Duolingo English Test: Is It Accepted and How Indian Students Should Prepare

The Rise of the Duolingo English Test

The Duolingo English Test (DET) went from a niche alternative to a mainstream admissions test almost overnight. When the pandemic shut down IELTS and TOEFL test centres globally in 2020, thousands of universities added DET to their list of accepted English proficiency tests. What started as an emergency measure has become a permanent fixture at over 5,000 institutions worldwide, and Indian students are increasingly choosing it as their primary English proficiency test.

The appeal is obvious. The DET costs USD 65 (approximately INR 5,400) -- roughly one-third the cost of IELTS or TOEFL. You take it from home on your own computer. It takes under an hour. Results arrive within 48 hours. For Indian students managing tight budgets and tighter deadlines, these advantages are compelling.

But the critical question remains: is it accepted where you want to go, and does it carry the same weight as IELTS or TOEFL in the eyes of admissions committees? The answer is nuanced, and this guide covers everything Indian students need to know.

DET Score Scale and University Requirements

The Duolingo English Test is scored on a scale of 10-160. Here are the score equivalences and common university requirements:

Score Equivalences

• DET 100 = IELTS 6.0 = TOEFL 72
• DET 110 = IELTS 6.5 = TOEFL 83
• DET 120 = IELTS 7.0 = TOEFL 95
• DET 130 = IELTS 7.5 = TOEFL 107
• DET 140 = IELTS 8.0 = TOEFL 114

What Top Universities Require

• Top 20 US universities (those that accept DET): Minimum 120-130. Columbia requires 120, Yale requires 120, MIT does not accept DET.
• Top 20-50 US universities: Minimum 105-120. University of Michigan requires 115, NYU requires 120.
• Canadian universities: Most require 115-125. University of Toronto requires 120.
• UK universities: Limited acceptance. University College London requires 125. Most Russell Group universities do not accept DET.
• Australian universities: Growing acceptance. Most require 100-110.

Where DET Is and Is Not Accepted

This is the most important section for Indian students. DET acceptance varies significantly by country, university, and even programme within the same university.

Strong Acceptance

• United States: Over 3,000 US institutions accept DET, including many top universities: Columbia, Yale, Duke, Johns Hopkins, NYU, University of Chicago, Northwestern, and most state universities. However, some top programmes -- particularly at MIT, Stanford, and certain graduate programmes -- do not accept DET.
• Canada: Growing acceptance at major universities including University of Toronto, UBC, McGill, University of Waterloo, and McMaster. Immigration authorities (IRCC) do not accept DET for PR or work permits.

Limited or No Acceptance

• United Kingdom: Most Russell Group universities do not accept DET. Notable exceptions include UCL and some programmes at Queen Mary and Exeter. UKVI does not accept DET for visa purposes. If you are applying to UK universities, IELTS remains the safer choice.
• Australia: Acceptance is growing but not universal. Group of Eight universities have mixed policies -- some accept DET for admissions but require IELTS or PTE for visa purposes.
• Germany and Europe: Limited acceptance. Most German universities and European programmes prefer IELTS, TOEFL, or Cambridge English tests.

Critical warning: Always verify DET acceptance with your specific programme, not just the university. A university may accept DET for its undergraduate programmes but not for its MBA or medical school. Check the admissions page of each programme you are applying to.

Understanding the DET Format

The Duolingo English Test is adaptive -- questions get harder or easier based on your performance. The test takes approximately 45 minutes and consists of two main parts:

Adaptive Test (Graded, 45 minutes)

• Read and Complete: Fill in missing letters in words within sentences. Tests vocabulary and spelling.
• Read and Select: Identify real English words from a list that includes fake words. Tests vocabulary breadth.
• Listen and Type: Listen to a word or sentence and type it. Tests listening and spelling.
• Read Aloud: Read a sentence aloud. Tests pronunciation and fluency.
• Write About the Photo: Describe an image in writing (minimum 1 sentence, ideally 3-5 sentences).
• Speak About the Photo: Describe an image verbally (30-90 seconds).
• Read Then Write: Read a prompt and write a response (minimum 50 words).
• Listen Then Speak: Listen to a question and respond verbally (30-90 seconds).
• Interactive Reading: Complete cloze passages, highlight key sentences, identify titles.
• Interactive Listening: Record missing words from an audio clip, summarise a conversation.

Video Interview and Writing Sample (Ungraded)

After the graded section, you complete a 10-minute ungraded portion: two speaking prompts (recorded on video) and one writing prompt. These responses are not scored but are sent to the universities you designate. Admissions officers use these to get a qualitative sense of your communication ability.

The ungraded section is important even though it does not affect your score. A strong video interview can reinforce a good score; a weak one can raise doubts even with a high score.

DET Subscores

Since July 2023, DET reports four subscores in addition to the overall score:

• Literacy: Reading and writing ability
• Comprehension: Reading and listening ability
• Conversation: Listening and speaking ability
• Production: Writing and speaking ability

Each subscore is on a 10-160 scale. Some universities set minimum subscores in addition to overall score requirements. For example, a university might require an overall 120 with no subscore below 100.

Preparation Strategy for Indian Students

Target Scores by Destination

• Top US universities: Target 125-135
• Mid-range US universities: Target 110-120
• Canadian universities: Target 120-125
• Australian universities: Target 105-115

Section-by-Section Tips

Read and Complete / Read and Select:

• These sections reward broad vocabulary. Unlike IELTS or TOEFL, DET tests whether you can recognise English words -- including uncommon ones. Build vocabulary through extensive reading. Use apps like Vocabulary.com or Memrise for daily practice.
• For Read and Complete, the strategy is to read the entire sentence first, understand the context, and then fill in the missing letters. Do not guess individual words -- use the sentence context to guide you.

