IELTS vs TOEFL vs Duolingo: Which English Test Should You Take?
An honest 2026 comparison for Indian students — cost, format and scores, which test each country accepts (for admission and the visa), and the one trap that costs students a whole test fee.
The Short Version
- There is no “best” test — only the right test for your target country and your strengths.
- IELTS is the safest, most widely accepted choice (and often required for the UK visa). TOEFL is the US favourite. Duolingo is cheapest and fastest — strongest for the USA.
- The trap that costs students a whole fee: a test accepted for admission may not be accepted for the visa. Duolingo, for example, is not valid for UK or Australian student visas — even where universities accept it.
- Always confirm both the university’s required score and the visa authority’s accepted tests before you book.
- Many universities now let you study without IELTS — via a medium-of-instruction letter or an alternative test.

Why the English Test Matters (and the Visa Trap)
For almost every English-taught programme abroad, an English proficiency test is a gatekeeper — and for Indian students, it’s one of the few requirements you fully control. Score well and you clear a hard filter; miss it and even a strong application stalls.
But here’s the mistake that quietly costs students the most: they check whether their university accepts a test, book it, and only later discover the visa authority doesn’t. Admission acceptance and visa acceptance are two separate lists. A UK university might accept Duolingo for admission, but the UK Home Office does not accept it for the student visa — so you’d need to sit an approved test anyway. Always clear both checks before you pay.
The Three Tests at a Glance
The headline differences that actually shape your choice — cost, format, speed and where each shines. (PTE Academic is a strong fourth option, especially for Australia.)
| IELTS Academic | TOEFL iBT | Duolingo (DET) | |
|---|---|---|---|
| Cost (approx) | ~₹16,000–17,000 | ~₹16,000–17,000 | ~₹2,000–2,500 |
| Format | Centre (or online); human-scored speaking | Centre or online, proctored | At home, online, adaptive |
| Results | ~3–5 days (computer) | ~4–8 days | ~2 days |
| Score | Bands 0–9 | 0–120 | 10–160 |
| Validity | 2 years | 2 years | 2 years |
| Strongest for | UK, Canada, Australia; any target if unsure | USA & North America | USA; budget / tight timeline |
Which Test Works in Which Country
This is the table to bookmark. For each destination, check what’s accepted for admission and, separately, for the student visa — then pick a test that clears both.
| Country | Admission | Student visa | Safest pick |
|---|---|---|---|
| USA | All widely accepted; Duolingo by thousands of universities | University-driven (F-1); if the uni accepts it, it generally works | TOEFL or Duolingo |
| UK | IELTS preferred; TOEFL at many; Duolingo at a few | IELTS (UKVI) or PTE Academic (UKVI). Duolingo not valid. | IELTS |
| Canada | IELTS, TOEFL, PTE and Duolingo (accepted by most top universities) | Study permit needs IELTS / PTE / TOEFL / CELPIP. Duolingo not on the IRCC list. | IELTS |
| Australia | IELTS, PTE, TOEFL; Duolingo at ~40–50 institutions | IELTS / PTE / TOEFL / Cambridge / OET. Duolingo not accepted for the visa. | IELTS or PTE |
| Europe / Others | IELTS and TOEFL widely accepted; Duolingo growing | Usually IELTS or TOEFL; varies by country | IELTS or TOEFL |
Which Test Should You Take?
Start from your target country, not from which test looks “easiest.” This flowchart gets you to the right answer in seconds.
Score Equivalence (Approximate)
Universities set their requirement in one test’s units; this rough map helps you translate a target across tests. Treat it as a guide only — always use the exact score your university states.
| IELTS band | TOEFL iBT | Duolingo (DET) | Reads as |
|---|---|---|---|
| 6.0 | 60–78 | 95–100 | Many foundation / some UG |
| 6.5 | 79–93 | 105–115 | Common UG / PG minimum |
| 7.0 | 94–101 | 120–125 | Competitive programmes |
| 7.5 | 102–109 | 130–135 | Top universities / some scholarships |
Approximate concordances — the Duolingo-to-IELTS relationship in particular is only moderate. Always use your university’s own stated requirement.
Test Trends in 2026
- The duopoly has cracked. The old TOEFL/IELTS pairing has been disrupted by PTE Academic and the Duolingo English Test — more choice, more confusion.
- Duolingo’s rise. Its low cost, at-home format and ~48-hour results have made it a genuine option, especially for US applications.
- Shorter tests. Both IELTS and TOEFL now run shorter than their older versions.
- Admission vs visa is the new fault line. As Duolingo acceptance for admission outpaces its acceptance for visas, the gap between the two lists is where students get caught.
- “Without IELTS” is growing. More universities waive the test for English-medium students or accept a medium-of-instruction letter.
How Indian Students Should Prepare
Indian schooling tends to build strong reading and grammar, but classroom English rarely rehearses timed speaking to a screen or fast academic listening across accents. Prepare accordingly.
