Test of English as a Foreign Language (TOEFL) is a standardized test of English language proficiency for non-native English language speakers wishing to enroll in US universities. The test is accepted by many English-speaking academic and professional institutions. TOEFL is one of the two major English-language tests in the world, the other being the IELTS.
TOEFL is a trademark of the Educational Testing Service (ETS), a private non-profit organization, which designs and administers the tests. The scores are valid for 2 years; then they are no longer reported.
Since its introduction in late 2005, the TOEFL Internet-based Test (iBT) format has progressively replaced the computer-based tests (CBT) and paper-based tests (PBT), although paper-based testing is still used in select areas. The TOEFL iBT test has been introduced in phases, with the United States, Canada, France, Germany, and Italy in 2005 and the rest of the world in 2006, with test centers added regularly. The CBT was discontinued in September 2006 and these scores are no longer valid.
Initially, the demand for test seats was higher than availability, and candidates had to wait for months. It is now possible to take the test within one to four weeks in most countries. The four-hour test consists of four sections, each measuring one of the basic language skills (while some tasks require integrating multiple skills), and all tasks focus on language used in an academic, higher-education environment. Note-taking is allowed during the TOEFL iBT test. The test cannot be taken more than once every 12 days.
