Most university degrees in France include languages as part of the curriculum. LANguages for Students of Other Disciplines (LANSOD) courses refer to language courses destined to students whose major is not languages, but another discipline such as musicology or chemistry. It is estimated about 90% of students enrolled in French higher education attend LANSOD classes. At the same time, it is agreed that French universities should 'professionalise' students -- that is, prepare them for their future professional lives. This chapter aims at questioning the notion of professionalisation in the specific context of LANSOD university courses in France. To do so, the author will first investigate how 'professionalisation' is commonly defined and how it is implemented in French universities, especially in LANSOD courses. The second part of this article will deal with the particular case of a LANSOD undergraduate course at the University of Lille; the point is to illustrate how complex it can be to design a curriculum relevant to learners' future professional needs and to provide practitioners with tools that could prove useful in similar contexts for the design of professionalising LANSOD courses.
