There is no blanket rule that an English-medium CBSE or ISC education replaces TOEFL or IELTS. Yale, Princeton, Cornell, Penn, Columbia and NYU all waive the test after two to four years of English-medium schooling with no country restriction, which covers most Indian applicants. Carnegie Mellon, Michigan, Illinois, Toronto and McGill do not waive for Indian schools at all. Singapore and Hong Kong universities accept the Class 12 English mark outright. The rule is per university, and the only safe method is to read each one's own page.
The question is worth asking carefully because the search results are almost entirely consultancy pages selling MOI certificates. When I looked for where Indian students actually discuss this, there was no substantial forum thread at all; the space is filled by agents whose product is a letter from your principal. That letter is accepted by far fewer universities than those pages suggest.
Three different requirements, often confused
The admission requirement is set by the university, and this is where waivers live. The visa requirement is set by the government; for the UK it is a separate legal test that does not follow the university's decision automatically, while the US and Canada impose no separate English test for the visa itself. The evidence is what a waiver actually needs: some universities accept a transcript showing years of English-medium study, some want a specific board English percentage, a few want a letter, and several want a test regardless.
A family that clears the first and forgets the second books an IELTS in July at panic prices. A family that assumes all three are the same skips a test that Carnegie Mellon was always going to require.
United States: waiver rules at named universities
Everything below is from each university's own admissions page as of September 2026. Confirm before you rely on it, because these pages change between cycles. Harvard and Stanford require no English test at all, so they are not in the table.
| University | Waives for English-medium schooling? | Years required | Does CBSE or ISC qualify? | SAT or ACT route? |
|---|---|---|---|---|
| MIT | No requirement to waive; a test is recommended only if you have used English fewer than five years or do not speak it at home or in school | n/a | n/a | No |
| Yale | Yes | 2 or more | Yes | No |
| Princeton | Yes | 3 or more at secondary school | Yes | No |
| Columbia | Yes | Entire secondary career | Yes | Yes: SAT Reading and Writing 700, or ACT English or Reading 29 |
| Cornell | Yes | 4 | Yes | No |
| Penn | Yes | 3 or more, school or college | Yes | No |
| NYU | Yes | 3 most recent consecutive years | Yes | No, and refused in writing |
| Purdue | Yes, at their discretion | 3 | Likely | Yes: SAT Reading and Writing 600, or ACT English 26 |
| Georgia Tech | Yes, on completion of secondary study where English is the official language of instruction | Not stated | Likely | Yes: SAT Reading and Writing 480, or ACT English 17 |
| Northeastern | Yes | 4 consecutive | Likely, though no Indian board is named on the evidence list | No |
| Boston University | At the discretion of the Board of Admissions; no criteria published | Unknown | Unknown | No |
| UMass Amherst | Yes, but only for "a British or American curriculum" | 4 | No | No |
| Illinois Urbana-Champaign | Country-based only, and India is not on the list | 3 | No | Test required if no SAT or ACT |
| Michigan | Country-based, and India is not on the list | 4 | No | Score alone is not sufficient |
| Carnegie Mellon | No waiver of any kind published | n/a | No | No |
Three of these deserve a sentence. NYU is the clearest written refusal of the exam route, worth quoting because so many Indian families assume the opposite: NYU "does not waive the English language requirements based on the following exam results: SAT, ACT, AP, IGCSE, AS/A-Levels, International Baccalaureate Diploma (IBDP), including IB English A or B HL and SL, and other local national exams conducted in English." Three years of English-medium schooling works there. A 780 on the SAT does not. Columbia is the one Ivy with a score route, so a student at 700 or above on SAT Reading and Writing has the waiver already. Michigan's wording is a conjunction, not a choice: the exemption needs the score and four years in one of a listed set of countries, and India is not among them, though American-pattern and British-pattern international schools in India may still qualify.
United Kingdom: the board mark, and the visa
Four universities publish a CBSE or ISC English percentage that satisfies the requirement outright.
| University | CBSE or ISC Class 12 English accepted | Mark required | Scope |
|---|---|---|---|
| Imperial College London | Yes, CBSE and CISCE boards only | 70 percent | Undergraduate and postgraduate |
| UCL | Yes | 85 in English Core (CBSE) or English compulsory (CISCE), and the qualification must be no more than two summers old at enrolment | Undergraduate, all requirement levels |
| Warwick | Yes, English Core, English Elective or English Language and Literature | 75, 80 or 85 percent depending on the course band, at first attempt | Undergraduate |
| Edinburgh | Yes | 75 percent, valid three and a half years | Undergraduate |
Oxford, LSE and King's College London list no Indian qualification, and King's states that a test not on its list cannot be accepted. Oxford does have a medium-of-instruction exemption for applicants "educated full-time in English for at least the two most recent years before applying" who remain in full-time education in English until they finish school, requested through the college making the offer rather than in advance. Manchester says it may accept Indian Standard XII English depending on the board and score, but publishes no number.
