If you’re planning to study abroad, you’ve probably come across the Duolingo English Test during your research. This modern alternative to IELTS or TOEFL is gaining attention for its affordability, flexibility, and fast results. But what exactly is the test, how does it work, and is the Duolingo certificate truly recognized by universities worldwide?
In this guide, we’ll explore its format, validity, and its acceptance in 2025—so you can make an informed decision about whether it’s the right English proficiency test for you.
Why the Duolingo English Test Appeals to Students
The popularity of the Duolingo English Test among students comes down to several key advantages:
- Convenience – No travel, no test center booking, and flexible scheduling.
- Affordability – At $70–80 USD, it’s significantly cheaper than IELTS or TOEFL.
- Speed – Results arrive in about 48 hours, perfect for last-minute applications.
- Unlimited Score Sending – Send your Duolingo certificate to as many institutions as you like for free.
- Fairness – Adaptive testing ensures a personalized difficulty level, reducing test fatigue.
Therefore, these benefits make it an ideal option for many —especially if applying to institutions that already list DET as an accepted test.
Understanding the Duolingo English Test
The Duolingo English Test (often shortened to DET) is a computer-based English proficiency exam that evaluates your reading, writing, listening, and speaking skills. Unlike traditional tests that require booking a test center appointment, the DET is entirely online from your home.
Its short format and online delivery make DET more accessible than most English proficiency exams. The difficulty of each question changes depending on your previous answer—meaning the test can assess your ability in less time than other exams.
| Feature | Details |
| Test Duration | About 60 minutes |
| Delivery Method | Online from home |
| Result Timeframe | Usually within 48 hours |
| Cost | Around $70–80 USD |
| Score Range | 10–160 points |
How Long Is the Duolingo Certificate Valid?
The Duolingo certificate—the official score report you receive after taking the DET—is valid for two years from your test date. Once it expires, you can’t share it with universities, and you’ll need to retake the exam for a new score. If your program starts after the expiry date, plan your test timing carefully to avoid paying for a retake.
Test Structure, Content, and Scoring
The Duolingo English Test (DET) includes three key parts, each designed to evaluate different aspects of your English proficiency:
- Setup and Onboarding – Before starting, you’ll verify your identity using a valid government-issued ID, complete a camera and microphone check, and ensure your internet connection meets the requirements. You’ll also review test rules, such as no headphones, note-taking, or leaving the camera frame.
- Adaptive Test (Graded) – This is the core 45-minute section. It covers:
- Reading – Selecting real English words from a list, filling in missing letters, or reading passages.
- Listening – Identifying correct pronunciations or transcribing short audio clips.
- Writing – Typing short and long responses to prompts.
- Speaking – Responding to questions or images aloud.
The difficulty adapts to your answers, creating a personalized test experience.
- Video and Writing Sample (Unscored) – In the final 10 minutes, you’ll record a 1–3 minute video and write a short essay. These aren’t scored but are sent to institutions alongside your results to showcase your communication style.
Scoring
Your performance in the adaptive section is converted into an overall score ranging from 10 to 160, in 5-point increments. Scores are also reported in four subscores: Literacy, Comprehension, Conversation, and Production. Many top universities require a score between 105 and 125 for admission.
Is the Duolingo Certificate Accepted Worldwide?
Yes—acceptance of the Duolingo English Test has expanded rapidly, with more than 5,500 institutions across over 70 countries recognizing it for admissions in 2025.
Examples include:
- United States: Columbia University, University of Chicago, New York University
- Canada: University of Toronto, McGill University, University of British Columbia
- Ireland: Trinity College Dublin, University College Dublin
- Australia & New Zealand: University of Sydney, University of Auckland

- United Kingdom: Many universities accept DET, but it is not valid for UK student visa applications—IELTS for UKVI is usually mandatory.
