What TOEFL score do you need for Jacksonville State University?

The page lists the TOEFL iBT, IELTS, PTE, iTEP and Duolingo as accepted tests. For undergraduates it gives the TOEFL figure on both scales by test date; for graduates it gives 79 only.

For comparison, the same page sets IELTS at 5.5 for undergraduates and 6.0 for graduates.

Completing the English Language Institute (ELI) at Level 4 meets the undergraduate requirement and Level 6 the graduate one. Students from the listed English-speaking countries are exempt from the test. Transfers bringing at least 24 academic credit hours from accredited US institutions may be exempt (by request to international admissions), as may graduate applicants with a bachelor's degree from an accredited US institution.

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