Education Data Center

At the EDC, we are committed to improving timely education data access and transparency. In 2023, we launched the State Assessment Data Repository in an effort to make state assessment data more widely accessible and engaging for the general public. This project grew from the need across organizations, education leaders, policymakers, researchers, and parents to be able to more easily find and use annual state summative assessment data. This data repository has grown to be the most comprehensive database of state assessment data in the United States. We believe that timely data access and transparency are critical for stakeholders to be able to make evidence-based decisions on how to support our nation's students and address their academic needs.

What is the State Assessment Data Repository? The State Assessment Data Repository is a comprehensive U.S. state assessment database that includes publicly-available assessment data from all 50 states and D.C. for students in Grades 3-8. This database integrates data across state-, district-, and school- levels, disaggregated by subject, grade level and student subgroups. The SADR includes data received from State Education Agencies (SEAs) via public data request for components that states have not posted publicly, such as data disaggregated by grade or demographic characteristics. The data do not include any student-level results. We also integrate important school and district identifiers from the National Center for Education Statistics (NCES) to support researchers seeking to understand student outcome data across a range of external datasets.

Data can be explored in two ways. First, data can be easily downloaded for research purposes, organized by state and year. Second, users can ask Zelma, our AI assistant, questions about the data using natural language. EDC empowers users to interact with and learn from the vast amount of assessment data available for each state. We caution that the results are NOT comparable across states, as states administer distinct assessments. Rather, for each state, Zelma can provide insight into trends and outcomes across districts and schools.