Listen and Type:

• Practice dictation daily. Use TED Talks, podcasts, or YouTube videos. Play a sentence, pause, type it out, then check against the transcript. Start with slower speakers and gradually increase speed.
• Common mistakes for Indian students: confusing "there/their/they're," "its/it's," and other homophones. Practice these specifically.

Read Aloud:

• Pronunciation matters more on DET than on IELTS. The AI scoring system evaluates clarity, fluency, and natural stress patterns. Practice reading English text aloud for 15 minutes daily.
• Focus on stress patterns: English stress falls on different syllables than Hindi or other Indian languages. "DEvelopment" not "developMENT." "PHOtograph" not "photoGRAPH." Record yourself and listen for unnatural stress patterns.

Write About the Photo / Read Then Write:

• Write in clear, simple sentences. DET's AI scoring rewards grammatical accuracy and relevant content over sophisticated vocabulary. "The image shows a busy street market with vendors selling vegetables and fruits. Several customers are examining the produce while a child plays nearby." This is better than flowery, complex writing.
• Aim for 3-5 sentences for photo descriptions and 100-150 words for reading-based responses. Cover the key elements systematically rather than trying to be creative.

Speak About the Photo / Listen Then Speak:

• Structure your spoken response: "This image shows... I can see... It appears to be... Overall..." Having a simple framework prevents rambling and ensures you cover the key points within the time limit.
• Speak at a moderate pace. The AI penalises both rushed speech and long pauses. If you make a mistake, do not go back and correct it -- continue speaking naturally.

Preparation Timeline

4-6 Week Plan for Indian Students

DET requires less preparation time than IELTS or TOEFL because the format is less complex. However, it still requires dedicated practice.

• Week 1: Take the free DET practice test on Duolingo's website. Identify your weakest areas. Begin daily reading (30 minutes) and listening (30 minutes).
• Weeks 2-3: Focus on your weakest section types. Practice Read and Complete questions, dictation exercises, and read-aloud exercises daily. Write 2-3 photo descriptions per day.
• Weeks 4-5: Take another practice test. Identify remaining weaknesses. Practice the speaking tasks with a timer. Work on pronunciation.
• Week 6: Final practice test. Light review. Ensure your test environment meets DET requirements (quiet room, stable internet, working camera and microphone).

Test Day Requirements

Since DET is taken from home, the technical and environmental requirements are strict:

• Computer: Desktop or laptop with a front-facing camera and microphone. Tablets and phones are not allowed.
• Browser: Latest version of Chrome, Firefox, Edge, or Opera. The test runs in the browser -- no separate app needed.
• Internet: Stable broadband connection. The test streams audio and video continuously.
• Environment: You must be alone in a quiet room with the door closed. No headphones or earphones allowed. No external materials, notes, or second screens.
• ID: Valid passport or national ID card. You take a photo of it during the test setup.
• Rules: You cannot look away from the screen for extended periods. The AI proctoring system monitors eye movements and will flag suspicious behaviour. Tests flagged for integrity issues are not certified.

Important for Indian students: Ensure your internet connection is reliable. DET will not certify results if the connection drops during the test. If your home internet is unreliable, consider going to a friend's place or a co-working space with stable Wi-Fi. Also, be aware that background noise (traffic, construction, family members) can trigger integrity flags.

Is DET Taken Seriously by Admissions Committees?

This is the question every Indian student really wants answered. The honest answer: it depends on the university and the programme.

At universities that have accepted DET for years (Columbia, Yale, Duke, most Canadian universities), admissions committees treat DET scores as equivalent to IELTS and TOEFL scores. They have built internal conversion tables and have enough data to interpret DET scores confidently.

At universities that added DET recently or that still list it alongside a "preferred" test (usually IELTS or TOEFL), there may be a subtle bias. Some admissions officers have privately noted that they view DET as a "softer" test, particularly for competitive programmes. This is not universally true, but it is worth considering for highly competitive applications.

My recommendation: if your target programme explicitly lists DET as accepted (not just "may be considered"), use it confidently. If the programme lists DET as an alternative with IELTS or TOEFL as preferred, consider whether the cost and convenience savings are worth the potential perception gap. For most applications, they are.

DET vs IELTS vs TOEFL: Quick Decision Guide for Indian Students

• Budget-conscious with tight deadlines: DET
• Applying to UK universities: IELTS (mandatory for UKVI)
• Applying exclusively to US universities: TOEFL or DET (check programme acceptance)
• Applying to Australian universities for PR pathway: IELTS or PTE (DET not accepted by immigration)
• Applying to Canadian universities: DET, IELTS, or TOEFL (all widely accepted for admissions; DET not accepted for PR)
• Applying to European universities: IELTS or TOEFL (DET acceptance is limited)

Final Thoughts

The Duolingo English Test has earned its place as a legitimate alternative to IELTS and TOEFL for many Indian students. Its lower cost, home-based convenience, and rapid results make it particularly attractive. However, it is not a universal replacement. Indian students must verify acceptance at their specific target programmes, prepare for the AI-proctored format, and ensure their home testing environment meets the strict requirements. Used strategically, DET can save Indian students significant money and time without compromising their application strength.