One time-sensitive point. The TOEFL iBT moved to a new 1 to 6 scale on 21 January 2026, and Oxford states that "TOEFL tests taken from 21 January 2026 are not accepted and do not meet the English language condition" while the change is under review. If you are applying to Oxford and need a test, sit IELTS. Most other universities now publish two thresholds, one per scale, so read the date column on their page carefully.
The visa is separate. For a bachelor's or master's at any of the universities above, no UKVI-approved test is legally required: the university self-assesses your English and states so on the Confirmation of Acceptance for Studies. A UKVI secure English language test becomes mandatory for courses below degree level, including a standalone foundation year or a pre-sessional English course, even at a top provider. That is the trap. A student who accepts a foundation-year offer after a near miss suddenly needs IELTS for UKVI at ₹19,250, on a deadline. The UK destination guide covers the rest of the visa file.
Canada, Australia, Singapore and Hong Kong
| University | Board English accepted in place of a test | Threshold or condition |
|---|---|---|
| UBC | Yes | 75 percent in senior English for CBSE or CISCE schools; UBC reserves the right to exclude schools |
| Waterloo | Yes | Four most recent years taught in an entirely English-language school system, evidenced by transcripts or an official hardcopy principal's letter |
| McMaster | Yes, at their discretion | At least four years at an accredited English-medium secondary school |
| Toronto | No | Exemption needs four years in a country where the dominant language is English; Grade 12 English is refused in writing |
| McGill | No | Proof required even where English was the main language of instruction at a non-English-country school |
| Melbourne | Yes | Pass the English subject in CBSE or ISC; valid 24 months |
| UNSW | Yes | C1 in CBSE English Core, or ISC 70 percent; higher for Business, and excluded for Education, Law, Medicine and several health programmes |
| ANU | Yes | C2 in CBSE English Core, or ISC English graded 1 to 7 |
| Monash | Yes, assessed case by case | No published mark; the English subject is assessed on application |
| Sydney | Not as a named qualification | Admitted through a general clause on English-medium senior secondary study; course minimums are high, IELTS 7.0 to 7.5 for most degrees |
| NUS | Yes, no test needed for Indian Standard 12 | Law is separate: IELTS 7.0, TOEFL 100, SAT Reading and Writing 700 or AP English Language 4 |
| NTU | Yes | "If English is your medium of studies, taking any of the English proficiency tests will not enhance your chances of admission" |
| HKU | Yes | 90 percent in AISSCE, ISC or HSC English |
| HKUST | Yes | 80 percent in AISSC or ISC English |
| CUHK | Yes, and uniquely accepts state boards | 80 percent in Class 12 English from an Indian central or state board |
The Singapore rows match what applicants report: on the hotcourses forum an answer about NUS and NTU admission from India states simply that "CBSE applicants need no SAT and no IELTS", and how to get into NUS or NTU from India covers what does decide those applications. The Canada rows are the ones that catch families out, because Toronto and McGill sit at the top of most Indian shortlists and neither waives. See the Canada destination guide for the rest of that application.
The MOI certificate, honestly
An MOI certificate is a letter on institutional letterhead from a principal, registrar or controller of examinations, stating that a named student's programme was taught and examined in English. It carries no score. It is the product Indian consultancies sell hardest, and it is accepted by far fewer universities than that marketing implies.
Accepted, in writing: the University of Waterloo, at undergraduate level, which asks for "an official hardcopy letter from your previous schools' principal(s)" sent directly by the school and states that emailed letters will not be accepted. Monash and UNSW accept a registrar letter for prior tertiary study, and Melbourne accepts one but excludes institutions located in India by name.
Refused, in writing: Manchester, whose page states that "confirmation that English was the mode of instruction at your university is not accepted as evidence". McGill, which requires proof "even if you have been attending a school at an accredited institution (in a non-English country) where English is the main language of instruction". Toronto, which has no medium-of-instruction route. And UK Visas and Immigration, where the four legal routes to proving English are exhaustive and a school letter is not one of them.
Everywhere else, the useful document is your Class 12 English mark on an official transcript. Ask for the letter only where a university has asked for it.
