This study aimed to explore the cultural barriers to change in public primary and secondary schools in Türkiye. The study is based on a qualitative research approach. The participants consist of 42 school leaders working in various primary and secondary schools in Türkiye. Data originated from semi-structured interviews and observations, and content analysis was conducted during the data analysis. Regarding the characteristics of school cultures, the participants emphasised an organisational culture that is open to innovation and solidarity among individuals. Concerning the cultural barriers to change in schools, the resistance to innovation was highlighted as linked to individual behaviour. Finally, the way in which school members resist change is important. The results highlight a lack of cooperation as one of the main barriers to change. Resistance to collaboration and lack of development of professional learning networks currently inhibit school change in Türkiye. The results show that cultural factors affect the success of change initiatives in schools that are open systems, and understanding and overcoming obstacles. Starting the change process in this way can transform schools into learning and developing organisations.
