Columbia’s Graduate School of Arts and Sciences asks for IELTS Academic 7.5. Princeton’s Graduate School sets no minimum at all.
This guide compares IELTS band score requirements at top US universities as published in October 2026: overall floors, section minimums, the TOEFL rescale of January 21, 2026, and the higher Speaking scores tied to teaching roles after admission.
IELTS Band Score Requirements at Top US Universities
What IELTS Score Do Top US Universities Require?
Six of the ten graduate schools below publish 7 as their overall IELTS figure. Columbia GSAS and Illinois full-status admission sit at 7.5, the highest figure in this set.
| Institution | IELTS Academic overall | How the figure is framed |
|---|---|---|
| Columbia GSAS | 7.5 | Required minimum |
| University of Illinois Urbana-Champaign | 7.5 full status / 6.5 limited status | Placement test below 7.5 |
| Harvard Griffin GSAS | 7 | Minimum, plus Speaking 6.5 |
| Cornell Graduate School | 7.0 | Minimum for research and professional degrees |
| UC Berkeley Graduate Division | 7 | Minimum, plus section floors from Jan 21, 2026 |
| Georgia Tech | 7 | Institute minimum with section floors |
| UChicago Harris School of Public Policy | 7 | No sub-score below 7 |
| MIT Graduate Admissions | 7 | Recommended; department minimums supersede |
| Purdue Graduate School | 6.5 | Minimum with section floors |
| Princeton Graduate School | None | No minimum score requirement |

MIT’s 7 is a recommendation, and its page states that department minimums supersede it. Princeton’s Graduate School has no minimum, though its departments may set one.
Illinois runs two tiers. Applicants at 6.5 can enter on limited status but must sit the English as a Second Language Placement Test before enrolling.
Columbia applies its rule by the country that awarded the undergraduate degree, regardless of citizenship. These rules screen a large non-native group, sized in our look at how many people speak English worldwide.
Section Floors Drop to 5.5 in Writing at Georgia Tech and Purdue
| Institution | Overall | Reading | Listening | Speaking | Writing |
|---|---|---|---|---|---|
| UChicago Harris | 7 | 7 | 7 | 7 | 7 |
| Georgia Tech | 7 | 6.5 | 6.5 | 6.5 | 5.5 |
| UC Berkeley (tests from Jan 21, 2026) | 7 | None | None | 6.5 | 6.5 |
| Harvard Griffin GSAS | 7 | None | None | 6.5 | None |
| Purdue Graduate School | 6.5 | 6.5 | 6.0 | 6.0 | 5.5 |
Source: UChicago Harris, Georgia Tech Graduate Education, UC Berkeley Graduate Division, Harvard Griffin GSAS and Purdue Graduate School admissions pages, as published October 2026
Overall bands hide the section rules. Georgia Tech sets 7 overall but accepts 5.5 in Writing, and Purdue pairs a 6.5 overall with the same Writing floor.
UChicago Harris has the strictest row: no sub-score may fall below 7. An applicant with 7.5 Reading and 6.5 Writing can reach 7 overall and still miss that rule.
Berkeley’s Speaking and Writing floors apply to tests taken on or after January 21, 2026. Tests from June 1, 2025 to January 20, 2026 need 7 overall alone.
How Do These Floors Compare With Average IELTS Scores?
IELTS publishes means for its objectively marked sections. Georgia Tech’s 6.5 Reading floor sits above the 2024-25 Academic Reading mean of 6.32.
| Test section | Mean band | Standard deviation | Standard error of measurement |
|---|---|---|---|
| Listening (Academic and General Training) | 6.45 | 1.36 | 0.43 |
| Academic Reading | 6.32 | 1.26 | 0.36 |

IELTS Band Score Requirements at Top US Universities After the TOEFL 1–6 Rescale
ETS moved the TOEFL iBT to a 1–6 scale on January 21, 2026, and score reports carry a comparable 0–120 figure until January 2028. Its IELTS table pairs IELTS 7.5 with a TOEFL total of 5.5 and IELTS 7 with 5.
Source: ETS, TOEFL Score Scale Update guide for institutions, 2026
ETS recommends a 5 for institutions that required 100 on the old scale and 4.5 for those that required 90. Not every university followed that guidance.
| Institution | IELTS overall | TOEFL, tests before Jan 21, 2026 | TOEFL, tests from Jan 21, 2026 |
|---|---|---|---|
| Columbia GSAS | 7.5 | 100 | 5.5 |
| Harvard Griffin GSAS | 7 (Speaking 6.5) | 95 (Speaking 23) | 5 (Speaking 4.5) |
| UC Berkeley Graduate Division | 7 (Speaking and Writing 6.5) | 90 | 5 (Speaking and Writing 4.5) |
Source: Columbia GSAS, Harvard Griffin GSAS and UC Berkeley Graduate Division admissions pages, as published October 2026
Columbia’s 5.5 matches its IELTS 7.5 on the ETS table, not the 5 that ETS suggests for a former 100. Berkeley moved from 90 to 5, where ETS suggests 4.5 for a former 90.
Speaking shows the same pattern. ETS pairs TOEFL Speaking 4.5 with IELTS 7, while Harvard and Berkeley pair TOEFL Speaking 4.5 with IELTS Speaking 6.5.
Why Does Speaking 8.0 Matter After Admission?
Teaching roles carry a higher bar than admission. At Princeton, Cornell and Harvard, IELTS Speaking 8 is the level that avoids further oral checks.
| Institution | IELTS threshold | What it decides |
|---|---|---|
| Princeton Graduate School | Speaking below 8.0 | Test required on enrollment |
| Cornell Graduate School, Tier A | 7.0 overall with Speaking 8.0 | TA role with no extra language assessment |
| Cornell Graduate School, Tier B | 7.0 overall | Assessment and support plan before a TA role |
| Harvard Griffin GSAS | Speaking 8 and above | Oral English requirement met |
| Harvard Griffin GSAS | Speaking 7 to 7.5 | Oral proficiency interview in first term |
Source: Princeton Graduate School, Cornell Graduate School (Summer and Fall 2026 guidelines) and Harvard Griffin GSAS English Language Proficiency policy, as published October 2026
Princeton publishes no admission minimum, so its central IELTS number is the Speaking 8.0 trigger after enrollment. The same check applies to TOEFL Speaking below 27 and Duolingo Conversation below 125.
Harvard admits at Speaking 6.5 and treats Speaking 8 as meeting its oral requirement for teaching fellows. Berkeley also states that its oral English level for Graduate Student Instructor posts is higher than its admission level.

Which IELTS Formats Do Top US Universities Reject?
Format rules vary as much as band floors. Berkeley rejects IELTS Indicator and One Test Retake, while Georgia Tech accepts IELTS Indicator Academic scores.

| UC Berkeley Graduate Division | Accepted | Not accepted | Not accepted |
| MIT Graduate Admissions | Not stated on page | Not stated on page | Not accepted |

Score age rules differ too. Berkeley will not accept tests taken before June 1, 2025 for Fall 2027, and Harvard takes Fall 2027 scores from tests dated January 5, 2025 or later.
Columbia GSAS accepts IELTS Academic scores in electronic format only. For self-study between attempts, our figures on language learning app usage cover the market outside formal test prep.
Cornell Flags Higher Minimums for Fall 2027
Cornell’s Graduate School says minimum scores are expected to increase for summer and fall 2027 admission. It has not posted the new figures and tells applicants to check back in mid-October.
Its current 7.0 overall applies to Summer and Fall 2026 admission until that update appears.
