Should I take the Academic or General Training module?

You should speak to the institution that has requested an IELTS score from you and ask which test module they require, but as a guideline:

• The IELTS Academic test is suitable for those wanting to study in an English-speaking environment or university (higher education). You can also take IELTS Academic for professional registration purposes. The test measures if you are ready to begin studying in English. It features vocabulary that is familiar within an academic setting.
• The IELTS General Training test is suitable for those applying to study below degree level. This includes an English-speaking school or college. It can also be taken for work experience or other employment training. IELTS General Training is also required for migration to Australia, Canada, New Zealand and the UK. The test features everyday English language skills that you will need in social and workplace environments.
