Some U.S. colleges and universities require or recommend that international applicants submit proof of their English language skills, usually in the form of a standardized test score.

Two of the more popular English language proficiency tests out there are the IELTS and the TOEFL.

Some schools prefer one test over the other, while others accept scores from either test – plus a few others. Prospective international students should make sure they research the preference of the schools they want to apply to.

If a school doesn’t have a preference, students should consider whether the TOEFL or the IELTS plays more to their strengths as they decide which to take.

TOEFL’s structure and language is more academically focused, test prep experts say, while the IELTS has a more real-world communication feel. However, this doesn’t mean the IELTS is easier, says Eliot Friesen, IELTS curriculum manager at test prep company Magoosh. “It’s still challenging, but it’s not that sort of in-depth academic material that you get on the TOEFL,” he says.

Another difference is that students take the IELTS on paper, while most test-takers face the TOEFL on a computer. According to the TOEFL website, 97 percent of people who take the TOEFL take the iBT, or internet-based test, as opposed to the paper version.

Students with strong typing skills may find the TOEFL to be a better fit, while those who prefer hand writing their responses might lean toward the IELTS.

Prospective international students can use the table below to compare and contrast the IELTS Academic test – the version of the IELTS meant for those applying to colleges and universities – and the TOEFL iBT test. The average minimum scores information comes from U.S. News Best Colleges data.
