Almost every Indian student heading abroad has to prove their English with a standardised test. The four names you will hear again and again are IELTS, PTE Academic, TOEFL iBT and the Duolingo English Test. They are not interchangeable, and picking the wrong one can cost you time, money and — occasionally — an admission or a visa.
This guide breaks down how the four tests actually differ, who each one suits, and how to choose based on your target country, your budget and your own strengths. The golden rule underneath everything: your test choice must satisfy both your university and your visa authority, and both change their rules, so always confirm on the official sources before you book.
The four tests at a glance
Each test measures the same four skills — Listening, Reading, Writing and Speaking — but the experience and scoring are very different.
- IELTS Academic — Scored in bands from 0 to 9. Run by the British Council, IDP and Cambridge. Available on paper or computer, but the Speaking section is a live face-to-face interview with a human examiner. The most widely recognised test across the UK, Australia, Canada and Ireland.
- PTE Academic — Fully computer-based and AI-scored, from 10 to 90. Run by Pearson. Known for very fast results and a heavily integrated format (one task can test speaking and reading at once). Strong acceptance in Australia, New Zealand and the UK.
- TOEFL iBT — Internet-based, scored 0 to 120. Run by ETS. Historically the default for the United States, and comfortable for students who prefer typing and an academic, lecture-style register.
- Duolingo English Test (DET) — Taken online from home in about an hour, scored 10 to 160. The cheapest and fastest option, adaptive in difficulty. Accepted by a large and growing list of universities, but acceptance for visa purposes is far more limited.
Format and scoring: where they really diverge
The format differences matter more than the score scales, because they favour different kinds of test-takers.
Speaking
IELTS is the only one of the four with a human examiner conversation. If you are confident face-to-face and freeze at a microphone, IELTS may play to your strength. PTE, TOEFL and Duolingo all record you speaking to a computer and score you with AI, which rewards clear, steady, well-paced English over conversational charm.
Structure and speed
PTE's integrated tasks mean strong performance in one skill can lift others. TOEFL leans academic and note-heavy. IELTS keeps the four sections cleanly separated. Duolingo mixes short, adaptive question types and is by far the shortest sitting.
Results timelines also differ a lot — Duolingo and PTE are typically the fastest, IELTS and TOEFL take a little longer. Because official turnaround times get updated, check the current figures on ielts.org, pearsonpte.com, ets.org/toefl and englishtest.duolingo.com before you plan around them.
Cost, and the honest truth about "which is easier"
In India, IELTS, PTE and TOEFL sit in a broadly similar fee range, while the Duolingo English Test is usually significantly cheaper. Fees change and vary by test centre, so confirm the current price on each official site rather than trusting a number you saw in a forum.
No test is genuinely "easier". Each one is easier for a particular person. The right question is not "which test is soft?" but "which format matches how I actually perform?"
A student who writes fast and thinks in structured paragraphs often prefers TOEFL. Someone who speaks clearly to a machine and works quickly tends to like PTE. A student who wants a real conversation and a paper option may prefer IELTS. Someone on a tight budget testing for an application that accepts it may start with Duolingo. Take a couple of free practice sets in different formats before you commit — our free Vibedu test-prep practice is a low-risk way to feel the difference before paying for a real slot.
The step everyone skips: acceptance and visas
This is where students lose money. A test being popular does not mean your university and your visa authority both accept it.
- For a UK visa, the Home Office only accepts specific approved Secure English Language Tests (SELT) for many visa routes — for example the UKVI versions of IELTS and PTE Academic. Duolingo is generally not accepted for UK visa purposes even where a university accepts it academically. Verify the current approved list on the official UK government SELT page.
- Australia and New Zealand accept IELTS, PTE and TOEFL widely, and have expanded acceptance of some newer tests for certain student visa streams — but the accepted list and minimum scores are set by the immigration department, not the university.
- The USA and Canada are largely university-driven for English requirements, and Duolingo is broadly accepted there — but individual programmes still set their own minimum scores and some do not accept it at all.
Two things are always true: acceptance is decided by the specific university programme and the visa authority, and both can update their rules. Never assume — check the admissions page of each course and the official immigration website for your country.
A simple way to choose
Work through this in order:
- List your shortlisted universities and courses. Note the exact tests and minimum scores each one accepts.
- Check your visa authority's approved list for your destination and route. Keep only the tests that satisfy both the university and the visa.
- Match the surviving options to your strengths — human vs AI speaking, paper vs screen, budget, and how fast you need results.
- Take a timed practice test in your top one or two formats before booking anything.
- Book early. Popular slots fill up, and you want room to retake if your first score falls short.
What to do next
Start with your university shortlist and their stated English requirements — that single document usually eliminates two of the four tests immediately. Then confirm the visa side on the official government source, try a free practice set in the format you're leaning towards, and book with enough buffer for a possible retake.
