Choosing the right English language test is one of the most important steps when planning to study abroad. Many universities, scholarship programs, and immigration authorities require proof of English proficiency before accepting international applicants.
The three most popular English language tests are the Duolingo English Test (DET), IELTS, and TOEFL iBT. Each test measures your English skills, but they differ in format, cost, duration, acceptance, and testing experience.
If you're unsure which exam is best for your study or visa goals, this guide will help you compare all three tests and make an informed decision. See also our complete visa guidance and scholarships without IELTS guide.
