The Educational Opportunity Project (EOP) at Stanford University will publish new research and data from the updated Stanford Education Data Archive (SEDA), a comprehensive online national database of academic performance measuring educational opportunity in school communities.

SEDA 4.0 includes:

• 430 million Math and Reading and Language Arts test scores from 3-8th grade students.
• 2 new years of EDFacts data: 2016-2017 and 2017-2018 school years.
• Updated data for all 50 states and Washington D.C.
• New research about trends in academic achievement and educational opportunity. 
• An enhanced Opportunity Explorer interface for users to engage with new data and generate high quality data visualizations.   

The data are free to access through the website, which houses the Opportunity Explorer, an interactive tool that enables users to generate detailed charts and maps of achievement data derived from US schools, districts, counties, and states. The newly enhanced Explorer interface allows users to select specific locations to compare estimates available online and in exportable reports. Users can filter data by race/ethnicity, gender, socioeconomic status, region (rural, town, suburban, and urban), school-type (charter and magnet), and age-group (middle, elementary, and combined). 

New research and discoveries: Professor sean reardon and his team will also post a new paper, Uneven Progress: Recent Trends in Academic Performance Among U.S. School Districts. Drawing on 10 years of test score data from every public school district in the US, the paper finds that trends in academic achievement and achievement gaps over the last decade vary considerably among school districts. Average test scores are increasing in some districts and declining in others. The same is true of achievement gaps. The wide variation in trends in these gaps can be partly explained by increasing segregation and inequality: Achievement gaps have been widening fastest in districts with high and growing levels of racial and economic inequality and segregation. Two new data discoveries based on these findings will be available on the EOP website. 

Coming soon in SEDA 4.1: in the Spring of 2021, the EOP will release 2018-2019 EDFacts data, as well as estimates for Puerto Rico, Native American students, and Bureau of Indian Education (BIE) schools.
