While English language is given priority as it is the medium of instruction at the university, the Department conducts basic Sinhala and basic Tamil courses for all KDU students in order to give them an exposure to these national languages.
All foreign students studying at the university are required to follow national languages courses. Students whose native language is Sinhalese are required to follow the Tamil course and the students whose native language is Tamil have to follow the Sinhala language course.
