The TOEFL probably top the list with regard to the sheer number of students across the world needing to undertake to demonstrate English language proficiency. The TOEFL test measures your ability to use and understand English at the university level and it evaluates how well you combine your listening, reading, speaking and writing skills to perform academic tasks.
The widest possible selection of universities and colleges accept TOEFL scores, including the top 100 in the UK, U.S, Canada, Australia and New Zealand. The TOEFL is held throughout the year. More than 9,000 colleges, agencies and other institutions in over 130 countries accept TOEFL scores.
The Reading and listening is the easiest to score. A computer will determine the number of points you receive, and then the score will be calculated on a scale of 0-30 for each section. At the same time the writing and speaking sections needs more involvement. Each response will be reviewed by at least two trained professionals and will independently give you a score from a scale of 0-4, which is then converted to the standardized 30 points scale. Score reports are available online about ten days after you take the test, and the official score reports your institution probably requires are mailed a little bit later, about 13 days after you take the test. So in all, it will be about three weeks after you take the test when your institution actually receives your score report.
