The IELTS (International English Language Testing System) is a standardized test designed to assess the English language proficiency of non-native speakers. It evaluates four key skills: listening, reading, writing, and speaking. The test is widely recognized by educational institutions, employers, and governments around the world. There are two main versions of the IELTS: the Academic module, for those seeking higher education, and the General Training module, for work or immigration purposes. Test scores range from 1 to 9, with higher scores indicating better language proficiency.
