The TOEFL (Test of English as a Foreign Language) is written, developed and administered by the Educational Testing Service (ETS), a private, non-profit organization based in Princeton, New Jersey. The TOEFL test measures the ability of nonnative speakers of English to use and understand North American English as it is spoken, written and heard in college and university settings.
Currently more than 2,400 colleges and universities in the United States and Canada require the TOEFL test scores from non-English speaking students in order to admit them to a program. TOEFL is also used by academic institutions in other countries where English is the language of instruction. In addition, government agencies, scholarship programs, and licensing/certification agencies use TOEFL scores to evaluate English proficiency.
