IELTS was developed in 1989 and is now taken by over 3.5 million candidates annually. It is the world's leading test of English for academic and immigration purposes, widely preferred over TOEFL and PTE because of its universal acceptance — particularly for UK, Australian, and Canadian immigration, where IELTS is often the only accepted test.
The test is built on a core principle: proficiency must be demonstrated in real communicative contexts, not just through grammar tests. This is why Speaking involves a live conversation with a trained human examiner, and why Writing tasks require you to produce extended text rather than answer multiple choice questions.
