The IELTS test assesses your abilities in all four skills - listening, reading, writing and speaking - in less than three hours.
The IELTS test format is tried and trusted by organizations and test takers worldwide, and has not changed significantly for over 20 years.
You will take the Listening, Reading and Writing tests all on the same day one after the other, with no breaks in between them. They are always taken in this order. Your Speaking test will either be after a break on the same day as the other three tests, or up to seven days before or after that. This will depend on your test centre.
