This chapter deals with the continuous professional development required in the teaching profession with a focus on the European Union, embracing the education sector as a whole socio-anthropological structure with similar needs and expectations. In particular, the topic of professional networking and mobilities, analyzed under the effect of the Erasmus Plus program, emphasizes the need for a new perspective. Social network analysis improves the understanding of particular behavioral patterns promoted by the implementation of European education policies in public education networking. The chapter contributes to policymakers in the field of education and training in the education sector.
