The TOEFL, formally known as Test Of English as a Foreign Language, is a test of an individual's ability to use and understand English in an academic setting. The test is designed and administered by Educational Testing Service (ETS), and TOEFL is a registered trademark of ETS.

It was developed to address the problem of ensuring English language proficiency for non-native speakers wishing to study at U.S. universities. It has become an admission requirement for non-native English speakers at many English-speaking colleges and universities. Additionally, institutions such as government agencies, licensing bodies, businesses, or scholarship programs may require this test. A TOEFL score is valid for two years and then will no longer be officially reported
