The Test of English as a Foreign LanguageTM (TOEFL) measures the ability of nonnative speakers of English to use and understand English as it is spoken, written, and heard in college and university settings. The TOEFL tests all four language skills that are important for effective communication: Speaking, Listening, Reading, and Writing. The test helps students demonstrate that they have the English skills needed for success. TOEFL also emphasizes integrated skills and provides better information to institutions about students' ability to communicate in an academic setting and their readiness for academic coursework. TOEFL will be needed for Education in Canada.
The TOEFL test is developed and administered by the US-based "Educational Testing Service" (ETS). This implies that ETS sets the questions, conducts the test, and sends each examinee the score report. For the conduct of the test, ETS has appointed Testing Agencies in various countries, which act as franchisee for ETS. In India, this agency is the "Prometric Testing Services Private Limites" which administers the test at various centers across India.
Computer based TOEFL test is held all-round-the-year. Unlike other exams, you can choose your own date and time for taking the TOEFL test. September to December is the high season for TOEFL test, so in case you intend to take the test during this period, you need to register very early (say 90 days in advance) to get a date of your choice. Otherwise, registering at least three days in advance is mandatory. The test lasts roughly four hours.
