About the Project
Tom Kane at the Center for Education Policy Research at Harvard and Sean Reardon at Stanford’s Educational Opportunity Project have collaborated to provide the first opportunity to compare learning loss and ensuing recovery at the district level across the country. Last year, we and others reported that by the time all states returned to regular testing in the Spring of 2022, the average student in grades 3 through 8 had lost the equivalent of half a grade level in math achievement and a third of a grade level in reading achievement. In this latest report, we describe the first full year of post-pandemic recovery, between the Spring of 2022 and the Spring of 2023. 2023 Report
Without this research, many parents and policymakers have no way to know how the national trends have touched their students. According to Learning Heroes, over 90% of parents still think their child is at or above grade level. Our hope is that these resources will prompt local communities to plan more ambitious catch-up efforts before the federal pandemic relief aid expires. The interactive maps and corresponding data you will find on this site also provide insight on time spent in remote instruction, federal ESSER allocations and instructional spending per student. When available, achievement data are disaggregated by race and poverty status to provide a complete picture of the disparities in learning loss across the country.
Methodology
In the latest report, the researchers used test score results from roughly 8,000 school districts in 30 states to measure the extent to which test scores changed from Spring 2019 to Spring 2022 and from Spring 2022 to Spring 2023. Then the researchers used the methods developed by Reardon and colleagues to put the test scores from each state’s tests onto a common scale and to convert proficiency rates to “grade levels” of achievement (Reardon, Kalogrides, & Ho, 2021; Reardon, Shear, Castellano, & Ho, 2017). This allows us to measure changes in test scores between 2019 and 2023 on a common, interpretable scale for all school districts in these 30 states, despite the fact that they use different tests and proficiency thresholds.
Using these detailed data, the researchers report 1) the extent of academic recovery for each of the 30 states; 2) the extent to which the 2019-2022 losses and 2022-2023 improvements varied across school districts; and 3) how these patterns varied by district poverty rates and by student racial and economic background.

Walter H. Gale Professor of Education and Economics
Thomas Kane is an economist and Walter H. Gale Professor of Education at the Harvard Graduate School of Education. He is faculty director of the Center for Education Policy Research, a university-wide research center that works with school districts and state agencies. Between 2009 and 2012, he directed the Measures of Effective Teaching project for the Bill & Melinda Gates Foundation. His work has spanned both K-12 and higher education, covering topics such as the design of school accountability systems, teacher recruitment and retention, financial aid for college, race-conscious college admissions and the earnings impacts of community colleges. From 1995 to 1996, Kane served as the senior economist for labor, education, and welfare policy issues within President Clinton’s Council of Economic Advisers. From 1991 through 2000, he was a faculty member at the Kennedy School of Government. Kane has also been a professor of public policy at UCLA and has held visiting fellowships at the Brookings Institution and the Hoover Institution at Stanford University.
Sean Reardon
Professor of Poverty and Inequality in Education
Seam Reardon is the endowed Professor of Poverty and Inequality in Education and 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. He particularly studies issues of residential and school segregation, and of racial/ethnic and socioeconomic disparities in academic achievement and educational success. His 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. Professor Reardon is the director of the Educational Opportunity Project (EOP) and the developer of the Stanford Education Data Archive (SEDA), a database of roughly 500 million 3-8th grade standardized test scores that provides measures of educational opportunity for nearly every public school, district, county, and state in the US. He received his doctorate in education in 1997 from Harvard University and is a member of the National Academy of Education and the American Academy of Arts and Sciences. He is also an Andrew Carnegie Fellow and the recipient of the William T. Grant Foundation Scholar Award and the National Academy of Education Postdoctoral Fellowship.

Erin Fahle
Research Scientist, NWEA; Co-Director, Educational Opportunity Project at Stanford University
Erin’s research explores how social and school context affects gender, racial/ethnic, and socioeconomic inequalities in student’s access to educational opportunities and subsequent achievement. Dr. Fahle’s goal is to help states, districts, and schools identify areas for policy and practice interventions that can improve the educational circumstances of children across the U.S. She believes deeply that this work must be done in partnership with school leaders and is committed to designing research that reflects their perspectives. Her work has been published in Educational Researcher and the American Educational Research Journal and featured in media outlets including the New York Times, the Wall Street Journal, and NPR. Dr. Fahle 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.
