The Test of English as a Foreign Language (TOEFL) measures English proficiency of non-native speakers of English. The TOEFL focuses on North American English as it is used in a university or college setting. It is specifically designed to evaluate English ability in international students who wish to study in English at North American colleges and universities.

The TOEFL is different from the TOEIC (Test of English for International Communication). The TOEFL tests academic English, while the TOEIC tests everyday English used in business. The TOEFL measures intermediate to fluent English language ability, while the TOEIC measures a wider range, from beginning to advanced English ability.

The TOEFL is written and scored by the Educational Testing Service (ETS), a private, not-for-profit company based in Princeton, New Jersey, in the U.S. More than 2400 colleges and universities in the U.S. require international applicants for admission to take the TOEFL.
