What Is the Duolingo English Test?
The Duolingo English Test (DET) is a computer-adaptive English proficiency test you can take from home. It is accepted by over 5,000 universities worldwide, costs only $59, and takes about an hour to complete. Unlike IELTS or TOEFL, you do not need to visit a test center or wait weeks for results. Scores arrive within 48 hours.
The test uses adaptive technology that adjusts question difficulty based on your answers. If you answer correctly, questions get harder. If you make mistakes, they get easier. This means the test zeroes in on your true level faster than fixed-format exams.
DET Score Conversion: DET to CEFR
The DET scores on a 10 to 160 scale, which maps directly to the Common European Framework of Reference (CEFR). Use this table to understand what your DET score means:
| DET Score Range | CEFR Level | Proficiency | IELTS Equivalent |
|---|---|---|---|
| 10 - 55 | A1 - A2 | Basic | Below 3.0 |
| 60 - 85 | B1 | Intermediate | 3.0 - 5.0 |
| 90 - 115 | B2 | Upper Intermediate | 5.0 - 6.5 |
| 120 - 135 | C1 | Advanced | 6.5 - 7.5 |
| 140 - 160 | C2 | Expert | 7.5 - 9.0 |
DET Subscores Explained
Your DET score report includes an overall score plus four subscores. These help universities understand your specific strengths and weaknesses:
- Literacy: Reading and writing ability
- Comprehension: Reading and listening ability
- Conversation: Listening and speaking ability
- Production: Writing and speaking ability

How to Prepare for the Duolingo English Test
Getting a high DET score is about understanding the format and practicing strategically. Here is how to approach your prep:
1. Take the Free Practice Test
Duolingo offers an unlimited free practice test on their website. Take it right away to get a baseline score. The practice test follows the same adaptive format as the real test, so your practice score is a strong predictor of your actual result.
2. Focus on Your Weakest Subscore
After your first practice test, check which subscore is lowest. If your Production score is low, practice writing essays and recording voice responses. If Comprehension is low, do listening exercises every day.
3. Build Your Vocabulary
The Read and Select question requires knowing which words are real English. Study academic word lists and practice identifying real versus made-up words. A strong vocabulary directly boosts your Literacy and Comprehension subscores.
4. Practice Speaking Aloud
The speaking section asks you to describe photos and respond to open-ended prompts. Practice speaking for 60-90 seconds without pausing. Record yourself and listen for clarity, pronunciation, and fluency.
5. Improve Your Typing Speed
The writing questions are timed. If you type slowly, you will not be able to show your full writing ability. Practice typing at least 40 words per minute with accuracy. This alone can raise your Production score.
