🌍 Who Takes the Duolingo English Test—and For What Purpose?

The Duolingo English Test (DET) has quickly become one of the most widely used English proficiency exams in the world. Affordable, online, and accepted by thousands of universities, it attracts a large and diverse group of learners. But who exactly makes up this community of test takers? And why are so many students choosing the DET over traditional exams like TOEFL or IELTS?
Recent research sheds light on these questions, offering useful insights for both students and institutions.
🌐 A Global Snapshot
Test takers come from more than 100 different countries, reflecting just how international the DET has become.
- Asia leads the way, with roughly 6 in 10 test takers coming from the region.
- Students from North America and Europe also make up a sizeable share.
- On a country level, India and China account for the largest groups, showing how strong the demand for English certification is in those nations.

🎓 Main Reasons Students Choose the DET
The overwhelming majority—around 90%—take the DET to apply for higher education programs abroad. Whether applying to undergraduate or graduate studies, students see the DET as:
- A faster and more flexible alternative to traditional testing
- An affordable option that avoids travel and scheduling barriers
- A widely accepted credential that opens the door to thousands of institutions
In short, the DET is popular because it balances convenience with reliability.

📊 What the Score Data Tells Us
DET scores are reported across four skill areas: literacy, comprehension, conversation, and production. These categories give universities a clear sense of how prepared an applicant is for academic life.
Research on score patterns shows that:
- The test produces balanced results across all skills, rather than favoring one over another.
- Universities can confidently interpret DET scores as indicators of real language proficiency.
For students, this means that doing well on the DET is more than just achieving a number—it’s demonstrating readiness for study in English.
👩🎓 First-Timers and Retakers
Another interesting finding relates to who is taking the exam:
- Most test sessions (about two-thirds) are from first-time test takers.
- Repeat test takers usually score a bit lower, since many are retaking in hopes of raising their score.
The takeaway? Preparation before your first attempt really matters. Entering the test with confidence and a clear study plan gives you the best chance at reaching your target score without needing a second try.
✅ A Focus on Fairness and Trust
One strength of the DET is its commitment to transparency. By publishing detailed research on demographics and score properties, the test shows that:
- Students and teachers can understand how scores reflect proficiency.
- Institutions can see the DET as fair and equitable across diverse groups.
- Everyone benefits from clear evidence that the test measures what it promises.
This openness helps ensure that the DET continues to grow as a trusted global standard.
