What is the Duolingo English Test (DET)?

The Duolingo English Test (DET) is a unique evaluation created to measure the level of English fluency in individuals who learn English as their second language. The DET uses adaptive technology, meaning the level of questions will change depending upon how well you answer previous questions throughout the test. 

For example, if you answer few questions correctly after about 15 or 20 minutes of testing, your next set of questions will be more difficult; whereas if you answered correctly more than 80% of your previous questions then your next set of questions will be easier. 

• Length of the Test: Approx. 1 hour
• Test Format: Online, on-demand 
• Test components: Reading, Listening, Speaking, Writing

Students researching studying abroad in Sri Lanka often begin to look at traditional English tests i.e. IELTS or PTE as an option, but the DET is an appealing substitute due to its flexibility and cost savings. At PTE Magic we recommend using the DET for fast results with a mobile application and check with each program to ensure the program of choice accepts DET other than traditional tests like IELTS.

Duolingo English Test Fee in Sri Lanka (2026 Update)

Cost is a major factor for Sri Lankan applicants. As of early 2026, the DET fee Sri Lanka remains significantly more affordable than its competitors.

• Single Test Fee: USD 70 (Approx. LKR 21,000 – 22,500 depending on the exchange rate).
• Two-Test Bundle: USD 118 (Approx. USD 59 per test). Students are encouraged to take advantage of the two-test bundle to allow them to receive two attempts and submit their highest score.
• Fast Track Results (Optional): An additional USD 40 to receive scores within 12 hours.

Note: There are no “late registration fees” or “rescheduling fees” because the test is taken on-demand. You simply buy the credit and take the test when you are ready.

Is the Duolingo English Test (DET) Accepted for Sri Lanka Applicants?

The short answer is Yes, but the level of acceptance depends on your destination and the type of application.

Acceptance for university admissions

Quickly growing recognition of the Duolingo English Test (DET) is on the rise, with over 5,000 institutions worldwide currently using the DET as an acceptance for admissions. This includes:

USA: Many well-known Institutions are now accepting DET, with a large number of Universities from many different levels of university working together to increase their acceptance criteria.

UK: Many universities in the UK now accept the DET for admissions but some applicants may still need the IELTS to qualify for certain visa reasons such as the SELT.

Canada: Many colleges and universities across Canada now accept the DET as an acceptable form of admission.

Australia and Ireland: There is an increasing number of universities in Australia and Ireland now accepting the DET for both undergraduate and postgraduate courses.

Acceptance for visas and migration routes

The rules around legal visa processing for 2025-2026 differ greatly from each country to country. Therefore, it is very important to note that “accepted by a university” and “accepted by immigration” are two different things.

• USA: Near universally accepted for University admissions (95% of the top 100) and widely accepted for student (F-1) visas.
• Canada: It is accepted by about 90% of the top Universities for admission; however, it is not accepted for the Student Direct Stream (SDS) expedited process for immigration but is a valid option for the regular study permit application.
• Australia: Generally, this is not accepted for the visa application (subclass 500), and the Department of Home Affairs also requires IELTS, PTE, or TOEFL for student visa applications; however, this is accepted by many Australian Universities for application for admission and obtaining an Offer Letter.
• UK: Many Universities accept this for admission; however, this may not be accepted for all visa applications, especially for courses below a degree level and requiring Secure English Language Tests (SELT).
• Ireland: 15 out of 18 Universities recognize this English language accreditation and also for student visa applications.

DET Acceptance Summary Table

Country	Academic Acceptance	Visa/Migration Acceptance
USA	Very High (98% of top 100)	Accepted for F-1 Student Visas
Canada	Very High (90% of top universities)	Accepted for regular study permits
Ireland	High (15/18 Universities)	Accepted for student visas
UK	Moderate to High (80+ universities)	Accepted by many, but not all (check for SELT)
Australia	Moderate (Group of 8/others)	No (Not for Student Visa 500)

Duolingo English Test (DET) Requirements in Sri Lanka (Home Test Rules)

The Duolingo test is administered at home; therefore, strict security protocols are implemented to reduce or eliminate possible cheating. You will see “uncertified” results for the entire period you received them if you do not follow the guidelines below. 

Identification requirements

For taking the test, you must have a valid, original, government issued photo identification. International Passport is the most highly recommended ID to have as an original ID for Sri Lankan students because it is recognized by the DET AI-verification system. As part of the onboarding process, you will be asked to hold your physical ID up to your webcam. 

The name used during registration must match your ID exactly. (Even a small spelling difference or your nickname can cause you to have your score rejected). Photocopies or digital images of your ID on a phone cannot be accepted; you must have your physical ID.

Equipment and room setup checklist

You need a computer that has a working front-facing camera, working microphone, and internal or external speakers. You cannot use headphones/earbuds when testing to maintain academic integrity. A new “Secondary Camera” requirement often requires you to use your smartphone as a secondary camera to monitor the area around you while testing. 

You must have a private, quiet area with a closed door for testing. You must clear all items from the top of your desk, except your computer and ID. Do not sit in front of a window but rather sit in front of a desk with the sun shining through the window behind you; otherwise, your face will be unrecognizable to the proctors and your test invalidated.

Test Format, Timing, and Scoring

Unlike the traditional paper or fixed format testing (such as IELTS or TOEFL), the DET uses a more sophisticated adaptive algorithm that adjusts the difficulty of the items you are given based on how you answered previous questions; therefore, the better you do, the tougher the questions become.

