There are two types of the IELTS test: IELTS Academic and IELTS General Training. The IELTS academic is for the people who wish to apply for higher education and professional registration in an English speaking country. It reflects some features of the academic language and assesses whether you are ready to begin studying or training.
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. Listening and Speaking are the same for both tests, but the subject matter of the Reading and Writing sections differs depending on which test you take.
