IELTS vs Duolingo English Test (2026): Can It Replace IELTS?

Short answer: the Duolingo English Test can replace IELTS for many university applications, but not for most visas.

As of September 2026 it is not on the UK's Secure English Language Test (SELT) list, and it is not accepted for Canada's Express Entry or for Australian visas — IELTS is accepted for all three.

Duolingo costs US$70, takes about an hour at home, is scored 10–160 and returns results in about two days; IELTS is a roughly 2h 45m, four-skill centre exam scored in bands 1–9.

For a UK Student visa at degree level there is one exception: your university may assess your English itself, and some accept a Duolingo score for that. Your CAS will say so. Every other UK route in the table below needs a SELT such as IELTS for UKVI.

Because the Duolingo English Test is cheaper, shorter and can be taken from a bedroom on a laptop, it has become a genuinely popular alternative for university applicants — and a source of a lot of confusion about whether it will actually be accepted for a given goal.

This guide compares the two tests on the facts that matter: format and length, how the two scoring scales work, cost and convenience, and — most importantly — where each is and is not accepted.

Everything about fees, speed and acceptance changes over time and by country, so treat the figures here as "as of 2026" starting points and verify the current details on the official source before you book anything.

Can the Duolingo English Test replace IELTS?

It depends entirely on what the score is for. The table below is checked against the official government lists as of September 2026: the UK's approved SELT list (updated 21 September 2026), Canada's Express Entry language tests and Australia's Home Affairs list of approved English tests.

So the decision rule is short: if a visa is anywhere in your plan, the Duolingo score will not carry you through it — and in the UK one IELTS for UKVI Academic sitting can cover both a degree application and the visa.

If you only need admission, and every programme on your list accepts Duolingo, it can replace IELTS.

Format and length (structural facts)

IELTS is a four-skill exam with fixed, separately timed sections: Listening, Reading, Writing and Speaking, running to roughly 2 hours and 45 minutes in total. Listening and Reading each contain 40 questions worth one mark apiece, with no negative marking, and the Listening audio plays once only.

Speaking is a live, face-to-face interview with a trained human examiner.

Since paper-based IELTS ended in mid-2026 (the last paper test in most markets was 27 June 2026), you sit Listening, Reading and Writing on computer at an approved test centre, and the official structure is set out on the IELTS test format page.

There are two versions — Academic and General Training — and choosing the right one matters as much as choosing the test, as our guide to IELTS Academic vs General Training explains.

The Duolingo English Test takes a different shape. It is a single online adaptive session of roughly an hour, taken at home on your own computer with a webcam and microphone, available on demand rather than on fixed sitting dates.

"Adaptive" means the difficulty of each item adjusts to how you answered the previous ones, so the test can estimate your level in less time than a fixed-length paper.

Rather than four cleanly separated skill sections, it uses a series of short task types — reading and typing missing words, listening and transcribing, speaking into the microphone, writing short responses — many of which test more than one skill at once.

It also records a short video interview and open-ended writing sample that are sent, unscored, to institutions to review alongside the number.

Teaching example (an illustration written for this article, not a real test item from either exam): in IELTS Reading you might be given a statement and asked to decide True, False or Not Given by checking it against one place in the passage.

In an adaptive test, an equivalent early item might flash a sentence with several words blanked out and ask you to type them back under time pressure — and if you get it right, the next item is harder.

The point is not that one is easier, but that the two tests sample your English in structurally different ways.

Scoring scales compared

IELTS reports a score for each of the four skills on the nine-band scale, and your overall band is the average of the four rounded to the nearest half band.

The bands carry published descriptors — 9 is "expert user", 8 "very good", 7 "good", 6 "competent" and 5 "modest" — and map approximately to the CEFR (about 6.0 = B2, 7.0–8.0 = C1, 8.5–9.0 = C2).

Because bands move in half-steps, a single extra correct answer in Reading or Listening can lift a whole section, which is why our band score calculator is useful for seeing how section scores combine into an overall band.

The Duolingo English Test reports an overall score from 10 to 160 in five-point increments, along with subscores (commonly grouped as Literacy, Comprehension, Conversation and Production) on the same scale.

It is a more granular scale than the nine IELTS bands, so improvement can feel smoother, but institutions still publish hard cut-offs that turn that granularity back into thresholds.

Duolingo publishes its own official score-comparison chart mapping its scale to IELTS bands; the table below shows the broad, widely-cited neighbourhood, but treat every row as approximate and check the current official chart, because the two tests measure overlapping rather than identical skills.

Two cautions on that table. First, the ranges overlap and are approximate by nature — the only mapping that counts for your application is the one the receiving institution publishes.

Second, equivalences at the section or subscore level are looser than at the overall level, so if your target sets minimums on individual skills, check how the institution treats each one rather than assuming the overall conversion applies neatly across the board.

