TOEFL (Test of English as a Foreign Language)
TOEFL is a standardized test to measure the English language ability of non-native speakers wishing to enroll in English-speaking universities. The test is accepted by many English-speaking academic and professional institutions. TOEFL is one of the two major English-language tests in the world.
TOEFL is a trademark of the Educational Testing Service (ETS), a private non-profit organization, which designs and administers the tests. ETS issues official score reports, sent independently to institutions, for two years following the test.
