The purpose of this qualitative case study was to ascertain the perceptions of a principal regarding leadership insights into the ability to lead effectively in urban and multicultural education settings. The researcher determined that the potential existed for this participant, who was actively working to address issues brought on by diversity, to serve as a role model for culturally-responsive teaching through a case study. The increasing diversity among prekindergarten to Grade 12 students requires a more adequately trained, culturally aware faculty and staff. This case study used the theoretical lenses of the critical race theory, the model of Black identity development, and White identity development to examine the experiences of diverse cultures upon academic social structures. Four main research questions guided this study to determine the principal's ability to lead in a multicultural urban setting effectively: (a) what are the principal's perceptions about cultural awareness and his/her responsibility for serving increasingly diverse students, staff, and communities; (b) in what ways does a principal's perceptions of his/her capacity to lead effectively and demonstrate cultural awareness in an urban school with increasingly diverse students, staff, and communities evolve in practice over time; (c) what are the principal's perceptions of their past effectiveness to lead in a culturally responsive manner while serving increasingly diverse students, staff, and communities; and (d) what are the principal's perceptions of their preparedness to lead in a culturally responsive and culturally competent manner while serving increasingly diverse students, staff, and communities. School principals play a critical role in improving schools. This in-depth study interviewed a principal that had demonstrated 3 years of effective multicultural leadership experience over a diverse ethnic and gender population of students within the public urban school system.
