The IELTS, or the International English Language Testing System, is a widely used English language assessment test that assesses proficiency in English language skills. It is a popular exam for those who want to study or work in an English-speaking country. The IELTS is designed to assess four language skills: reading, writing, listening and speaking.

The IELTS is accepted by universities, employers, professional bodies and government agencies in many countries, including the United States, the United Kingdom, Canada, Australia, New Zealand and other English-speaking countries. It is also an official test for visa applications in the United Kingdom and Australia.
