IELTS is the International English Language Testing System. It is prepared by the University of Cambridge ESOL Examinations together with its partners, including the British Council.
The IELTS has two versions; the General Training (GT) module is for those who need an English language qualification for their work, because they are moving to an English-speaking country or because they want to measure their general English ability. Many governments and professional organizations require some of their workers to have the IELTS. The GT module tests your ability to use English in different social situations, and because this module is suitable for people wanting to do secondary education in an English-speaking country, there is also an educational part, but less than in the academic module. Overall, more than 1,500 organizations accept or require an IELTS qualification.
The Academic module is often used to check whether a student is ready to study in a university where the teaching is in English. Universities in many countries accept IELTS as an English Language qualification, and even some universities in the USA now accept it instead, or as well as, the TOEFL test.
IELTS is becoming more and more popular. Millions of people take the test every year. There are more than 400 test centres in 120 countries, and the number is increasing all the time. The test centres are run by either the IELTS organizations or by the British Council. Your nearest British Council will be able to tell you where to take the test. Make sure that they know which module you want to take.
