The TOEFL (Test of English as a Foreign Language) is a standardized test that measures the English language proficiency of non-native speakers. It is widely used for university admissions, work visas, and immigration purposes. The test assesses skills in reading, listening, speaking, and writing, providing a score that indicates how well a person can communicate in academic or professional settings in English-speaking countries. The TOEFL is available in both internet-based (iBT) and paper-based formats, with the iBT being the more common option.
