The International English Language Testing System (IELTS) is an internationally standardized test of English proficiency for non-native English speakers. It is jointly administered by the British Parliament, IDP, and Cambridge English, and was established in 1989. IELTS is one of the world's leading English language tests. The IELTS test has two modules: Academic and General Training. In 2023, IELTS introduced a skills replay feature for computer-delivered testing, allowing test takers to replay any section of the test (Listening, Reading, Writing, and Speaking).
