Can I apply to a Dutch taught bachelor’s programme without knowledge of the Dutch language?

Yes, you can. The University offers intensive Dutch language courses for students with an international education who must first learn Dutch. The language training usually takes an entire year in practice.
You’ll need a good command of the Dutch language to follow the lectures, tutorials, exams and reading materials. Proof of English proficiency is also required, as some of your study materials and lectures may be in English.
Note that Leiden University also offers bachelor’s programmes in English.
