The Test Of English as a Foreign Language (or TOEFL , pronounced “toe-full”) evaluates 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 US and other English-speaking colleges and universities. The TOEFL is the product of the Educational Testing Service (ETS), which is contracted by the private, non-profit firm, the College Board to administer the test in institutions in the US; they also produce the SAT.
The test is usually taken on a computer in a test center, although paper versions are available where it is not possible to take it this way. TOEFL is administered worldwide.
The Computer Based Test for TOEFL called the CBT , is an adaptive test; meaning that your next question’s difficulty level depends on the correctness of your response to the current question. This helps TOEFL to grade the person’s knowledge on the English language; by assuming him/her to be of an average capability at the beginning of the test, and with the responses received at the every question the program decides to give you a tougher or easier question based on whether your question was answered correctly or not. The CBT follows computer adaptive test strategy for the Listening and Structure section alone. The reading comprehension and Essay writing are not computer adaptive.
The test consists of four sections :
Structure and Written Expression
Reading, Comprehension and Vocabulary