Cost and convenience (as of 2026)

Convenience is the Duolingo test's clearest advantage.

It is taken at home, on demand, without booking a centre or travelling, and as of September 2026 a single test costs US$70 (plus any local tax), with results within about 48 hours and free score-sending to as many institutions as you like.

IELTS is priced locally by the British Council and IDP and usually costs well over twice that — see IELTS fees by country for the current figure where you live. Confirm the Duolingo price at checkout on the official Duolingo English Test site before deciding.

IELTS trades some of that convenience for a centre-based experience. You book a specific date and location, and you sit under invigilation.

IELTS results typically arrive within 1 to 5 days now that the test is computer-delivered; the roughly 13-day wait for paper results ended with paper IELTS in 2026.

The at-home model removes travel and waiting but adds its own requirements: a quiet room, a stable internet connection, a working webcam and microphone, and adherence to strict remote-proctoring rules (no interruptions, eyes on screen, no notes).

For some candidates that is far easier than a test centre; for others, a supervised room with no technology to fail is the calmer option. There is no universally "more convenient" answer — only the one that fits your circumstances.

Acceptance — where each is (and isn't) accepted

This is the section that should drive your decision, and the one where hedging is not caution but accuracy — acceptance rules change, so confirm everything on the official source.

IELTS is one of the most broadly accepted English tests in the world: it is used for university admission across the UK, US, Canada, Australia and beyond, and, crucially, it is on the approved lists for major visa and immigration routes — for example IELTS for UKVI as a UK Secure English Language Test, and IELTS General Training within Canada's Express Entry.

Our IELTS band score requirements page collects the common academic and visa thresholds.

The Duolingo English Test's acceptance has grown dramatically, especially for university admission, where a large and expanding number of institutions now take it — particularly in North America. For study purposes it is, for many applicants, a genuinely viable option.

Where it is far more limited is visa and immigration: as of September 2026 the Duolingo test is not on the UK SELT list, Canada's Express Entry list or Australia's approved-test list (which also excludes every at-home test), so a Duolingo score — however high — cannot be used for those applications.

That is not a judgement on the test's quality; it is simply which lists it currently appears on. Two applicants with identical goals can therefore need different tests.

IELTS vs Duolingo for a UK visa (including from Peru)

The UK list is the same wherever you apply from, so the answer is identical in Lima, Lagos or Lahore: for a UK Skilled Worker, family or settlement visa, or a Student visa below degree level, you need a SELT taken at an approved centre, and Duolingo is not one.

The Skilled Worker route has required CEFR B2 since 8 January 2026, which is IELTS for UKVI 5.5 in each skill. In Peru, the British Council runs IELTS for UKVI at its Lima centres.

The only route where a Duolingo score can work is a degree-level Student visa where your university assesses your English itself and states that on your CAS. If your university has not confirmed that in writing, book IELTS for UKVI rather than risk a refused application.

The practical rule is the same one that governs any test choice: name your destination before you name your test. Check the specific university programme's admissions page and, if a visa is involved, the relevant government page, and confirm not just that your chosen test is accepted but the exact score it requires.

Which should you take?

Work through it in order. First, acceptance: if your goal is a visa or immigration route, IELTS is far more likely to be accepted than the Duolingo test as of 2026, so start by checking the official government list — this alone often makes the decision.

If your goal is university admission, confirm whether your specific programme accepts the Duolingo test and at what score; if it does and you value the lower cost and faster turnaround, it is a reasonable choice, and if it does not, IELTS remains the safe default.

Second, format and comfort. IELTS offers a live speaking interview and a supervised, technology-light environment; the Duolingo test offers an at-home, adaptive, recorded experience. If a real conversation brings out your best English, or if home internet and proctoring rules would stress you, IELTS suits you.

If you perform better against a fixed prompt and prefer avoiding a test centre, the Duolingo format may fit. Third, cost and speed matter most when a deadline is close or a budget is tight — advantages that currently favour the Duolingo test.

Whichever you choose, prepare against that test's real scale and question formats rather than generic English drills.

If you are targeting IELTS, the fastest gains usually come from objective technique in Reading and Listening — drilling by question type with trap-level feedback and per-type band tracking converts quickly into marks — while a criteria-based band calculation keeps your target concrete.

Preparation that mirrors the real test always beats preparation that merely resembles "studying English".

Conclusion

There is no universal winner in IELTS versus the Duolingo English Test — only the right test for your specific destination, format preference and budget.

The Duolingo test wins on cost, speed and convenience, and its university acceptance is genuinely broad and still growing; IELTS wins on acceptance breadth, especially for visa and immigration routes where the Duolingo test currently is not listed.

Decide by acceptance first, format second, and cost and speed third, and confirm every figure — fees, timelines and accepted-test lists — on the official source before you book. Rules change; the habit of checking the source never stops paying.
