What Duolingo score do you need for KMUTT?

Applicants whose native language is not English must provide evidence no more than two years old until the date of application. You are exempt if you are a native speaker or national of a country where English is the official language, hold a qualification from such a country, or studied a previous course in English or in an English-speaking country. The page says some courses may set higher requirements and suggests contacting the faculty or school directly. It gives no Duolingo sending instruction.

For comparison, the same page sets IELTS at 5.0 or above for every programme in the table.

The School of Architecture and Design describes a route for lower scores: applicants with IELTS 4.5, TOEFL iBT 53 to 60, CU-TEP 53 to 60, RMIT Intermediate, TOEIC 540 to 604 or CEFR B1 can apply, sit the aptitude test and interview, and if accepted take an English course in May and June. The page gives no Duolingo figure for that route, so ask the school before relying on it.

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