NRP 56 “Language Diversity and Linguistic Competence in Switzerland“:
Swiss language policy aims on the one hand to strengthen the understanding between the various linguistic regions and on the other hand to foster both the formation of the identity of individuals and their mother-tongue and foreign-language skills. The National Research Programme “Language Diversity and Linguistic Competence in Switzerland“ (NRP 56) seeks to establish the scientific foundations for this policy.
