Cambridge English or IELTS for Studying Abroad? How to Choose
Hiroki Obara · DeveloperAlphaGeorgeHow-To
IELTS is jointly owned by the British Council, IDP IELTS and Cambridge University Press & Assessment (About IELTS). Cambridge University Press & Assessment also runs the Cambridge English Qualifications. So the Cambridge exams and IELTS are, in a sense, two tests from the same organisation.
They still work very differently. This post is for people choosing between them for study abroad: how they differ in practice, how to check what your university wants, and how to decide. Every figure was checked on the official sites on 3 November 2026. How the levels line up with IELTS bands and TOEFL scores through the CEFR is in Cambridge English Exams vs IELTS and TOEFL, so I won’t repeat the level tables here.
The main difference: choosing a level, or one test for everyone
One big difference is how results come out.
The Cambridge exams are split by level: A2 Key, B1 Preliminary, B2 First, C1 Advanced and C2 Proficiency. You choose which one to sit. Your result is a score on the Cambridge English Scale, and the certificate says whether you reached that level, did better than it, or fell one level short. How to read the score is in What Is the Cambridge English Scale?
With IELTS, everyone sits the same test. You get a band from 0 to 9 for each of the four skills and an overall band, which is their average rounded to the nearest half band (IELTS scoring in detail).
University requirements are often written in the form “IELTS 6.5 overall with at least 6.0 in each skill.” With IELTS, you compare your numbers with that line directly. Universities that accept Cambridge exams may also set scores, as in the Cambridge University example below, but you have to pick a level before you sit.
Format
IELTS comes in two versions: Academic, for undergraduate and postgraduate study, and General Training, for people migrating or studying below degree level. Listening and Speaking are the same in both; Reading and Writing differ (General Training). For a university application you normally need Academic.
| IELTS Academic | C1 Advanced | |
|---|---|---|
| Reading | 60 minutes | Reading and Use of English, 1 hour 30 minutes |
| Writing | 60 minutes | 1 hour 30 minutes |
| Listening | about 30 minutes | about 40 minutes |
| Speaking | 11 to 14 minutes, one to one with an examiner | 15 minutes, usually two candidates and two examiners |
| Total | 2 hours 45 minutes | about 4 hours |
Sources: IELTS Academic and C1 Advanced format.
The biggest difference in format is speaking. IELTS is an interview with an examiner. In a Cambridge exam you are paired with another candidate and part of the test is a discussion with them. Preparing for that is in The Cambridge English Speaking Test.
The Cambridge exams also have Use of English, which tests grammar and vocabulary directly and shares a paper with Reading. IELTS has no section that tests grammar or vocabulary on its own.
Recent changes to IELTS
In an announcement on 5 March 2026, IELTS said that from mid-2026 it would stop offering the paper-based test and deliver every test on computer, with timing varying by market. In selected markets, a “Writing on Paper” option lets you handwrite the Writing section. Paper-based results already issued are unaffected.
Computer-delivered IELTS offers One Skill Retake, which lets you resit just one of the four skills. It must be taken within 60 days of the original test, and only once per test (One Skill Retake). Whether a retake result is accepted is up to each receiving organisation, and the official page tells you to check with them before booking.
How long results take
| Results available | |
|---|---|
| IELTS on computer | mostly within 2 days |
| IELTS on paper | 13 days |
| Cambridge, digital | 5 to 10 working days after the exam |
| Cambridge, paper | normally 4 to 6 weeks after the exam |

Validity
Cambridge says its certificates do not expire, and that each organisation decides how old a result it will accept (results page).
IELTS recommends that results be treated as valid for two years from the test. For results older than that, it tells organisations to look for evidence that the person has kept up their English (Verifying IELTS results).
In practice, one view is that the difference is smaller than it looks. A Cambridge certificate may never expire, but if a university or a visa rule says “taken within the last two years,” that is the rule you follow. The University of Cambridge’s undergraduate page, for example, says an English test is only valid for visa purposes for two years from the exam date (entry requirements). A certificate without an expiry date can still help after the application: for jobs later on, or as a lasting record of your level.
How to check what you need
Here is one order to follow.
1. Read your university’s English language requirements page. Check:
- which tests it accepts, and whether that includes Cambridge exams or only IELTS and a few others
- the overall score and the minimum for each skill
- how recent the result must be, and whether that is counted at application or at the start of the course
- whether it accepts One Skill Retake results or tests taken online at home
At the University of Cambridge, for undergraduate entry, IELTS Academic normally needs 7.5 overall with usually 7.0 or above in each element. C1 Advanced needs 193 overall with no element below 185, together with other evidence of English. C2 Proficiency needs 200 overall with no element below 185.
2. Check the test providers’ search tools. IELTS has a search of organisations that accept IELTS, and Cambridge has a recognition search. The Cambridge page warns that recognition can change and tells you to contact the institution directly. These searches work as a starting point, with the final check on the university’s own page.
3. Check the visa rules. For the UK, some visa types require a Secure English Language Test (SELT) approved by the government, such as IELTS for UKVI (Academic), according to the Cambridge University page above. For student visas, universities can accept other English qualifications. The IELTS announcement above says the UKVI test is delivered digitally only. University requirements and visa requirements are separate, so check both.
Which should you take?
When in doubt, this is one order to think in.
What your university accepts. This decides most cases. Some universities list only a few tests, so if you are thinking of a Cambridge exam, check especially carefully.
When you need the result. If your deadline is close, or you think you may need to resit to reach your target, IELTS, with faster results and One Skill Retake, gives you more room to move.
Whether you know your level. If you are confident you are at C1 and your university accepts C1 Advanced, a Cambridge exam is a good choice, and you keep a certificate that doesn’t expire. If you aren’t sure of your level yet, IELTS, where you don’t have to choose a level in advance, costs you less if you misjudge. Choosing a Cambridge level is in Which Cambridge English Exam Should You Take?
The speaking format. One to one with an examiner, or a discussion with another candidate. That alone is not a reason to choose, but if everything else is equal, pick the one where you think you will do your best.

Building grammar and vocabulary with AlphaGeorge
AlphaGeorge, an app I make for iPhone and iPad, is for preparing for the Cambridge exams. It has a course of six levels from A1 to C2 with 66 units in total, and the levels from A2 to C2 match A2 Key through C2 Proficiency. A diagnostic test of about five minutes places you at a level to start. The app’s interface and explanations are in English and Japanese.
Each unit has lessons in grammar and reading, vocabulary, everyday conversation, writing and speaking. From the B2 units on, there are word formation and Key Word Transformation questions in the style of Cambridge Use of English. There are no tasks in the IELTS format, but grammar and vocabulary are the base for both exams. If you are taking IELTS, one way to split the work is to practise the format with the official sample tests and the grammar and vocabulary in the app.
AlphaGeorge is free to start, with ads and a limit of hearts. AlphaGeorge Premium, a monthly or yearly subscription, removes ads, makes hearts unlimited and lets you replay finished lessons. Keeping up daily practice is in AlphaGeorge Tips, and Getting Started with AlphaGeorge walks through the first session.
