The main purpose of that paper is to consider how important for school leaders is competency of creating a vision and concept of the school together with all interested parties, and the competency of effective communication of a vision and concept of the school. The research was based on the mixed methodology including quantitative and qualitative research methods (in the first stage of research took part 2824 respondents, which is 11% of all school head teachers in Poland). The results set out that both discussed competencies are important for educational leadership (the dominant: "very important"). It is worth to stress that women more frequently than men consider the competency of creating a vision and concept of the school as important for an educational leader. The head teachers' declarations concerning their possession of these competencies show that the majority of them have some sort of problems with their practical application. According to Jan Łuczyński, the creation of a concept of the school is one of the most important tasks of head teachers, and therefore it may be alarming that 6% of the surveyed head teachers declared not having this competency.
