What Duolingo score do you need for North Dakota State University?

The undergraduate page says all test scores are valid for two years and must be sent directly to NDSU. At graduate level, the Graduate School page says official Duolingo scores must be sent electronically to "North Dakota State University - Graduate", and the test date must be within two years of your application.

Duolingo is accepted for graduate teaching assistant roles. The catalog says GTAs must meet test score minimums under North Dakota state law; you need to meet the minimums of only one test, and you may retake and submit new scores at any time.

For comparison, the undergraduate page and the graduate policies both set IELTS at 6.0 overall.

Neither admission page describes conditional admission tied to a Duolingo score. For teaching roles, graduate students below the GTA minimums may still qualify as a grader or in-class GTA by completing LANG 701, LANG 702 and a mock teaching exam set with their department.

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