The IELTS UKVI test 

What is IELTS for UK Visas and Immigration (UKVI)?

If you are intending to work or study in the UK, you may need to apply for a UK Visa and demonstrate that you have met the required level of English by taking a Home Office approved Secure English Language Test (SELT), such as IELTS for UKVI (Academic and General Training) or IELTS Life Skills.

Is there a difference in test format between IELTS and IELTS for UKVI?

IELTS and IELTS for UKVI are the same in terms of format, content, scoring and level of difficulty. However, the Test Report Form which contains your results is slightly different to show that you have taken the test at an official IELTS for UKVI location, which is approved by the UK Home Office.
