You may need the IELTS General Training test to migrate to countries such as Australia, Canada, New Zealand and the UK.
The band score you need to migrate to a particular country varies. Check our Who accepts IELTS page to check what band score you need.
If you plan to migrate to Canada, Australia, New Zealand, the UK or the USA, taking an IELTS General Training test makes sense. Or if you plan on studying in secondary education, or enrolling in vocational training, this might still be the right choice.
But if you plan to study in higher education or want professional registration in an English-speaking country, you might need to take an IELTS Academic test.
