What TOEFL score do you need for Northern Arizona University?

NAU's school code is 4006, and undergraduate admissions accepts MyBest scores. Graduate test scores must come from a test taken within two years of the term you plan to start, and NAU will not evaluate a graduate application until it receives valid scores. Not every department accepts every test type.

TOEFL iBT score reports from January 2026 also carry a 1 to 6 band score; our guide to the new TOEFL score scale explains how the two scales appear on a report.

For comparison, the undergraduate page asks for IELTS 6, and the graduate page asks for IELTS 6.5.

Undergraduates who do not meet the requirement may need to take an English placement test on arrival or enrol in the Program in Intensive English (PIE) until they reach the required level. Graduate applicants below the level may also be eligible for PIE.

Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your NAU programme page and in your offer letter, so check it there before you book a test.
