University English requirements

What Duolingo score do you need for Lehigh University?

Lehigh's graduate colleges set a Duolingo English Test minimum of 125 in Arts and Sciences, Business, Health and Engineering, and 120 in Education, with section minimums in Education and Engineering. Undergraduate admission prefers TOEFL or IELTS and considers Duolingo when those are not available; it says 120 or higher indicates strong English and 110 to 119 may suggest a need for support.

How Lehigh handles Duolingo scores

Undergraduates: Lehigh prefers TOEFL and IELTS and considers the Duolingo English Test or TOEFL iBT Home Edition if those exams are not available to you. Scores must come directly from the testing agency, and SAT or ACT results cannot meet the English requirement.

Graduate applicants: for unconditional admission you must meet every section minimum and the overall minimum for your college. Unofficial score reports (an uploaded copy, not self-reported scores) are used for the first review, but official scores must come from the testing agency once an offer is made. Duolingo scores are valid for two years from the test date and must still be valid when your I-20 is issued.

Teaching assistants: doctoral and research master's students appointed as TAs may need an extra English assessment through Lehigh's International Center for Academic & Professional English before teaching, even if they are exempt from a test for admission.

For comparison, the graduate page sets IELTS at 6.5 overall in most colleges and 7.0 in Business, and the undergraduate page gives IELTS 7.5+ as its strong-proficiency guide.

If your Duolingo score is below Lehigh's level

The graduate page says applicants who do not meet the minimums may be considered for admission with conditional English enhancement training required. The undergraduate page gives no conditional route; it describes scores below 110 as raising considerable concern about readiness.

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