A total of 366 teachers working in high schools in the Şişli district of Istanbul participated in this study. The data were gathered through the “Organizational Culture Scale” and the “Teacher Leadership Scale.” The results of the study showed that the teachers' perceptions of school culture were focused on task-oriented culture, while their perceptions of teacher leadership were concentrated on organizational development. Positive and significant relationships were revealed between all subdimensions of school culture and those of teacher leadership. Support-oriented culture and task-oriented culture were found to be positive and significant predictors of the teacher leadership dimension of "organizational development." In addition, success-oriented culture and bureaucratic culture were positive and significant predictors of the teacher leadership dimension of "professional development." Furthermore, another teacher leadership dimension, "collaboration with colleagues," was positively and significantly predicted by support-oriented culture, task-oriented culture, and success-oriented culture.eninfo:eu-repo/semantics/openAccessSchool CultureTeacher LeadershipSchool DevelopmentSchool ImprovementArticle92310322
