The International English Language Testing System (IELTS) is a globally recognized standardized test that measures English language proficiency for non-native speakers. It is commonly required for admission to universities, immigration, and professional registration in English-speaking countries such as the UK, Australia, Canada, and New Zealand. The test assesses four key skills: Listening, Reading, Writing, and Speaking, and scores each on a band scale from 1 (non-user) to 9 (expert user)
