Cambridge C1 Advanced (formerly known as CAE) is a well-established English proficiency exam that’s genuinely different from IELTS and TOEFL in one significant way — it doesn’t officially expire — but that doesn’t automatically make it the right choice for your applications.
Acceptance varies by university and program and is reviewed periodically — confirm whether your specific target universities accept C1 Advanced directly on their admissions pages before booking.
How it’s scored
C1 Advanced uses the Cambridge English Scale, running from roughly 142 to 210, testing the same four skills as IELTS and TOEFL (reading, writing, listening, speaking). A qualifying result typically lands you a C1 level certification, with sufficiently high scores earning a C2 level result instead — meaning you can actually score higher than the exam’s nominal target level, which doesn’t have a direct equivalent in IELTS or TOEFL’s scoring structures.
The genuine advantage: no official expiry
Unlike IELTS and TOEFL, which most universities only accept if taken within the last two years, a Cambridge English qualification is intended as a permanent record of your level at the time you took it. In practice, many universities still prefer a recent result regardless of the certificate’s official validity, so this advantage matters less for a first-time applicant than it does for someone who took the exam years ago and doesn’t want to retake it.
The real limitation: acceptance is less universal
This is the important trade-off: C1 Advanced is very widely accepted by UK universities, reflecting its Cambridge origins, but it’s accepted by a noticeably smaller number of US, Canadian, and Australian institutions compared to IELTS or TOEFL, which are near-universal. If your applications are UK-focused, this is a genuinely strong option. If you’re applying broadly across multiple countries, confirm acceptance at every single target university individually before committing — this is not a test to default into without checking.
Format and cost
The exam covers Reading and Use of English, Writing, Listening, and Speaking, offered in both paper-based and computer-based formats, with cost generally comparable to IELTS and TOEFL. The Speaking test is done face-to-face or via video call with an examiner, similar in format to IELTS.
Who should actually consider it
If you’re applying primarily to UK universities, already have strong general English preparation, and like the idea of a certificate that doesn’t expire, C1 Advanced is a legitimate choice worth comparing against IELTS. If your target list spans the US, Canada, or Australia alongside the UK, IELTS or TOEFL remains the safer default given their broader, more consistent acceptance.
Deciding between English tests
See IELTS vs TOEFL vs Duolingo and PTE Academic for how the other major options compare, and confirm your full target university list’s accepted tests before booking any exam — this is a decision worth making once, deliberately, rather than defaulting to whichever test is most talked about.
