This paper focuses on one of the aspects most investigated and monitored in recent years by the Digital Economy and Society Index on the digitisation process in Europe--human capital, with an in-depth focus on primary school teachers. Human capital is one dimension underlying school digital capital, closely related to integrating digital into daily practices. Starting from this framework, the paper will present the results of a survey on the digital competencies of teachers from five European countries (Italy, Spain, Lithuania, Romania and Poland), carried out in the framework of the European project Erasmus+ CAVE (Communication and Visual Education in homeschooling). This survey is preparatory to a training intervention and didactic experimentation on digital education, foreseen in the project, and used as a theoretical framework of reference for the DigCompEdu survey, promoted by the European Commission. The teachers' profiles, as the output of the research, will be able to give stakeholders a picture of the investment of schools and teachers, in terms of the application of digital competencies on different educational processes: classroom teaching, assessment, professional training, preparation of teaching materials for the lesson and the implementation of competencies, including digital ones, of students.
