To meet the needs of an increasingly diverse student population, leadership preparation programs must tackle the mutually-reinforcing goals of increasing the development of leaders from under-represented populations and cultivating culturally responsive leadership. This paper adds to the discussion of how best to improve leadership preparation by drawing on the literature related to equity in the leadership pipeline, and social justice and culturally responsive leadership frameworks, to examine one university-based leadership preparation program, highlighting the program's recent external partnership focused on increasing Black and Latinx administrators across the state and improving school leaders' cultural responsiveness.
