IELTS test is to assess your abilities in all four skills – Listening, Reading, Writing, Speaking, in less than three hours.
The IELTS test format is strived 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 center.
