School leaders have the pedagogical, as well as the financial, responsibility at the school. It is the school leader's task to manage the competence development of the pedagogical use of ICT at school. Digital tools are being more used in teaching activities in those days, and the teachers have to develop their competence in order to guide the students in their learning. This paper is based on a case study conducted within the GNU project (Cross Border Nordic Education). The GNU project is an ongoing Nordic educational project between classes in grades 5-9 in Denmark, Norway and Sweden. The project is based on virtual communication between teachers and students, conducted with support of digital technology. The aim of the paper is to analyze the four dimensions of school leadership; 1) building vision and setting direction, 2) understanding and developing people, 3) redesigning the organization, and 4) managing the teaching and learning programme. The result shows that all of the school leadership dimensions work properly in one out of four different municipalities in order to support the teachers with the integration of digital tools in their teaching practices.
