The Test Of English as a Foreign Language evalutes the potential success of an individual to use and understand standard American English at a college level. It is required for non-native applicants at many American and English speaking colleges and universities. The TOEFL is a product of Educational Testing Service (ETS). The test consists of four sections: Listening Comprehension, Structure, Reading Comprehension and Vocabulary, and Essay Writing. Usually, the undergraduate schools demand 213/300(computer based test) and the graduate schools more.
