If you had to pick just two, IELTS and TOEFL are the ones you'll run into most often. IELTS tends to be the go-to across the UK, Australia, and Canada, while TOEFL is what most U.S. universities expect. PTE Academic is worth a look if you want your score back fast and don't love the idea of being judged by a human examiner — it's accepted in pretty much the same countries as IELTS. And if you're watching your budget or just can't get to a test center, the Duolingo English Test lets you do the whole thing from your laptop at home, and it's now on the accepted list at more than 4,000 institutions.
Put simply, it's how a university checks that you can actually function in English before you show up — following a lecture, writing a coherent essay, holding your own in a seminar discussion. Nobody enjoys taking these tests, but admissions offices rely on them because a strong application essay doesn't tell them whether you can keep up in a 9am lecture hall. On top of admissions, you'll usually need the same score for your student visa and often for scholarship applications too, so it's rarely a one-off requirement.
Honestly, it comes down mostly to where you're applying:
| Test | Skills Tested | Format | Score Range | Test Duration | Best Accepted In | Validity |
| IELTS | Listening, Reading, Writing, Speaking | Paper or computer; in-person speaking | 1.0–9.0 | ~2 hrs 45 min | UK, Australia, Canada, Europe, Ireland | 2 years |
| TOEFL iBT | Listening, Reading, Writing, Speaking | Fully internet-based | 0–120 | ~3 hrs | USA, Europe (English-taught programs) | 2 years |
| PTE Academic | Listening, Reading, Writing, Speaking | Fully computer-based, AI-scored | 10–90 | ~2 hrs | Australia, UK, New Zealand, Ireland | 2 years |
| Duolingo English Test | Adaptive four skills + video interview | Online, at-home | 10–160 | ~1 hr | 4,000+ institutions globally, incl. Western Europe | 2 years |
IELTS is the test most people have at least heard of, and for good reason — over 11,000 institutions accept it, especially across the UK, Australia, Canada, and much of mainland Europe. What sets it apart is the speaking section: you're sitting across from a real examiner, having an actual conversation, rather than talking into a microphone and hoping for the best. If you're someone who freezes up talking to a screen but does fine in person, this matters more than you'd think.
TOEFL iBT is the one most U.S. universities expect by default, and it's also picking up traction across Canada and Europe — particularly for English-taught programs in Germany, the Netherlands, and Scandinavia. It's entirely internet-based, no paper option at all, and leans academic in style: think lecture-style listening clips and dense reading passages that feel a lot like actual coursework. If you type faster than you write and you're aiming for American schools, this is probably your test.
PTE Academic is the one to consider if speed matters to you. Scoring is done entirely by AI — no human raters, no waiting around wondering how an examiner interpreted your accent. That also means you'll usually get your results back within 48 hours, which can be a real advantage if application deadlines are creeping up. It's well established in Australia, the UK, New Zealand, and Ireland, and it's steadily gaining acceptance across mainland Europe too.
The Duolingo English Test is the outlier here, in a good way. There's no test center — you just do it at home on your webcam, and it usually takes about an hour. The difficulty adjusts as you go, and it wraps up with a short video interview. It's also considerably cheaper than the other three. More than 4,000 institutions now accept it, and that number keeps climbing, so if convenience and cost are your main concerns, this is worth serious consideration.
Is IELTS or TOEFL better for university admission? Neither one is objectively better — it really depends on where you're applying. TOEFL is the default for U.S. schools; IELTS tends to be the default across the UK, Australia, and Canada. When in doubt, check what your specific university actually asks for.
Is the Duolingo English Test accepted by real universities? Yes, it is — officially accepted by more than 4,000 universities and colleges worldwide at this point. That said, acceptance still varies by institution, so it's worth confirming on the university's own admissions page before you commit to it.
How long are English proficiency test scores valid? All four — IELTS, TOEFL, PTE Academic, and Duolingo — stay valid for 2 years from your test date.
Which English test is the cheapest? Duolingo, by a fair margin. PTE Academic comes in next, with IELTS and TOEFL usually costing more.
Which English test gives results the fastest? Duolingo and PTE Academic both tend to return results within 48 hours, since neither relies much on manual scoring.
Which English test is best for European universities? IELTS has the broadest recognition across Europe overall, but TOEFL isn't far behind, especially for English-taught bachelor's and master's programs in places like Germany, the Netherlands, and Scandinavia. Ireland follows UK norms, so IELTS and PTE both work there. As always, double-check with the specific university, since requirements can shift from program to program even within the same country.

There's no single "best" test here — just the one that fits where you're headed, how you test, and what your budget and timeline look like. Nail down your shortlist of universities first, confirm exactly what they'll take, and then pick the test that plays to your strengths rather than just going with whatever's most talked about online.
