What TOEFL score do you need for Marshall University?

All applicants, whatever their citizenship, must show English proficiency unless they meet an exemption. The page gives the new-test minimums on both scales, so you can meet the level with either figure on your report. It states no section minimums or institution code.

For comparison, the page sets IELTS Academic at 6.0 for undergraduates and 6.5 for graduates.

Exemptions include successful completion of an approved ESL programme, one year of full-time study at an accredited US university (24 undergraduate or 18 graduate credit hours), ENG 101 transfer credit with a C or better, or a degree from an approved English-speaking country. Undergraduates can also qualify through a year at a US high school with a C or higher in English, or IGCSE, O-Level or IB English results.

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.
