The TOEFL, or Test of English as a Foreign Language, is a standardized test designed to measure the English language proficiency of non-native speakers. It is widely accepted by universities and colleges in English-speaking countries as part of their admission process. The test evaluates reading, writing, listening, and speaking skills to ensure that students can succeed in an academic environment. The TOEFL is administered by the Educational Testing Service (ETS) and can be taken in two formats: the internet-based test (iBT) and the paper-based test (PBT). The iBT is more common and includes integrated tasks that combine different language skills. Test scores are valid for two years and are used by institutions to assess a candidate's readiness for academic study.