Duolingo English Test: where it works and where it does not
Duolingo states that more than 6,500 programmes accept the test and that all eight Ivy League universities do. Verified undergraduate minimums cluster in three bands: 115 to 120 at Purdue, UMass, MIT, Yale, Toronto and McMaster; 125 to 130 at UBC, HKUST, Cornell, Penn and Illinois; and 135 at Columbia, NYU and Carnegie Mellon, which requires 135 on every subscore.
It does not work at the University System of Georgia, which includes Georgia Tech, whose page says Duolingo results are welcome as supplementary material but do "not satisfy USG requirement". Michigan does not accept it. Neither do Oxford, Cambridge, LSE or King's, nor any of Melbourne, Sydney, UNSW, Monash or ANU. CUHK is the only Hong Kong university with an explicit written refusal, and will read a Duolingo score for reference while still requiring another test.
The case for Duolingo is cost and speed: taken at home, an hour long, results in two days. Duolingo publishes no price on any public page; the widely reported figure is USD 70, roughly ₹5,900 against ₹19,000 for IELTS, so treat that as indicative and check inside the purchase flow. It also runs an Access Program providing free test codes to eligible students. The case against it is list coverage: if one university on your list refuses Duolingo, you are taking IELTS or TOEFL anyway. Build the list first, then choose the test.
How to request a waiver, in order
- Find the page, not the blog. Search the university's own domain for "English proficiency" or "English language requirements". Consultancy summaries are stale more often than not.
- Identify which route you qualify for. Years of English-medium instruction, a board English percentage, or an SAT or ACT subscore. Write down the exact wording and the exact number.
- Check your transcript already says it. Most waivers need nothing more than a transcript showing English as a subject and the medium of instruction stated on the school profile. If the profile does not say it, ask the school to add one line. That line does more work than an MOI certificate.
- Use the portal, not email. Many universities have a waiver form or a checkbox inside the application. Where there is none, send one short email to international admissions with your applicant ID, the policy clause you are claiming and the evidence attached, and keep the written reply.
- Ask in September, not in December. Waiver decisions take two to four weeks in peak season, and if the answer is no you need a test date. The deadlines resource has the cycle dates to work back from.
When to just take the test
Take it, without arguing, in five situations.
- One university on your list does not waive. Carnegie Mellon, Michigan, Illinois, Toronto or McGill on a list means a test, so take it once and send it everywhere.
- Your board English mark is below the threshold. Below 75 percent, most of the waivers above are closed to you. Below 80 percent for Hong Kong, book a test for the autumn so the score exists before the November round.
- You are applying to a course with a carve-out. Law, medicine, education, nursing and several business programmes set their own higher bars at UNSW, NUS, HKU and across the UK, regardless of the central policy.
- A foundation year or pre-sessional course is a realistic outcome in the UK. That triggers a UKVI secure English language test as a matter of immigration law.
- You are a strong applicant with a weak board English mark. A 7.5 on IELTS neutralises a 68 in English Core in a way no letter does.
The costs and turnaround, from the official pages:
| Test | Fee in India | Results | Availability |
|---|---|---|---|
| IELTS Academic (IDP, the sole provider in India since 2021) | ₹19,000 on computer or paper; reschedule ₹4,750 | 2 days on computer, 7 days on paper | Computer up to three times a day; paper up to four times a month |
| IELTS for UKVI Academic | ₹19,250 | 1 to 5 days | As above |
| TOEFL iBT | USD 173 before taxes, about ₹14,500 | 3 days in your ETS account | More than 170 test dates a year at centres; Home Edition four days a week |
| PTE Academic | ₹18,900 | About 48 hours | 57 test centres in India |
| Duolingo English Test | Billed in USD, no India price; widely reported as USD 70, about ₹5,900 | 2 days | On demand, from home |
Budget four to six weeks from decision to usable score, with a buffer for a retake. That is the same window the SAT occupies in Grade 12, which is why choosing between the SAT and ACT and settling the English test belong in one conversation, sequenced against everything else in the Plinth method. Where a score is needed the preparation is short and mechanical, and test preparation for it should not consume a term.
Where this advice stops
Every table here is a snapshot of September 2026, and several of these pages changed during the last cycle. Course-level requirements override central policy at Edinburgh, Warwick, UCL, Imperial, UNSW, Melbourne and Sydney, so a waiver that holds for engineering may not hold for law. Postgraduate policy is stricter almost everywhere; MIT's graduate office exempts only degree holders from six English-speaking countries and states that it does not accept exemption requests at all. And a waiver is an administrative rule about evidence, not a judgement about your English. If your writing is genuinely weaker than your marks suggest, the test score is the least of what a personal statement will reveal.
