'IELTS for UKVI' is a UK government approved Secure English Language Test (SELT). This means that IELTS can be used to prove your English language abilities in support of a UK Visa and Immigration (UKVI) application.
The IELTS test for UK visa purposes is designed to meet certain administrative requirements that are only specified by UK Visas and Immigration. Test Report Forms will be slightly different, to show that test takers have taken the test at an IELTS UK visa session. The actual test taken is the same – same content, examiners, format, level of difficulty, scoring and so on.
Both the UKVI and Life Skills tests must be taken at an IELTS test location specifically authorised by UKVI, and must be taken under specified conditions. You will receive an IELTS or IELTS Life Skills Test Report Form to show that your test met these requirements.
