The IELTS Academic test is for people applying for higher education or professional registration in an English speaking environment. It reflects some of the features of academic language and assesses whether you are ready to begin studying or training. This approach is widely supported by the institutions that recognise IELTS.
The IELTS General Training test is for those who are going to English speaking countries for secondary education, work experience or training programs. It is also a requirement for migration to Australia, Canada, New Zealand and the UK. The test focuses on basic survival skills in broad social and workplace contexts.
