The International English Language Testing System (IELTS) is an essential English language proficiency test required for education, employment, and visa applications in many English-speaking countries. Jointly administered by the British Council, IDP IELTS, and Cambridge English, IELTS evaluates a candidate's ability to communicate effectively in English. The test has two formats: IELTS Academic, aimed at students pursuing higher education, and IELTS General Training, designed for those moving to English-speaking countries for work or residency.

The exam consists of four modules: listening, reading, writing, and speaking, with a total duration of 2 hours and 45 minutes. The listening module lasts 30 minutes, the reading and writing modules each take 60 minutes, and the speaking module lasts between 11 to 14 minutes. Scores are awarded on a band scale from 0 to 9, with 9 indicating expert proficiency. In India, the IELTS exam fee ranges from approximately ₹17,000 to ₹18,000 (around $205 to $220 USD). Accepted in over 140 countries, IELTS is a key requirement for students aiming to study in countries like Canada, the UK, the US, and Australia.
