What Duolingo score do you need for Elon University?

Both pages tie the test requirement to the language of instruction at your school rather than your nationality: if you attend a school where English is not the primary language of instruction, you submit TOEFL, IELTS or Duolingo results.

Neither page states a Duolingo validity period or subscore rule.

For comparison, the undergraduate page and the graduate page both set IELTS at 6.5.

Neither page offers conditional admission or an English pathway for applicants below 110. The undergraduate page notes that SAT and ACT scores are optional for admission.

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