What PTE score do you need for Salem State University?

The page does not mention PTE Academic Online or PTE Core, a validity period or a Pearson code. It says the admissions office reserves the right to ask for more proof of English, and that sub-scores are also considered in judging whether your English is strong enough.

IELTS on the same page is 6.0, so PTE 49 is the PTE route to the IELTS 6.0 level. TOEFL iBT is 71 and Duolingo 110.

The page accepts completion of core level 5 or higher at the American Language and Culture Institute at Salem State, with a score of 49 on the Pearson Progress Test (GSE 35 to 50) and a letter from the programme director. That is a separate Pearson test, not PTE Academic. SAT Evidence-Based Reading and Writing of 470, a B in a US first-year English composition course, an IB diploma, or schooling in an English-speaking country also exempt you.

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