IELTS may be a requirement for entering your desired course in an educational institution. It is also used in many countries as a part of their migration assessment. If you are not sure as to why you might need to sit the IELTS test or about the score you need, contact the organisation you are applying to.

They will be able to provide further information, including whether native speakers need to complete the IELTS test. Even if English is your primary language, you will still need to prepare for the test.
