Test of English as a Foreign Language (TOEFL) is a Standardized test that evaluates the English Proficiency of people whose native language is not English. The TOEFL tests the ability to understand North American English. The TOEFL is developed and administered by the US-based "Educational Testing Service" (ETS). For the conduct of the test, ETS has appointed Testing Agencies in various countries, which act as franchisee for ETS. Computer based TOEFL is held all-round-the-year called iBT. The TOEFL® Internet-based test emphasizes integrated skills and measures all four language skills, including speaking, writing, reading and listening. The content on the test is authentic, and the language is consistent with that used in everyday, real academic settings. The number of questions and the time allocated to each question may vary. Therefore, one student may get 35 questions in Listening section while another may get 45. But, the additional questions are for research purposes only and the scores of all test takers are based on the same number of questions.
