This report is part of the ERASMUS+ ANGE project, which aims to develop innovation through the use of digital technology in the management of schools. More specifically, this work attempts to answer the question: “How can the development of the skills of education stakeholders be accelerated through the use of digital technology and in a digital environment? ». To answer this question, a critical review of the literature first clarified a few important concepts and identified a certain number of “good practices” in the use of digital technology to develop innovation. Next, schools from four different countries (Bulgaria, Finland, Belgium, France) tell us how, in their particular context, they have tried to answer the question posed and with what effects.
