This paper focuses on an urgent educational challenge of the contemporary age: the form-action of digital citizenship. Starting from the European reference framework for citizens' digital skills, the author develops a reflection based on the interconnection between digital skills and Capability Approach. The latter, developing an ethical-economic-political sense horizon based on: "functioning", "capability" and "agency", completes and directs the theoretical-methodological framework dictated by normative requirements on the development of digital skills. The reflection built can be an opportunity to direct the training action, in order to promote the development of digital skills, towards full freedom and the enhancement of the critical awareness of citizens in making choices for the achievement of desirable educational-professional standards.
