The Test of English as a Foreign Language (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.

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.The TOEFL test is offered in different formats depending on your location.
