Duolingo English Test format: one hour, adaptive, thirteen question types
The Duolingo English Test takes about an hour of uninterrupted time: five minutes of setup and ID verification, a 45-minute adaptive assessment, and ten minutes of writing and speaking samples. It is computer-adaptive, so the difficulty changes as you answer and the number of questions varies.
The hour, in three parts
| Part | Time | What happens |
|---|---|---|
| Setup and ID verification | 5 minutes | Camera, speaker and microphone check; government photo ID; phone camera set up; rules |
| Adaptive assessment | 45 minutes | The scored question types, adapting to your performance |
| Writing and speaking samples | 10 minutes | Unscored by the engine, but sent to every institution that receives your results |
The setup now includes positioning your phone camera to record your computer. It is a second recording angle for security, and it is a step candidates are regularly unprepared for — have the phone and a way to prop it up ready before you start.

Read and Select is by far the most frequent item, at 15 to 18 appearances — the one where you decide which displayed words are real English and which are invented. It is worth more of your preparation than its length suggests.
What adaptive means here
- Difficulty varies within the test, so some questions will feel easier or harder than others. Duolingo says plainly that this is normal.
- Length varies. The engine serves more or fewer questions depending on how confident it is in your score.
- Questions are drawn from a very large pool, so you are unlikely to meet the same question twice however many times you sit it.
Two consequences. A hard-feeling test is usually a good sign, not a bad one — and there is no point counting questions to gauge progress, because there is no fixed number to count towards.
You cannot go back
Once an item is submitted it is gone. There is no review screen, no flagging and no second pass — which is the opposite of the GRE and the GMAT. Everything you want to check, you check before you submit, and then you move on without dwelling on it.
The samples are not scored, and are read anyway
The Writing Sample and Speaking Sample at the end are not marked by the scoring engine, but they are sent to every institution that receives your results — and admissions staff do watch and read them.
- Sit somewhere quiet and reasonably well lit.
- Dress as you would for a short interview.
- Answer as you would to a person, not to a microphone.
- Treat them as part of the application, because that is what they are.
