The rapid growth of diversity within U.S. schooling and the heightened attention to the lack of equity in student achievement, school completion, and postsecondary attendance has made equity and diversity two of the principle issues in education, educational leadership, and educational leadership research. The Handbook of Research on Educational Leadership for Equity and Diversity is the first research-based handbook that comprehensively addresses the broad diversity in U.S. schools by race, ethnicity, culture, language, gender, disability, sexual identity, and class.The Handbook both highly values the critically important strengths and assets that diversity brings to the United States and its schools, yet at the same time candidly critiques the destructive deficit thinking, biases, and prejudices that undermine school success for many groups of students. Well-known chapter authors explore diversity and related inequities in schools and the achievement problems these issues present to school leaders. Each chapter reviews theoretical and empirical evidence of these inequities and provides research-based recommendations for practice and for future research. Celebrating the broad diversity in U.S. schools, the Handbook of Research on Educational Leadership for Equity and Diversity critiques the inequities connected to that diversity, and provides evidence-based practices to promote student success for all children.
