Duolingo English Test 2026 Guide: Cost, Scoring, University Acceptance, Prep

Updated August 2026 · Fees, formats and policies are indicative — verify on the official test websites

The Duolingo English Test is a trademark of Duolingo, Inc. This page is an independent guide and is not affiliated with or endorsed by Duolingo.

The Duolingo English Test (DET) is the budget disruptor of English proficiency testing: about US$65 (≈ ₹5,500 — a third of IELTS), taken from home in about an hour, results in roughly two days. For students applying to universities that accept it, it removes both cost and logistics from the English-test step.

The catch is acceptance: strong and growing in the US, patchier in other countries, and separate visa English rules can apply regardless of what the university accepts. Verify acceptance for every university and the visa rules for your destination before making DET your only test. Details below are indicative for 2026 — check englishtest.duolingo.com for current fees and rules.

What scores universities want

Equivalence tables are approximations published by Duolingo and individual universities — a university's own stated DET requirement always wins.

DET score	Rough equivalence	What it gets you
105–115	≈ IELTS 6.0–6.5	The floor at many accepting universities
120	≈ IELTS 6.5–7.0	The most common masters requirement among DET-accepting programs
130+	≈ IELTS 7.0–7.5	Comfortable for competitive programs that accept DET

The rules that get tests invalidated

Alone in a quiet, well-lit room; face visible the whole time; no headphones or earphones; no second monitor; no phone in reach.
Eyes on the screen — repeatedly looking away (at notes, a phone, another person) is the most common proctoring flag.
No talking except when a task asks you to speak; no virtual cameras or screen-sharing software running.
Every test is human-reviewed after AI proctoring before certification — an invalidated test wastes the fee and days of timeline, so over-comply.

Who should (and shouldn't) rely on DET

Good fit: US-focused applicants whose entire university list confirms DET acceptance; budget-constrained applicants; students in towns far from IELTS/TOEFL centres; anyone needing a fast score late in the cycle.
Bad fit: lists spanning countries where acceptance is patchy or visa English rules require IELTS/TOEFL-class tests; programs (some nursing, education, licensure tracks) that exclude DET explicitly.
Hedge strategy: DET first for speed and cost; if a dream university on your list doesn't accept it, one IELTS/TOEFL sitting covers the rest — the DET fee is small enough that this rarely wastes money.
Prep: the official free practice test mirrors the adaptive format — take it at least twice. The question styles (dictation, read-aloud, fill-in-the-blanks, picture description) reward familiarity; a week of daily practice tests moves scores.

Speaking fluency is built out loud, not in books

Interviews decide the rest of your abroad journey too — admissions, visas, assistantships. Practise them with Phiny's AI interviewer and build the spoken-English reps that exams and interviews both reward. Text interviews are free and unlimited.

Frequently asked questions

How much does the Duolingo English Test cost?

About US$65 (≈ ₹5,500) per attempt, with discounted two-test bundles available — roughly a third of IELTS or TOEFL. Fees are revised periodically; check the official Duolingo English Test site.

Which universities accept the Duolingo English Test?

Thousands of programs, with the strongest acceptance among US universities; acceptance elsewhere (UK, Canada, Australia, Germany) is growing but per-university and sometimes per-program. The official site has a searchable acceptance list — verify every university on your shortlist, and check your destination's visa English rules separately.

What DET score is equivalent to IELTS 6.5?

Roughly 110–120 on the 10–160 scale, per published equivalence tables. Treat equivalences as approximate — the DET requirement a university states on its own admissions page is the number that matters.

Is the Duolingo English Test easier than IELTS?

It is shorter, cheaper and more convenient, but calibrated to measure the same proficiency — a 6.5-level speaker scores 6.5-equivalent on both. The adaptive format and unusual question types reward practice-test familiarity, so the free official practice test is essential.

Can my Duolingo test be rejected?

Yes — every test goes through AI plus human proctoring review, and rule violations (looking away repeatedly, headphones, someone entering the room) invalidate it. Follow the environment rules exactly; an invalidated attempt costs you the fee and several days.
