This qualitative study aims to explore the core leadership practices of school principals in the Kingdom of Saudi Arabia. Given the exploratory nature of this study, a qualitative research design methodology was employed through which an in-depth, multi-perspective study of the practices of four secondary school principals was carried out. Employing a semi-structured interview protocol developed specifically for this study, data was collected from the principals and four teachers and four parents from each of the participating schools. The findings of the data analysis revealed that the principals demonstrated a repertoire of five core practices, namely, setting achievement goals, developing teachers, building strong relationships with parents, focusing on academic excellence and developing school climate. The principals enacted these core practices in a variety of ways. These core practices are discussed in detail along with the important implications for further research and practice.
