What IELTS score do you need for TU Delft?

All TU Delft MSc programmes are taught in English, and its MSc admission requirements for international degrees accept only TOEFL iBT, IELTS Academic (including UKVI Academic) and Cambridge C1/C2. The page says TU Delft does not deviate from these scores.

TOEFL MyBest scores are not accepted and all TOEFL scores must come from a single test. TU Delft does accept IELTS One Skill Retake. The test date must be no older than two years on the day you submit your application, and TU Delft verifies scores using your IELTS TRF number.

For the MSc, TU Delft accepts the TOEFL iBT Special Home Edition or IELTS Online (Academic) only if test centres are temporarily closed or it is unsafe or impossible to travel. The BSc page does not mention online tests.

MSc applicants are exempt if they are nationals of Australia, Canada, Ireland, New Zealand, the UK or the USA, or hold a bachelor's degree from one of those countries. A degree from an overseas branch campus of a university from those countries does not count.

On the BSc page, TU Delft tells nationals of the People's Republic of China that they need a Nuffic certificate for visa purposes, which requires IELTS or TOEFL iBT. For everyone else, see IELTS for the Netherlands.

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