What is the Duolingo Test Validity?
The Duolingo English Test (DET) has gained widespread acceptance among universities as an alternative to traditional language proficiency tests like TOEFL and IELTS. Designed for accessibility and convenience, DET allows students to prove their English proficiency through an online, on-demand test that can be taken from anywhere in the world.
In this blog, we explore the test’s growing validity in the academic world, acceptance criteria across institutions, and how long the scores remain valid for university admissions.
What is the Duolingo English Test?
The Duolingo English Test is a digital language proficiency test that assesses reading, writing, speaking, and listening skills in a compact 45–60 minute format. It can be taken from home using a computer with a webcam and microphone, making it a flexible and affordable option—especially for students in remote or low-resource settings.
Global Acceptance of the DET
Thousands of institutions worldwide now recognize the Duolingo English Test as a valid measure of English proficiency. Notable universities in the U.S., Canada, the UK, Australia, and parts of Europe and Asia accept DET scores for undergraduate and graduate admissions.
Acceptance varies by institution, so students should check directly with their target schools. Some universities use DET as a standalone requirement, while others accept it as a supplementary test or during specific admission cycles.
Duolingo Test Scoring and Interpretation
DET uses a score scale from 10 to 160, with different score bands corresponding to various levels of English proficiency:
- 160–130: Excellent – comparable to IELTS 8.0+
- 129–110: Very Good – comparable to IELTS 7.0–7.5
- 109–90: Good – suitable for most undergraduate admissions
- Below 90: Limited proficiency – may require remedial language support
Most universities require a minimum score ranging from 100 to 120, depending on the program level.
Score Validity: How Long Are DET Scores Accepted?
DET scores are valid for two years from the test date. After this period, scores expire and cannot be used for admissions. Students should plan their test dates strategically to ensure their scores remain valid when applying and enrolling.
Tips for Students Taking the DET
- Familiarize yourself with the test format and practice with official materials.
- Ensure your test environment meets technical requirements (quiet space, webcam, mic, and stable internet).
- Use available practice resources to improve performance and comfort with the interface.
- Do not attempt to cheat—integrity violations can lead to invalidated results.
Conclusion
The Duolingo English Test is now a legitimate and practical choice for students seeking admission to English-speaking universities. With growing global recognition, a quick turnaround time for results, and high accessibility, DET is reshaping how students demonstrate language proficiency. However, students must still verify institutional requirements and plan ahead to ensure their scores remain valid throughout the admissions process.
