Whether a US institution accepts IELTS Online or IELTS One Skill Retake is a rule each institution sets for itself, and the examples read for this page disagree with one another. Below are what six institutions' own pages say and what two other organisations say, all read in October 2026. They are examples, not a list of US requirements, and every rule belongs to the institution named. Pages change, so open the linked page, and ask the institution before you book.
What six institutions say, side by side
The table gives each rule as the institution's own page words it. "Silent on the page read" means the page linked in that row does not mention that format. It does not mean the institution has no rule, and another page of the same institution may say something different.
| Institution and page | IELTS Online | One Skill Retake |
|---|---|---|
| University of California, undergraduate international applicants (first-year and transfer) | Silent on the page read | Not accepted |
| MIT Graduate Admissions | Silent on the page read | Not accepted |
| Yale's Graduate School of Arts and Sciences | Not accepted | Not accepted |
| University of Illinois Urbana-Champaign, graduate admissions | Accepted (Academic test) | Not accepted |
| University of Maryland, College Park Graduate School | Accepted (IELTS Academic Online) | Accepted |
| George Mason University | Silent on the page read | Accepted |
Count the rows and the split is plain: four of the six pages say One Skill Retake is not accepted and two say it is, while on IELTS Online one says no and two say yes. That is a count of the pages read here, not of US universities. The useful point is that the same two formats get different answers: Illinois accepts the online test but not the retake, Maryland accepts both, and Yale accepts neither. A rule on one page tells you nothing about another institution's rule.
Reading each rule carefully
University of California (undergraduate): one sitting
The University of California page for international applicants says UC does not accept IELTS One Skill Retake, and that only the highest composite score from a single sitting is allowed. The page is written for first-year and transfer applicants. Read the rule as being about sittings: one test, one sitting. The page read does not mention IELTS Online.
Yale's Graduate School of Arts and Sciences: three refusals in one sentence
Yale's Graduate School of Arts and Sciences is the only university example here that turns IELTS Online away. Its standardized test FAQ says in one sentence that the General Training module is not accepted, IELTS Online is not accepted and One Skill Retake is not accepted. The General Training point is Yale's own rule; which version you need is for the institution reading your result to say, as Academic or General Training explains.
University of Illinois Urbana-Champaign graduate admissions: online yes, retake no
The graduate admissions page for international applicants at the University of Illinois Urbana-Champaign says the IELTS Academic test, "in person and online", is accepted for admission. The same page says it does not accept IELTS One Skill Retake scores. So an institution that accepts the online test has not necessarily accepted a retake score.
University of Maryland, College Park Graduate School: both formats, but not paper forms
The Maryland Graduate School page lists the IELTS Academic Online among the tests it accepts and says the Graduate School also accepts the IELTS One-Skill Retake. A separate note on the same page says the Graduate School will not accept paper IELTS test report forms, and the page adds that individual programmes may hold their applicants to more stringent requirements. If you plan to use an online or retake result there, read the page itself; our guide to sending IELTS scores to US universities covers the process in general.
MIT Graduate Admissions and George Mason University
MIT Graduate Admissions says on its standardized tests page that it does not accept IELTS One Skill Retake (OSR) scores. George Mason University's English language requirements page says IELTS One Skill Retake scores are accepted. Neither page mentions IELTS Online. For the score numbers these institutions publish, see IELTS scores at US universities.
Beyond universities: two professional examples
The same formats matter outside admissions, and the two examples read here point in opposite directions.
- TruMerit. Its VisaScreen page (VisaScreen is TruMerit's service for health workers) says TruMerit does not accept the at-home versions of English language proficiency exams. The sentence is about at-home exams in general and does not name IELTS Online, so read the page for yourself. IELTS for nurses moving to the US covers VisaScreen and state board rules. This page gives no visa or immigration advice and does not say who needs VisaScreen.
- AAVSB. The American Association of Veterinary State Boards publishes a page about the PAVE application, part of its International Pathway for Veterinarians, which says IELTS Academic can be taken in person or online. The same page sets conditions of its own, such as minimum scores and a rule that all section requirements be met within one exam, so read it in full.
What ielts.org tells you to do
The ielts.org One Skill Retake page recommends that you check with the organisation directly before you book the retake. A webinar transcript on ielts.org's page for organisations says organisations do need to let IELTS know that they accept one skill retake results. Together these fit what the examples show: acceptance is a decision each organisation makes for itself, so the existence of the retake is no reason to assume your institution accepts it. How the retake works is explained in One Skill Retake or a full retake, so this page does not repeat it.
Acceptance is half the question: can you sit it in the US?
Even when an institution accepts a format, you need somewhere to sit it. The ielts.org test centre finder with the One Skill Retake box ticked returned no US centre on 24 October 2026. That is a snapshot, not proof that no centre offers it, because ielts.org says to check with the centre, so ask before you book the full test. For IELTS Online, the online IELTS tutor page for the USA explains why its availability in the US is not confirmed, and the US test centre listings and computer-delivered IELTS in the US show what the finder lists.
A checklist before you book
- Name the institution and the page for your level and programme. The six examples are six pages, each written for one audience, such as UC's first-year and transfer applicants. Another office of the same university may publish its own rule, and the Maryland page itself says individual programmes may hold applicants to more stringent requirements. This page cannot tell you which rule applies to you.
- Look for the words "online" and "retake" on that page. A page that says nothing is not a yes. If it is silent, ask the admissions office, as ielts.org recommends.
- Check the test version as well. The Yale, Illinois and Maryland pages above all name the Academic test, so look at which version the page for your programme names.
- Ask before you book, not after. Keep the reply, because rules and wording change.
- Then ask the centre whether the format you want is open to you on your date.
Examples, not a list. This page does not tell you what your institution accepts. Only that institution can, and it may change its rule.
Where lessons with Mike fit
Band Booster IELTS is a private online tutor, not a test centre, not the exam board and not an admissions adviser. It does not register you for the test, set exam fees or dates, say what any institution accepts, or give visa or immigration advice, and it is not affiliated with any institution on this page, which appears only as the source of a rule. Mike, a Cambridge CELTA-certified teacher based in Hanoi who scored 8.5 in IELTS Speaking, teaches every session himself, one-to-one and live on Google Meet in English. See About Mike.
A session can concentrate on one skill, such as Speaking in the real three-part format, or on Writing (Task 1 and Task 2, marked against the public band descriptors), Listening or Reading, or cover all four, with feedback during the session. The booking page shows your price in your own currency before you pay, and a paid 30-minute trial is available once per student, on a first booking. There is no subscription, rescheduling is without charge up to 12 hours before the slot, and no band is promised: progress depends on your starting point and the work you do between sessions.
