IELTS has two versions – Academic and General Training. The Academic test is for those who want to study at a tertiary level in an English-speaking country. The General Training test is for those who want to pursue work experience or training programs, secondary school or migrate to an English-speaking country. All candidates take the same Listening and Speaking tests but different Reading and Writing tests.
Contact the organization or institution to which you are applying to find out what it requires. Note that you must know which version to take when you complete the online application process.
