What TOEFL score do you need for Mount Allison University?

The page lists Mount Allison's TOEFL DI code as 0939 and says you must provide proof of English if asked. It notes that meeting the minimum English requirement does not guarantee admission. It gives no rule on score validity, MyBest or the Home Edition.

For comparison, the same page asks IELTS Academic 6.5 with no band score lower than 6.

Mount Allison may offer conditional admission and let you enrol in its English Pathway Program, a language, academic and cultural immersion programme offered online in summer and autumn; completing it brings unconditional admission if you meet the academic requirements. You can also complete university-preparatory English at a partner school such as CLLC, ECLC, ILI, Kaplan, McKenzie College or SACLI, or retake TOEFL and send improved results.

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