The proliferation of leadership policies in education, especially in secondary education, had a major role in transforming schools into complex organizations, with a major impact on the role of teachers and how they carry out their work. Thus, the concepts of educational management, training, leadership, have become very topical, imposing new coordinates such as excellence in education, the teaching act as an end and assuming responsibility for the needs, standards and expectations of the organization. Leadership is an art and a science. There are leaders in management positions who fail to have results due to the lack of expertise and proper management tools. On the other hand, a manager that has no leadership qualities will always have problems with building and motivating a team. Developing a school, seen both in terms of decentralization and about the needs and skills of modern society implies a direct and indirect development of the qualities and behavior of the manager, seen as a key element to the motivation and involvement of teachers. So, we talk about a successful leader. If a school is functioning, that does not mean that it is a successful one. It is important in this case the way it is run, the principles and values that are reflected in practice.
