IELTS, or International English Language Testing System, is a proficiency test for individuals aiming to study or work abroad, accepted by over 6000 institutions globally. It offers two modules—Academic for university admission and General for immigration or work visas—each comprising specific test formats for listening, reading, writing, and speaking. With tests conducted multiple times a year and a validity of two years, obtaining a minimum band score of 6.5 is often necessary for admission or immigration purposes.
