Test of English as a Foreign Language (TOEFL /ˈtoʊfəl/ TOH-fəl) 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.

The world’s premier English-language test for university study, work and immigration. Accepted by more than 11,000 universities in over 150 countries, the TOEFL iBT^® test helps students stand out confidently in English and show they have what it takes to succeed.

TOEFL evaluates the English language skills of people with a native language other than English.
If you wish to undertake university studies or to work in the United States, you will be asked your TOEFL score. In fact, the majority of colleges and universities in the United States and in English-speaking Canada use the TOEFL results in their admission procedure for foreign students. What’s more, a number of large international companies use TOEFL when recruiting employees with a native language other than English.

Unlike the different Cambridge exams, the American exams are  “thermometer” tests that instantly measure your level of English. There is no prerequisite level required to pass the TOEFL.
However, a period of preparation may be useful or even essential to obtain a good score for the TOEFL.

Numerous course options – varying in intensity and duration – are available to you to prepare for the TOEFL according to your objectives (that is, the score you need to obtain).

Structured in the form of multiple-choice questions, the TOEFL is administered by computer (Computer-Based Test: CBT) and on paper (Paper-Based Test) in Europe. The TOEFL CBT lasts approximately four and a half hours. The Paper-Based Test lasts about three and a half hours. They are both composed of four sections that evaluate all aspects of the language.

Listening:
This first section of the TOEFL measures your aptitude for understanding English as it is spoken in North America with everyday vocabulary, expressions and grammar.

Structure:
This second section of the TOEFL measures your aptitude in recognising the appropriate language for general written English.

Reading:
The third section of the TOEFL measures your ability to understand non-specialised texts.

Writing: (= TWE – Test of Written English)
The final section of the TOEFL measures your ability to write a text in English on a specific subject. You must be able to generate, organise and support ideas using common written English in an essay format. For the TOEFL CBT, so as not to disadvantage candidates who are not familiar with the American keyboard QWERTY, you can choose either to write the essay by hand or to type it on a computer.
