‘IELTS for UKVI’ is a UK government approved Secure English Language Test (SELT). This means that UKVI IELTS can be used to prove your English language abilities in support of a UK Visa and Immigration (UKVI) application. This applies to everyone coming from a non-English speaking country. IELTS is accepted in Australia, Canada, New Zealand, and the UK. But UKVI is only accepted in the UK itself.
The Occupational English Test is an English language test for healthcare professionals recognised by various regulatory healthcare bodies. It assesses the language communication skills of healthcare professionals who wish to register and practise in an English-speaking environment.