Test Structure

Introduction & Onboarding (approximately 5 minutes): This portion of the test contains the introductory rules for taking the test, identification verification, connection to your camera/microphone. The onboarding/introduction section is not graded.

Adaptive Testing (approximately 45 minutes): The adaptive test consists of 13 or more different types of fast-paced mixed question types for you to answer. The level of difficulty will increase if you answer correctly and decrease if you answer incorrectly. This adaptive test will help to accurately assess your proficiency level.

Writing & Speaking Sample (approximately 10 minutes): The writing and speaking sections will consist of responding to open-ended prompts. Your responses will not affect your test score; they will be provided to the institution to which you sent your results as part of your test results, but will not be included in your numeric score calculation.

Types of Questions

• Read and Select: Picking out the real words that are part of a mixture of other words which are made-up.
• Listen and Type (Dictation): You’ll hear the same sentence read once, and you must then type it out exactly as it was read.
• Read and Complete: You will then be given a written passage to fill in a few missing letters.
• Read Aloud: You’ll be required to read a sentence back into a microphone.
• Interactive Reading/Listening: Exercises that involve having conversations or context in order to show you can follow along with the information you’ve heard.
• Speaking/Writing Sample: Activities such as explaining a picture to someone or speaking/writing for an allotted length of time about your subject.

Scoring and Results Delivery

Score Range: Results are reported in a range of 10 to 160 in 5-point increments.

Detailed Reporting: You will be provided with an Overall Score and Subscores for Literacy, Comprehension, Conversation, and Production. Starting in July 2024, you will be able to see individual scores for the 4 skills: Reading, Writing, Listening, and Speaking. 

Retakes and Results Timeline

As part of the planning process for university applications deadlines in Sri Lanka, it is essential to recognize how many times you can sit for an exam and how long after taking the original exam, you will receive your exam results.

Results Timeline

Standard Results: Generally, you’ll receive your certified score within 48 hours after taking the exam.

Faster Results (Optional): If you’re under pressure and need your results sooner, you can purchase the “Faster Results” add-on for a fee of $39 to receive your results within 12 hours after taking the exam.

Notification: You’ll receive a formal notification via email when your test results are available and at that time, you can check your test score at englishtest.duolingo.com.

Invalid Results & Appeal Process: When you have taken a test which was not certified because of some rule violation, an email will be sent to you. You may appeal the certification decision within 72 hours of receiving your notice to do so.

Retake Policies and Rules

Attempt Limits: You may buy up to three (3) tests per 30-day period.

Test Credits: For each test you order, you’ll get 1 test credit, which lets you have a maximum of 3 attempts to start and finish an exam (this helps if there’s a sudden electrical outage or other technical issue while you are trying to get into/establish an exam).

Waiting Period: There is no official waiting period between tests; however, you may not begin an exam again until your prior test has been officially certified or denied.

Uncertified Results: If your test results are not certified due to a minor technical difficulty or an unintentional violation of the rules, it generally will not count against your three-test-per-month limit.

Expiration: Once you buy a test credit, you have 21 days to finish taking the test before that credit expires.

How to Prepare for DET in Sri Lanka (Practical Study Plan)

You can earn a very high score within one week if you have a systematic approach to study. This plan correspond to the way DET exams adapt to each student’s performance level:

Day	Focus Area	Activity
Day 1	Familiarization	Take the free 15-minute practice test on the official website.
Day 2	Vocabulary & Spelling	Practice the “Read and Select” and “Read and Complete” tasks.
Day 3	Listening Skills	Focus on “Listen and Type” – accuracy in punctuation is key!
Day 4	Image Description	Practice describing complex images in under 60 seconds.
Day 5	Writing Tasks	Focus on the 50-word minimum writing prompts. Use diverse grammar.
Day 6	Full Mock Test	Use the PTE Magic platform logic: practice under timed conditions.
Day 7	Final Review	Review common mistakes and ensure your room setup is ready.

Common Reasons Scores Get Delayed or Not Certified (And How to Avoid It)

Many Sri Lankan students have “uncertified” test results due to minor mistakes the AI flagged as questionable. Below are three common causes of delays or rejections:

• Eye Movement & Focus Violation: Consistently looking away from the screen for too long is the main cause of non-certification. To avoid this, keep your eyes on the screen or the prompt you are answering; if you need to think, focus your gaze straight ahead, not up or down.
• Environmental & Setup Issues: Your entire face, all your eyes, and both of your ears must be visible the entire time you are testing; any external intrusion will invalidate the testing session. To avoid problems with this, put your hair back, light your testing area with a bright desk lamp to eliminate shadows, and put a “Do Not Disturb” sign on your door so family members cannot come in while you are testing.
• Integrity/Behavior Flags: AI flags response rehearsed beforehand or viewed with the help of external tools (like notes or prohibited software). To eliminate this issue, speak as naturally as possible (like you are having a real conversation), clear your computer desk of all electronic devices and paper, and disable all background apps (like Grammarly or other extensions) before you start testing.
• Issues with Connection and Technical Problems: The internet connection when taking an exam needs to be stable; if not, it may cause you to fail the test. To avoid problems with your connection, use an Ethernet cable whenever possible instead of a wireless connection, do a speed test prior to taking the exam, and make sure you have the latest version of the official DET desktop application installed on your computer.
• Account Issues and Identification Problems: Unsatisfactory captures of your ID or having multiple accounts are very concerning indicators. If you would like to avoid this, please take the test in an area with natural light (side-light only) so you can prevent glare off of the ID, create only one main email address that you will use for all your testing, and ensure that your ID does not have an expiration date on it.
