The purpose of this paper is to answer the question how the concept of diversity can be understood in educational context. As it is argued, basing on the literature review, the diversity notion proves to be very contextual and impossible to close in the frames of only one definition. An educationally adequate understanding of diversity and its complexity by school leaders and all others involved in educational processes is a key element when we think of properly using the diversity potential in supporting developmental processes in schools. On one hand, it requires but, on the other hand, enables flexibility in the organization of those processes. This kind of flexibility and openness changes the educational perspective and highlights the new role of education, which is the promotion of the joy of learning and the connection of this process to the individual experiences of all. That is why understanding diversity seems to be one of the key elements important for educational leadership
