What Duolingo score do you need for Purdue University Fort Wayne?

The requirements page says results are only valid for two years from the exam or award date, at both levels. The graduate Duolingo level is the only one with subscores, so a 115 overall with one subscore below 115 does not meet it.

The page does not give a Duolingo-specific sending instruction or a separate level for graduate assistantships.

Compared with IELTS: undergraduates need IELTS 6.5 or Duolingo 110. Graduate applicants need IELTS 6.5 with bands of 6.5 reading, 6.0 listening, 6.0 speaking and 5.5 writing, or Duolingo 115 in every subscore.

The graduate section lists completion of ELS Level 112 as another way to show English proficiency. The page does not describe a conditional admission route based on a lower Duolingo score, and says US high school or university English courses taken as ESL do not qualify for undergraduates.

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