This article introduces a quantitative research into how the leadership team members of 49 basic education schools in the city of Vantaa, Finland, experienced the realisation of strategic leadership in their leadership teams' work. The data were collected by a survey of 24 statements, rated on a five-point Likert scale, and analysed with the Statistical Package for the Social Sciences (SPSS). The only variant explaining the differences in experiencing the realisation of strategic leadership in the leadership teams' work statistically, almost significantly, was the leadership team membership.
