What PTE score do you need for the University of Houston?

Graduate scores must be valid and reportable at the time you submit your application and are generally valid for two years from the test date. The page asks for official scores but does not give a PTE sending method, and it does not mention PTE Academic Online or PTE Core.

On the same page, IELTS Academic needs 6.5 overall, TOEFL 79 (or 4 on the 6-point scale) and Duolingo 105.

Graduate applicants can also meet the requirement by completing Level 6 of the Intensive English Program at UH's Language and Culture Center, or with a degree from a US institution or a listed English-speaking country.

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