Test Format, Scoring, and Strategy flashcards for Duolingo English Test (DET)

21 of 50 cards from the Test Format, Scoring, and Strategy deck — real questions with worked answers.

1. What is the overall structure of the Duolingo English Test (DET) in terms of length and delivery?

   It is a roughly one-hour, fully online, computer-adaptive English proficiency test taken on your own computer with a webcam, available on demand without a physical test center.

2. What does it mean that the DET is 'computer-adaptive'?

   The difficulty of each item adjusts in real time based on your performance: correct answers tend to lead to harder questions and incorrect answers to easier ones, so the test efficiently zeroes in on your ability level.

3. What are the three main phases of a DET session in order?

   (1) Quick Setup / onboarding and ID check, (2) the adaptive graded test section, and (3) the Video Interview and writing sample (ungraded by the algorithm but sent to institutions).

4. What computer equipment is required to take the DET?

   A desktop or laptop (not a phone or tablet) with a front-facing webcam, working microphone, and speakers, plus the supported Chrome or Edge/Duolingo browser.

5. What internet condition is required for a valid DET administration?

   A stable, reasonably fast internet connection for the entire session; the webcam, mic, and audio must stay on and the test cannot be paused once started.

6. What environmental requirements must the test room meet during the DET?

   A quiet, well-lit, private room where the test-taker is alone, with a clear desk, no other people, and no prohibited materials visible to the webcam.

7. How is the DET proctored?

   It uses asynchronous (recorded) human and AI proctoring: video, audio, and screen activity are recorded during the test and later reviewed for rule violations before a score is certified.

8. Name three behaviors that violate DET proctoring/integrity rules.

   Looking away from the screen repeatedly, speaking to or having another person present, using notes/phones/dictionaries, or leaving the camera's view—any of which can invalidate the test.

9. What identity verification is required before a DET begins?

   You must present a valid government-issued photo ID to the webcam and have your face photographed so the proctoring system can confirm your identity matches the score report.

10. How quickly are DET results typically delivered after testing?

    Certified results are usually available within about 2 days (48 hours) of completing the test, after proctoring review.

11. How are DET results sent to institutions, and is there a per-institution fee?

    Results can be sent to an unlimited number of institutions for free; you select recipient institutions and they receive your certified score report electronically.

12. What are the DET rules for retaking the test?

    You may take a limited number of certified tests within a rolling period (commonly up to 3 in 30 days); each retake is a fresh, independent test, and institutions usually see your most recent or highest valid scores per their policy.

13. What is the range of the DET overall score scale?

    The overall (total) score is reported on a scale from 10 to 160, in 5-point increments.

14. In what increments is the DET overall score reported?

    In increments of 5 points (e.g., 100, 105, 110), across the 10–160 scale.

15. What four subscores does the DET report?

    Literacy, Comprehension, Conversation, and Production—each also reported on the 10–160 scale.

16. Which DET subscore reflects the ability to read and write?

    Literacy.

17. Which DET subscore reflects the ability to understand written and spoken language (read and listen)?

    Comprehension.

18. Which DET subscore reflects the ability to listen and speak?

    Conversation.

19. Which DET subscore reflects the ability to write and speak?

    Production.

20. Why do the four DET subscores overlap in the skills they measure?

    Each subscore combines two of the four core skills (reading, writing, listening, speaking) across different pairings, so a single skill contributes to more than one subscore.

21. What overall DET score is commonly required by many U.S. undergraduate and graduate programs?

    A score around 105–120 is a common admissions threshold, with many competitive programs asking for roughly 120 and above.
