Interactive Speaking is the only adaptive speaking task. All open answers are scored by AI on content, discourse coherence, grammar and lexis; speaking adds fluency and pronunciation. Both UK and US spelling are accepted, and any standard accent is fine if it is easy to understand.
- Writing: three photo descriptions of one minute each, one Interactive Writing task in two parts, the Writing Sample, and the two summaries from Interactive Listening. Model answers: DET writing tasks.
- Speaking: one photo, one Read, Then Speak, one set of Interactive Speaking questions asked by an animated character, and the Speaking Sample. You cannot re-record an answer. Model answers: DET speaking tasks.
How adaptivity changes your strategy
Adaptivity means your score is not the number of correct answers. Duolingo says plainly that the test does not give each question type a fixed percentage of the score. The number of questions can also vary: the test gives more or fewer items depending on how confident the scoring engine is about your level. Three practical consequences:
- Hard questions are a good sign. If Read and Complete suddenly feels difficult, the test has probably moved you up. Do not let it shake you.
- Never leave a gap. Duolingo’s help center says you are not penalized more for a wrong answer than for skipping it. In Read and Complete a blank and a wrong word score the same, so a guess can only help.
- Do not try to game the order. You cannot go back to earlier questions, so treat each one as final and move on.
What changed in 2024–2025
| When | Change |
|---|---|
| 2024 | Interactive Writing added: two linked prompts instead of one |
| 1 July 2024 | Separate Reading, Listening, Writing and Speaking subscores, plus four combined subscores |
| 1 July 2025 | Interactive Speaking added and replaced Listen, Then Speak; Read Aloud removed to keep the test the same length |
| 1 July 2025 | Interactive Listening expanded: the scenario is now heard rather than read, and Listen and Complete was added at the start |
| 2025 | Phone-based room scan and, later, an ear scan added to the setup |
Combined subscores from before July 2024 are not comparable with the new ones, so if an older friend tells you their “Literacy” score, it was calculated differently. For how the scale works today, see Duolingo English Test scores.
Common mistakes about the format
- Practicing removed tasks. Read Aloud and Listen, Then Speak are gone. Time spent on them is time not spent on Interactive Speaking, which is now the largest speaking task.
- Ignoring setup. A failed room scan or a phone that falls over can end a test. Read fee, registration and how to take it at home before test day.
- Treating the samples as unscored. Both the Writing Sample and the Speaking Sample count toward your subscores, and universities see them.
- Running out of time in Interactive Reading. The 7–8 minutes cover all six questions, not each one.
Try the whole format in the Nomto room
The fastest way to learn this structure is to go through it once under time pressure. The Nomto practice tests cover every 2026 question type, including Interactive Speaking, and estimate your overall score and four subscores on the 10–160 scale. Reading and listening answers are checked at once; speaking and writing get a review with corrections and a model answer. Use Duolingo’s free official Practice Test as well for a second estimate. For a full study schedule, see how to prepare for the Duolingo English Test.
Common questions
How long is the Duolingo English Test? About one hour, including setup. The number of questions varies slightly because the test is adaptive.
How many sections does the DET have? It is not split into four skill sections. Questions of 13 types are mixed, and most feed one or two subscores.
Is there a break? No. You need about one hour without interruption.
Can I go back to a question? No. Each answer is final once you move on.
Does the DET have an essay? The Writing Sample is the closest thing: 5 minutes to write about an experience or opinion, and universities read it.