- Take a diagnostic first. Sit a free practice version of your shortlisted test before committing. Your real strengths (and the format that suits them) decide the test as much as the country does.
- Start early, with a buffer. Plan your test so there’s room for one retake before your deadline — scrambling for a last-minute score is the most avoidable mistake.
- Target your weak section. For most Indian students that’s speaking fluency and listening under time pressure, not reading. Practise speaking aloud and to a recorder daily.
- Respect Duolingo’s format. It’s at-home and adaptive — it gets harder as you do well, and tests typing, quick thinking and speaking to a camera. Easy to book is not the same as easy to ace.
- Book the score that clears both. Aim comfortably above your university’s minimum, and confirm the test satisfies your visa route too.
Studying Without IELTS
You often don’t need IELTS at all. A growing number of universities waive the English test if your prior education was in English, or accept a medium-of-instruction (MOI) letter from your school or college. Others accept an alternative test — TOEFL, PTE or Duolingo — that may suit you better.
The catch is the same one running through this whole guide: a waiver for admission may not satisfy the visa. Confirm both before you assume you can skip the test entirely.
How ImpactGrad Helps
The English test is small in the scheme of an application — but a wrong call here costs money and, worse, time. We help our students make the call once and correctly: matching the test to their target countries and their strengths, confirming acceptance for both admission and visa, setting a target score with headroom, and building it into a realistic timeline so it never becomes a last-minute scramble. It’s one of the many small, high-leverage decisions that a good mentor gets right so you don’t have to redo it. See how we work.
Common Mistakes
- Checking admission, forgetting the visa. The single most expensive error — a valid admission test that your visa route won’t accept.
- Picking the “easiest” test. Easy to book (Duolingo) is not easy to score, and “easiest” is worthless if your target doesn’t accept it.
- Booking too late. No buffer for a retake turns a fixable low score into a missed deadline.
- Aiming exactly at the minimum. One weak section on the day and you’re under the bar. Build in headroom.
- Assuming score equivalence is exact. Concordances are approximate — especially Duolingo to IELTS. Use the university’s stated figure.
Frequently Asked Questions
Which English test is best for Indian students?
There’s no single best test — it depends on your target country and strengths. IELTS is the safest, most widely accepted choice and often required for the UK visa; TOEFL is preferred in the US; Duolingo is the cheapest and fastest and works well for the USA. If you’re unsure where you’ll apply, IELTS keeps the most doors open.
Is Duolingo accepted for study abroad?
Increasingly, yes — thousands of universities accept the Duolingo English Test for admission, especially in the USA and Canada. But acceptance for admission is not the same as acceptance for the visa: Duolingo is not valid for UK or Australian student visas, and not on Canada’s study-permit list, even where universities accept it. Always confirm both.
IELTS or TOEFL for the USA?
Both are accepted across US universities. TOEFL has the strongest brand recognition with US admissions and is designed for the North American context, so it’s the natural default — but IELTS is accepted everywhere too. Choose based on which format suits your strengths after a diagnostic.
Which English test do I need for a UK student visa?
For the UK student visa you need an approved Secure English Language Test — typically IELTS for UKVI or PTE Academic UKVI. Duolingo is not accepted for UK visa purposes, even if a university accepts it for admission, so IELTS is the safest choice for the UK.
Can I study abroad without IELTS?
Often, yes. Many universities waive the English test if you studied in English or accept a medium-of-instruction letter, and others accept an alternative test such as TOEFL, PTE or Duolingo. Confirm the specific programme’s policy — and check the visa requirement separately.
Which is the cheapest English test?
The Duolingo English Test is by far the cheapest — roughly a fifth of the cost of IELTS or TOEFL — and gives results in about two days. It’s a strong option where accepted, but the low price is only worth it if your target university and visa route both accept it.
How long is an English test score valid?
IELTS, TOEFL and Duolingo scores are all valid for two years. Plan your test so a valid score covers your full application cycle, with a buffer for one retake if needed.
What score do I need?
It varies by university and course. A rough guide: IELTS 6.0–6.5 (TOEFL ~60–93, Duolingo ~95–115) covers many undergraduate and postgraduate minimums, while competitive programmes and scholarships often want 7.0+ (TOEFL 94+, Duolingo 120+). Always use the exact figure your university states and aim comfortably above it.
How should Indian students prepare?
Take a diagnostic to pick the test that suits your strengths, start early enough to allow a retake, and target your weakest section — usually speaking fluency and timed listening for Indian students, rather than reading. Practise speaking aloud daily, and treat Duolingo’s at-home format with the same seriousness as a centre-based test.
Not Sure Which Test Is Right for You?
The test is a small decision that’s expensive to get wrong. If you’re mapping out study abroad and want to make this call once — correctly, for both your universities and your visa — that’s exactly the kind of detail we get right for our students.
