Certifying a minority language: a first description of the Sardinian case

The paper presents the results of the University of Cagliari project aimed at creating the first linguistic certification of the Sardinian language (level C1). The paper describes the theoretical assumptions, work phases, critical issues, and the choices that led to the development of the proposal, as well as the structure of the examination. In the specific case of a non-standardized language with remarkable geographical variation, such as Sardinian, it will be shown how the linguistic certification process also represents a fundamental moment for rethinking and promoting linguistic learning and teacher training.
