In this article the author describes a collaborative project undertaken by two provincial education organizations to foster the leadership formation of school leaders. Leadership development through case inquiry was the focus of this innovative partnership between the Ontario College of Teachers and the Catholic Principals' Council of Ontario. The lived experiences of principals and vice-principals were used as pedagogy to explore the multiple and complex issues that emerge within educational leadership practice. Reflection, dialogue, and narrative writing extended the professional and ethical knowledge of these educators. The experiences of these educators resulted in the development of a leadership text that is now being used as a pedagogical and curriculum resource in educational leadership programs.
