What Duolingo score do you need for Cal Poly Humboldt?

The proficiency page lists many other ways to meet the requirement, including ACT English 22, Level 6 at partner language centres, Cambridge exams and the DAAD Language Test. It does not state a Duolingo validity period, subscores or a teaching assistantship level.

Compared with IELTS: the same page pairs Duolingo 95 with IELTS 6.0 for undergraduates and Duolingo 110 with IELTS 6.5 for graduate study.

Humboldt's conditional admission page says undergraduate applicants who meet the academic requirements but lack English proficiency may be admitted to a partner language school with a conditional admission letter for their Humboldt programme. They study there until they meet the language requirement or reach an acceptable score, then apply formally. The page sets 15 April for fall and 15 October for spring. It does not describe a graduate route.

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