IELTS vs TOEFL vs PTE vs Duolingo: Which Test for 2026 Admissions?
English language proficiency tests are standardized assessments used by universities, colleges, and immigration authorities to verify that non-native English speakers possess sufficient language skills for academic study or professional work. The four most widely accepted tests for 2026 admissions are IELTS (International English Language Testing System), TOEFL iBT (Test of English as a Foreign Language Internet-Based Test), PTE Academic (Pearson Test of English Academic), and Duolingo English Test (DET). Each test differs in format, scoring, cost, delivery method, and institutional acceptance, making test choice a strategic decision for applicants.

Test Overviews
IELTS (International English Language Testing System)
IELTS, launched in 1989, is jointly managed by the British Council, IDP Education, and Cambridge Assessment English. It offers two versions: Academic (for university admissions) and General Training (for immigration and work). The test assesses four skills: Listening (30 minutes), Reading (60 minutes), Writing (60 minutes), and Speaking (11–14 minutes, face-to-face with an examiner). The Speaking component is unique among major tests for its live human interaction, which some candidates find more natural but others perceive as less consistent than automated scoring.
IELTS uses a 9-band scale, with most universities requiring a minimum overall band score of 6.0 to 7.5. The test is available in over 1,600 locations across 140 countries. In 2026, IELTS remains the most widely accepted test for UK Visas and Immigration (UKVI) purposes, with the specific “IELTS for UKVI” variant required for certain visa categories.
TOEFL iBT (Test of English as a Foreign Language Internet-Based Test)
TOEFL iBT, administered by ETS (Educational Testing Service), has been the dominant English proficiency test for US universities since 1964. The current iBT format, significantly shortened in July 2023, now takes approximately 2 hours (down from 3.5 hours). It assesses Reading, Listening, Speaking, and Writing, with integrated tasks that combine multiple skills (e.g., read a passage, listen to a lecture, then speak or write about it).
TOEFL scores range from 0 to 120, with each section scored 0–30. Most US graduate programs require 80–100, while top-tier universities often demand 100+. The test is delivered at authorized test centers worldwide, with at-home testing available since 2020. TOEFL’s scoring is entirely automated for Reading and Listening, with human and AI scoring for Speaking and Writing.
PTE Academic (Pearson Test of English Academic)
PTE Academic, launched in 2009 by Pearson, is a fully computer-based and computer-scored test. It assesses English through integrated tasks such as “read aloud,” “repeat sentence,” and “write essay.” The test takes 2 hours and covers Speaking & Writing (54–67 minutes), Reading (29–30 minutes), and Listening (30–43 minutes). PTE uses a global scoring scale of 10–90, with most universities requiring 50–70 for admission.
PTE is particularly popular in Australia and New Zealand, where it is accepted for student visas and permanent residency applications. The Australian Department of Home Affairs recognizes PTE for all visa categories. In 2026, PTE is accepted by over 3,500 institutions globally, including many UK universities and an increasing number of US institutions.
Duolingo English Test (DET)
The Duolingo English Test, introduced in 2016, is the newest and most affordable option. It is entirely online, taken at home, and completed in about 1 hour. The test uses adaptive technology—question difficulty adjusts based on performance—and includes a 10-minute ungraded video interview. DET scores range from 10 to 160, with most universities requiring 105–125 for admission.
DET’s key advantages are cost ($59, significantly lower than competitors) and convenience (no test center visit required, results available within 48 hours). However, acceptance is narrower: while over 5,000 institutions accept DET as of 2026, some top-tier universities (e.g., Ivy League schools) still require IELTS or TOEFL for certain programs. DET is not accepted for UK Visas and Immigration (UKVI) or Australian student visa applications.

PTE includes unlimited free score reports.
Acceptance by Country
United States
All four tests are accepted by US universities, but acceptance varies by institution. As of 2026, over 11,500 US institutions accept TOEFL, 12,000+ accept IELTS, 2,500+ accept PTE, and 5,000+ accept Duolingo. However, many top-tier universities (e.g., Harvard, Stanford, MIT) prefer TOEFL or IELTS, with some explicitly stating they do not accept Duolingo for certain programs. The US Department of State’s Student and Exchange Visitor Program (SEVP) accepts all four tests for F-1 visa applications, though the specific test requirement is set by each university.
United Kingdom
For UK student visa (Tier 4) applications, only IELTS for UKVI (a specific test variant), PTE Academic UKVI, and TOEFL iBT (accepted by some institutions) are recognized by UK Visas and Immigration (UKVI). Duolingo is not accepted for visa purposes. Many UK universities, including the Russell Group, accept IELTS, TOEFL, and PTE, but Duolingo acceptance is limited to approximately 150 institutions as of 2026.
Australia
The Australian Department of Home Affairs accepts IELTS, TOEFL iBT, and PTE Academic for all student visa (Subclass 500) applications. Duolingo is not accepted for Australian visa purposes. Australian universities overwhelmingly prefer IELTS (used by 100% of universities) and PTE (used by 95%+), with TOEFL accepted by most but less commonly specified in admissions requirements.
Canada
Immigration, Refugees and Citizenship Canada (IRCC) accepts IELTS, TOEFL iBT, PTE Academic, and Duolingo for student visa applications under the Student Direct Stream (SDS) pathway (except Duolingo, which is not SDS-eligible). For regular study permit applications, all four tests are accepted. Canadian universities generally accept all four tests, though IELTS remains the most commonly required.

Duolingo offers the most generous free preparation: an unlimited free practice test that simulates the actual exam. IELTS and TOEFL provide limited free resources but charge for full-length practice tests. PTE’s free app includes basic practice, but full-length tests require payment.
Which Test Should You Choose?
Factors to Consider
-
Target country and visa requirements: If applying to the UK or Australia for visa purposes, IELTS or PTE are the safest choices. Duolingo is not accepted for student visas in these countries.
-
University requirements: Check each university’s specific English proficiency requirements. Some programs, especially in medicine, law, or graduate research, may require a specific test.
-
Test format preference: Candidates who prefer face-to-face speaking may choose IELTS. Those comfortable with computer-based testing may prefer TOEFL, PTE, or Duolingo.
-
Cost and convenience: Duolingo is the cheapest and most flexible (at-home testing). IELTS and TOEFL require test center visits, though TOEFL offers at-home testing.
-
Score turnaround: PTE and Duolingo provide results within 48 hours, while IELTS paper-based takes 13 days.
-
Test difficulty: While subjective, many test-takers find IELTS reading and writing more challenging, while TOEFL listening and speaking can be difficult for non-native speakers. PTE’s integrated tasks require multitasking. Duolingo’s adaptive format is shorter but less familiar.

Recent Developments (2025–2026)
In 2025, ETS introduced a new “TOEFL iBT Essentials” test, a shorter, cheaper version ($120) for admissions to community colleges and pathway programs, though it is not yet widely accepted. Pearson launched PTE Academic Online in select countries in 2025, allowing at-home testing with remote proctoring, but acceptance remains limited compared to test-center versions. Duolingo expanded its acceptance list by 15% in 2025, adding over 700 new institutions globally.
In 2026, the Australian Department of Home Affairs announced it would review its list of accepted English tests, with potential changes to include Duolingo for certain visa categories by 2027. No changes have been confirmed as of May 2026.
