You have to meet the Norwegian language requirements, or have a Scandinavian language as your mother tongue, if you want to apply to any of NTNU's degree programmes. You also must meet the basic requirement for admission, and demonstrate that you meet the English language requirements.
NTNU offers Norwegian courses that meet the Norwegian language requirements.
The application deadline for the programme is March 1st for students with an international degree, and April 15th for Norwegian and Nordic degree students. Students apply through Samordna Opptak.
