Duolingo English Test for Sri Lankan Students
Complete 2025 Guide: Registration, Format, Scores, and Which Universities Accept It
The Duolingo English Test (DET) is one of the most affordable and fastest English proficiency tests available to Sri Lankan students. This guide explains everything — from setting up your test at home to sending scores to universities abroad.
What Is the Duolingo English Test?
The Duolingo English Test is an online, adaptive English proficiency test developed by Duolingo, the language-learning company. Unlike IELTS or TOEFL, the DET is taken entirely at home on your own computer — there is no test centre, no invigilator in the room, and no need to travel. AI-powered proctoring monitors the session instead.
The test takes approximately one hour to complete and measures four sub-skills: Literacy (reading and writing), Comprehension (listening and reading), Conversation (speaking and writing), and Production (speaking and writing in open-ended tasks). Results are typically available within two business days, and you can send them to an unlimited number of institutions at no extra cost within 48 hours of receiving your result.
As of 2025, over 5,500 programmes at more than 3,000 institutions worldwide accept DET, including universities in the USA, Canada, Germany, Netherlands, and a growing number in the UK and Australia. However, acceptance is uneven — confirm with each target institution before registering.

Duolingo English Test Format
Adaptive Test
45 minutesA mix of question types covering reading, writing, speaking, and listening. Questions adapt to your level in real time. Types include: read-aloud sentences, listening comprehension fill-in-the-blank, multiple choice reading questions, open response writing, and production tasks where you describe images or speak from a prompt.
Video Interview
10 minutesOptional but sent to universities. You answer open-ended questions about yourself, your goals, and your opinions in unscripted one-way video responses. There is no examiner present — you record yourself. Universities use this to assess speaking fluency and communication style beyond the adaptive test score.
Writing Sample
5 minutesAn optional written essay response to a prompt, also sent to institutions alongside your score. You have five minutes to write a response of at least 50 words. This is separate from the scored adaptive test and is used by admissions teams as supporting evidence of your writing ability.
Score Report
Within 2 daysYour overall score (10–160) is accompanied by four subscores: Literacy, Comprehension, Conversation, and Production, each also on a 10–160 scale. Institutions can see all four subscores, which gives them a detailed picture of your English skills across different modes.

Frequently Asked Questions
How much does the Duolingo English Test cost for Sri Lankan students?
The Duolingo English Test costs USD 65 per attempt (approximately LKR 20,000–22,000 at 2025 exchange rates). This is significantly cheaper than IELTS (approximately LKR 45,000–55,000) or PTE Academic (approximately LKR 35,000–40,000). You pay online by credit or debit card, and the fee includes unlimited free score sends to universities in your first 48 hours after results are released.
Is the Duolingo English Test accepted by universities in the UK?
Acceptance in the UK is limited but growing. As of 2025, a number of UK universities and pathway providers accept DET, but the majority of UK Russell Group and most traditional universities still require IELTS Academic or PTE Academic. Always check the specific admissions page of your target institution. If you are applying to UK universities, IELTS Academic remains the safest choice unless you have confirmed DET acceptance in writing from the admissions office.
How long does it take to get Duolingo English Test results?
Duolingo typically releases results within 2 business days of completing the test. You will receive an email notification when your results are available in your dashboard. This is considerably faster than IELTS (3–13 days depending on paper-based or computer-based) and is one of the main advantages of DET for students facing tight application deadlines.
What equipment do I need to take the Duolingo English Test at home in Sri Lanka?
You need a computer or laptop (not a mobile phone or tablet) running Windows 10/11 or macOS, a working front-facing webcam, a microphone, a stable internet connection (minimum 3 Mbps upload speed), and a quiet, private room where you will not be interrupted. The test uses AI proctoring — it monitors your screen, face, and audio throughout. Slow or unstable internet is the most common reason for test disruptions in Sri Lanka, so test your connection speed beforehand.
What is a good Duolingo English Test score for university admission?
DET scores range from 10 to 160. A score of 105–114 is roughly equivalent to IELTS 6.0–6.5 and meets most undergraduate admission requirements. A score of 115–125 is roughly equivalent to IELTS 6.5–7.0, which meets most postgraduate requirements. For highly competitive programmes, a score of 125–135+ may be expected. Always confirm the exact score requirement with your target institution rather than relying on equivalency tables.
Can I retake the Duolingo English Test if I am not happy with my score?
Yes. There is no mandatory waiting period between attempts — you can retake as soon as 14 days after your previous test. You can take the test up to twice in any 30-day period. Your score is valid for two years. You choose which scores to share with institutions, so you can retake and only share your best result.
