Duolingo to IELTS Score Converter 2026

In Duolingo's concordance, DET 105 is the lowest score that corresponds to IELTS 6.0, and the IELTS 6.0 range covers DET 105, 110 and 115. IELTS 6.0 is a common minimum for undergraduate programmes and foundation courses. A score of 100 falls in the IELTS 5.5 range (DET 95–100).

If a course asks for IELTS 6.0 and accepts the Duolingo English Test, check the DET minimum it publishes — many institutions set their own DET figure rather than converting from IELTS. Always confirm acceptance directly with your target university, as Duolingo is not yet universally recognised.

DET 120 is the lowest score that corresponds to IELTS 6.5 in Duolingo's concordance; the IELTS 6.5 range covers DET 120 and 125. IELTS 6.5 is a common minimum for postgraduate programmes. DET 110 and 115, which older tables placed at IELTS 6.5, correspond to IELTS 6.0 in the current Scoring Guide.

If your target programme asks for IELTS 6.5 and accepts Duolingo, look up the DET minimum it states rather than relying on a conversion — some institutions ask for a different DET score than this table suggests.

DET 130 is the lowest score that corresponds to IELTS 7.0 in Duolingo's concordance; the IELTS 7.0 range covers DET 130 and 135. IELTS 7.0 is a frequent requirement for competitive postgraduate programmes.

If you are targeting highly ranked universities that accept DET, 130 is the score that lines up with IELTS 7.0. Be aware that some competitive programmes — particularly in the UK, Australia, and for professional registration — may not accept Duolingo at all, regardless of your score.

DET 140 is the lowest score that corresponds to IELTS 7.5 in Duolingo's concordance; the IELTS 7.5 range covers DET 140 and 145. Above that, DET 150–155 corresponds to IELTS 8.0 and DET 160 to IELTS 8.5–9.

If you have this score and are considering IELTS instead, be aware that IELTS 7.5 requires consistently strong performance across all four sections, and the speaking interview and writing task formats may be an adjustment if you are accustomed to DET's computer-adaptive format.

Test duration: The Duolingo English Test takes approximately 1 hour to complete. IELTS takes 2 hours and 45 minutes (or longer if you include the speaking interview scheduled separately). This is one of Duolingo's biggest advantages for test takers who prefer a shorter, more focused assessment.

Cost: The DET usually costs considerably less per attempt than IELTS, which matters if you expect to need more than one attempt. Both fees vary by country and change over time, so check the current price on each official website before you book.

Test format: DET is an AI-adaptive test taken at home on your own computer. Questions adjust in difficulty based on your responses. IELTS follows a fixed format with predetermined question types across four distinct sections, taken at an authorised test centre (or at home for IELTS Online). IELTS Speaking is a face-to-face interview with a certified examiner.

Acceptance gaps: While over 5,000 institutions accept the Duolingo English Test, many universities, immigration authorities, and professional registration bodies still do not recognise it. IELTS is accepted by over 11,000 organisations in 140+ countries. For immigration purposes specifically, Duolingo is generally not accepted — IELTS remains the standard for visa applications in Canada, Australia, the UK, and New Zealand.

Immigration is the clearest case for IELTS. Canada, Australia, the UK, and New Zealand require IELTS (or a small number of approved alternatives) for skilled migration, permanent residency, and citizenship applications. The Duolingo English Test is not accepted for any of these immigration pathways. If your goal involves a visa, IELTS is almost certainly required.

Professional registration bodies in healthcare, engineering, accounting, and law overwhelmingly specify IELTS. Nursing boards in Australia and the UK, medical councils, and engineering accreditation bodies list IELTS as the preferred or only accepted English proficiency test. If your profession requires registration in an English-speaking country, check the specific board's requirements — most do not accept Duolingo.

Wider university acceptance also favours IELTS. While Duolingo adoption has grown rapidly, many universities outside the US still prefer or require IELTS. UK Russell Group universities, most Australian Group of Eight universities, and many European institutions specify IELTS. If you are applying to multiple countries, IELTS gives you the broadest coverage with a single test result.

Budget is one of the strongest reasons to choose Duolingo. A DET attempt usually costs much less than an IELTS test, so if you are a student with limited funds or expect to need multiple attempts, the savings can be substantial. Check current fees on both official websites, as prices differ by country.

Convenience and speed are also major advantages. You can take the DET at home, on your own computer, at any time — no need to book a test centre weeks in advance. Results are available within 48 hours, compared to 3-13 days for IELTS. If you have a tight application deadline or live far from a test centre, Duolingo eliminates logistical barriers.

If you perform better in a low-pressure environment and prefer testing from the comfort of your own home, Duolingo may suit you better. There is no face-to-face speaking interview, no crowded test room, and no strict scheduling constraints.

If you are switching from Duolingo to IELTS, your core English skills — vocabulary, grammar, reading comprehension, and listening ability — transfer directly. What changes is the format, timing, and the way you demonstrate those skills under exam conditions.

The biggest adjustment is the Speaking section. DET speaking involves short recorded responses to on-screen prompts without any human interaction. IELTS Speaking is an 11-14 minute face-to-face interview with a certified examiner who asks follow-up questions and evaluates your ability to sustain extended answers. This conversational format requires practice — most DET-to-IELTS switchers find it the hardest section to adapt to.

IELTS Writing is also significantly different. DET writing tasks are short and integrated into the adaptive test flow. IELTS requires a 150-word Task 1 response (Academic: data description; General: letter) and a 250-word Task 2 essay with clear paragraphing, developed arguments, and sophisticated cohesion. Neither has a direct DET equivalent, so dedicated practice with timed conditions is essential.

For Reading and Listening, the core skills overlap, but IELTS uses specific question types — True/False/Not Given, matching headings, sentence completion, map labelling — that require targeted strategies. Spend time learning these IELTS-specific formats rather than just drilling general comprehension, as the question design can trip up even strong English users who are unfamiliar with them.
