The IELTS Academic test is made for students looking to study in an English-speaking environment or university, as it uses vocabulary common in academic settings. IELTS can also be used for professional registration.
The computer-based Pearson Test of English Academic (PTE) is designed for non-native English speakers looking to study abroad. Unlike other tests, you receive your results quicker, usually within 48 hours. Individuals can also use PTE for migration applications.
