Education Data Center

Education Data Center (EDC) is a US-focused hub for school test results designed for researchers, analysts, and education organizations.

Access large-scale education data

EDC provides the State Assessment Data Repository, a collection of state assessment test data. You can work with results across states, schools, and student groups to support reporting and research.

• Download prepared data files
• Filter indicators and compare results across locations
• Create charts to visualize trends and differences

Analyze with the Zelma AI tool

Zelma is built into the platform to help you explore the dataset in natural language. Instead of writing SQL or doing manual data prep, you can ask questions in plain English and receive:

• Data selections based on your query
• Visualizations generated from the results
• Insights to guide further analysis

Built for education stakeholders

EDC supports evidence-based decision-making, including evaluating program effectiveness, tracking performance over time, and identifying achievement gaps. The dataset is updated regularly to keep education statistics current and transparent.
