IELTS (International English Language Testing System) and TOEFL (Test of English as a Foreign Language) are two of the most widely-accepted tests to certify your English proficiency. They both prepare students to pursue their academic goals in universities and higher learning institutions globally, where English is the medium of instruction. The main difference between IELTS and TOEFL is the countries from which they originate. IELTS is a UK-based exam, while TOEFL is an American-based one. Both assess non-native students’ ability to perform the four main components of Reading, Writing, Listening, and Speaking.
