What Duolingo score do you need for Marshall University?

Marshall says all applicants, regardless of citizenship, must provide proof of English proficiency, and lists exemptions such as a degree from an approved English-speaking country, one year of full-time study at an accredited US university, or transfer credit equivalent to ENG 101 with a C or better. The page gives no validity period or sending instructions.

For comparison, the same page asks IELTS Academic 6.0 for undergraduates and 6.5 for graduate applicants.

The page does not describe conditional admission tied to a Duolingo score, but successful completion of an approved ESL programme is listed as an exemption for all applicants.

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