Language requirements depend on the language in which the program is taught. If the program is taught in the local language, students must show proficiency in that language. For example, programs taught in German, Norwegian, or Finnish usually require language proficiency at the B2 or C1 level. For programs taught in English, universities usually accept English test scores such as IELTS, TOEFL, or PTE Academic. The required scores may vary depending on the university and the program. It is important for students to prepare for these language tests well before applying.
