TOEFL vs IELTS vs Duolingo for US universities

Many US colleges ask non-native English speakers for an English test, but the most selective ones differ: Harvard, MIT and Stanford do not require one, and Yale requires one only if you have had less than two years of English-medium schooling. The Duolingo English Test is the cheapest, at US$70. Where the SAT or ACT is required, an English test does not replace it. The test is one step of applying to US universities from abroad.

Last reviewed 22 September 2026. Valid for the 2026-27 cycle (fall 2027 entry).

Who requires a test

For the 2026-27 cycle, Harvard, Stanford and MIT do not require an English test, and Bowdoin makes it optional. Yale, Cornell, the University of California and Purdue require one, each with an exemption based on schooling in English.

Minimum scores at representative colleges

In 2026-27, minimum scores run from TOEFL 4.5, IELTS 6.5 and Duolingo 115 at the University of California and Purdue to TOEFL 5, IELTS 7.5 and Duolingo 130 at Cornell, with the TOEFL on its new 1 to 6 scale.

The University of California's scores are minimums to be considered, not targets. UC takes only the best score from a single sitting and does not accept IELTS One Skill Retake or TOEFL MyBest scores.

The new TOEFL scale

Since 21 January 2026, the TOEFL iBT reports scores from 1 to 6, in half points, for Reading, Listening, Speaking and Writing. The overall score is their average. Until January 2028, the score report also shows a comparable score on the old 0 to 120 scale: a 5, for example, compares to about 95 to 106. That matters because many colleges still publish minimums on the old scale, such as MIT's 90 (or 5) and Cornell's 100 for tests taken before January 2026.

Ways to prove English without a test

You can often skip the test in 2026-27. Yale, Cornell and Purdue waive it after enough years at an English-medium school, and the University of California and Purdue accept certain AP, IB, SAT or ACT scores instead.

  • English-medium schooling: Yale, Cornell and Purdue waive the test after a set number of years at an English-medium school.
  • Other scores: the University of California accepts an AP English Language or Literature score of 3 or higher, IB English A at set grades or an ACT English Language Arts score of 24 or higher. Purdue accepts an SAT Evidence-Based Reading and Writing score of 600 or an ACT English score of 26, from the last two years.
  • Self-reporting: Cornell and Purdue let you self-report scores and ask for official ones only after admission.
