About this project

The Stanford Education Data Archive (SEDA) aims to harness data to improve educational opportunity.

Background

The Stanford Education Data Archive (SEDA) is an initiative aimed at harnessing data to help scholars, policymakers, educators, and parents learn how to improve educational opportunity for all children.

Racial, socioeconomic, and gender disparities in academic performance and educational attainment are stubborn features of the U.S. educational system.These disparities are neither inevitable nor immutable, however. They have been produced by—and so may also be reduced by—a welter of social and economic policies, social norms and patterns of interaction, and the organization of American schooling.



SEDA includes a range of detailed data on educational conditions, contexts, and outcomes in school districts and counties across the United States. It includes measures of academic achievement and achievement gaps for school districts and counties, as well as district-level measures of racial and socioeconomic composition, racial and socioeconomic segregation patterns, and other features of the schooling system. The data are publicly available here, so that anyone can obtain detailed information about American schools, communities, and student success.

We hope that researchers will use the data to generate evidence about what policies and contexts are most effective at increasing educational opportunity, and that such evidence will inform educational policy and practices.

Who We Are

SEDA Development Team

Sean Reardon
Project Director & Professor of Poverty and Inequality in Education, Stanford University
Sean Reardon is the endowed Professor of Poverty and Inequality in Education and is Professor (by courtesy) of Sociology at Stanford University. His research focuses on the causes, patterns, trends, and consequences of social and educational inequality, the effects of educational policy on educational and social inequality, and in applied statistical methods for educational research. Reardon is the developer of the Stanford Education Data Archive (SEDA). Professor Reardon received his doctorate in education in 1997 from Harvard University. He is a member of the National Academy of Education and the American Academy of Arts and Sciences.

Andrew Ho
Professor of Education, Harvard University
Andrew Ho is the Charles William Eliot Professor of Education at the Harvard Graduate School of Education. He is a psychometrician whose research aims to improve the design, use, and interpretation of test scores in educational policy and practice. Ho is known for his research documenting the misuse of proficiency-based statistics in state and federal policy analysis. He has also clarified properties of student growth models for both technical and general audiences. His scholarship advocates for designing evaluative metrics to achieve multiple criteria: metrics must be accurate, but also transparent to target audiences and resistant to inflation under perverse incentives. Ho is a member of the National Assessment Governing Board that sets policy for the National Assessment of Educational Progress. He holds his Ph.D. in Educational Psychology and his M.S. in Statistics from Stanford University. Before graduate school, he taught middle school creative writing in his hometown of Honolulu, Hawaii, and high school physics and AP physics in Ojai, California.

Erin M. Fahle
Assistant Professor, St. John’s University School of Education
Erin Fahle is an Assistant Professor of Administrative and Instructional Leadership at the St. John’s University School of Education. In her work, she develops and applies complex statistical methods to study the variation in students’ educational experiences across the U.S., with a focus on understanding the mechanisms that reproduce educational inequalities. Erin is particularly interested in how gender limits children's educational opportunities within their homes, schools, and neighborhoods. Her research on gender inequality has been published in Educational Researcher and featured in the New York Times and the Atlantic. She holds a Ph.D. in Education Policy from Stanford University, as well as a B.S. in Mathematics (2008) and a M.S. in Applied Mathematics and Statistics (2009) from Georgetown University.

Benjamin R. Shear
Assistant Professor, University of Colorado Boulder
Benjamin Shear is an assistant professor in the Research and Evaluation Methodology program at the University of Colorado Boulder, College of Education. His primary research interests address topics in psychometrics and applied statistics, including validity theory, differential item functioning, and the application of diagnostic classification models. His work aims to inform our perspectives about test score meaning and use for research and accountability purposes, and to help answer questions such as, “what do test scores measure, and how do we know?” As a former high school mathematics teacher, his work often focuses on applications in mathematics education. His research in applied statistics seeks to improve the use of quantitative methods by education researchers measuring student learning, evaluating education policies, or studying inequality. This work is often carried out collaboratively with researchers working in other areas and through his teaching.

Kenneth Shores
Assistant Professor, Pennsylvania State University
I am an Assistant Professor at Pennsylvania State University studying education inequality and policy tools for its remediation. Relying on quantitative methodologies, this research includes both description and prevention/intervention. On the descriptive side, I am primarily interested in using large datasets to document racial/ethnic and socioeconomic disparities in student learning and educational policy (e.g., school disciplinary policy). I have additional work using conjoint survey designs to describe individual understanding of and preferences for social inequality. On the prevention/intervention side, I use quasi-experimental methods to identify the effects of environmental contexts on student outcomes as well as policies that are effective at remediating outcome inequality.

Ericka Weathers
Assistant Professor, Pennsylvania State University
Ericka S. Weathers is an Assistant Professor of Education at the Penn State College of Education. Dr. Weathers uses quasi-experimental methodologies to examine the impact of structural inequality on educational opportunities and outcomes in topic areas such as school finance, school discipline, academic achievement, and special education. Her current work explores school segregation as well as federal, state, and local education policies as possible determinants of racial disparities in school district revenue and expenditures.
