If you plan to study in higher education or seek professional registration, you can take an IELTS Academic. Or if you want to study in secondary education, work or migrate to an English-speaking country, IELTS General Training might be right for you.
Where you want to study, work or migrate to will affect which test you need to take.
Make sure you visit the relevant government or institutional websites to confirm which test you need to take, as government agencies, institutions and other recognising organisations set their own IELTS entry requirements.
IELTS Academic and General Training are two wholly separate types of test, for two different purposes. While some individual organisations may accept an Academic result in the place of General Training, this decision is up to them. You will need to contact your specific organisation to learn more.
