The usual languages for work (classes, notes, bibliography, etc.) are Catalan and Spanish, indifferently, in line with the preferences of each professor and the availability of the subjects given. The faculty will also be able to use materials in English and French and teach classes in these languages, if necessary. Students can complete course work in Catalan, Spanish or English.

The courses and seminars may be adapted to the language in which they are taught, depending on the composition of the group and its level of internationalization.
