Sean F. Reardon


My research investigates the causes, patterns, trends, and consequences of social and educational inequality. In particular, I study issues of residential and school segregation and of racial/ethnic and socioeconomic disparities in academic achievement and educational success. In addition, my work develops methods of measuring social and educational inequality (including the measurement of segregation and achievement gaps) and methods of causal inference in educational and social science research.
