The Test of English as a Foreign Language (TOEFL) is a standardized test measuring English language proficiency for non-native speakers, primarily used for university admissions in English-speaking countries. It evaluates reading, listening, speaking, and writing skills, with each section scored out of 30 for a total score range of 0-120. The TOEFL is available in two formats: TOEFL iBT (Internet-based Test) and TOEFL PBT (Paper-based Test), though iBT is more common. Preparation resources include official guides, practice tests, and prep courses. The test can be taken at authorized test centers, and scores are usually available within 6-10 days. Registration is online through the official TOEFL website.
