The IELTS test was introduced in 1989 to assess "whether candidates are ready to train in the medium of English". It is now used for this purpose around the globe. Depending on the course of study that students plan to take, students must elect to sit either the Academic IELTS test or the General Training IELTS test. This choice must be made when applying to sit the test. The Academic IELTS test is necessary for students who plan to study at university (undergraduate or postgraduate courses), and will test the student's ability both to understand and to use complex academic language. The General Training IELTS test is required by other institutions, such as colleges and high schools, for courses that require less complex language skills, and is also as a general test of English proficiency e.g. for immigration purposes in Australia, Canada and New Zealand etc.
