The purpose for this study was to use the "KSH analytic framework" as a tool to provide insight into the organizational change process that, when considered, might result in lasting and significant school change. In this qualitative multi-case study of two urban comprehensive high schools, the researcher not only described the initiation and implementation strategies of reform by an external agency, but also described the lasting effect of the reform five years after the large nonprofit agency left the schools. The major research questions addressed in this study were: to what extent does "each" of the following, leadership, vision, teamwork, and action implementation, influence the school reform process initiated by an external agency as experienced in two urban high schools?
