The International English Language Testing System, or IELTS, is an international standardised test of English language proficiency for non-native English language speakers. It was established in 1989 and is jointly managed and organized by the British Council, IDP: IELTS Australia and Cambridge English Language Assessment. IELTS is one of the major English-language tests in the world. IELTS is the only Secure English Language Test approved by UK Visas and Immigration (UKVI) for visa customers applying both outside and inside the UK. It is also a requirement for immigration to Australia and New Zealand.
There are two versions of the IELTS:
General Training Version
IELTS Academic is intended for those who want to enroll in universities and other institutions of higher education and for professionals such as medical doctors and nurses who want to study or practice in an English-speaking country.
IELTS General Training is intended for those planning to undertake non-academic training or to gain work experience, or for immigration purposes.
Both the versions are valid for a period of two years.
