If you want to study in the UK or apply for professional registration, you might need to take an IELTS Academic for UKVI test. It is a Secure English Language test (SELT) approved by the UK home office for visa applications to the United Kingdom.
The Academic for UKVI test is the same as the Academic test in terms of content, format, scoring and the level of difficulty. However, the UKVI test is only available at test centres who meet the administrative requirements outlined by the UK Home Office, currently only Taipei provides the UKVI test in Taiwan. Your Test Report Form (TRF) will also look slightly different if you take a UKVI IELTS test.
IELTS and IELTS for UKVI are the exact same test in terms of format, content, scoring and level of difficulty. The only difference is an IELTS for UKVI test is approved by the UK Home Office for work, study and migration purposes.
If you take an IELTS for UKVI test, your test report form will be a little different to show you have taken an IELTS for UKVI test at an approved test centre.
