2025 state assessment data released for 49 states + D.C. - all at the EDC
Hello everyone!
Our team at the Education Data Center is excited to announce the release of the newest version of the State Assessment Data Repository, Version 3.0. We’ve included some of the highlights below.
In the following weeks, we will share a few last state updates with 2025 assessment data, and a final overview looking at academic trends over the past several years.
Please help us spread the word - consider emailing this email to a friend, or subscribe for data updates! Your comments, questions or feedback are always welcome at info@eddatacenter.org. We hope to hear from you!
Version 3.0 Highlights
NEW to Version 3.0
2025 data for 49 states + D.C. The repository now includes 2025 assessment data for 49 states and the District of Columbia. Vermont and Puerto Rico have not yet published 2025 assessment results.
New student subgroup data. New subgroup data has been added across several states, including data by gifted and talented status, “high needs” status in MA and CT, SLIFE (students with limited or interrupted formal education) status in MN, and new EL subgroups.
Additional research data. You asked, we listened! Our data files already included average scale score information (as available from SEAs), but researchers asked if we could include standard deviations as well. We have added this to the database and are actively working on incorporating this variable for more states through additional data requests.
And many more updates! The repository includes many other exciting improvements. Please visit our website for state-specific updates, our full technical documentation, and data changelog.
Access Version 3.0
There are two primary ways to access the data files:
You may access the data files here: https://www.zelma.ai/data. This page also documents data availability by state, subject, and year (including what years are missing from state data); new V3.0 technical documentation; and the new V3.0 codebook. You may choose to download the full dataset, or select individual states and years.
NEW to Version 3.0: We found that large .csv files were being truncated for users, particularly for Texas data. Beginning with V3.0, some files for CA, NY, and TX will be available by data level from the website (e.g., state, district, or school), rather than a single downloadable file.
The following states do not currently have subgroup data included for 2025: Arkansas, Idaho, Georgia, Mississippi, Oklahoma
You may access the data via our API, using R, Stata, or Python. This allows you to easily load the full V3.0 dataset into your software program.
If you or your organization have found the EDC data files useful for your research or understanding of education trends, please let us know at info@eddatacenter.org. We appreciate hearing from you, and this helps support our ongoing funding to sustain this work.
Ask Our AI Assistant, Zelma!
Zelma is the EDC’s AI-powered research assistant that can help answer your assessment-related questions as part of the State Assessment Data Repository. Version 3.0 data files are now used for all Zelma queries. Try it out! If there are data you do not see, let us know at info@eddatacenter.org and we will do our best to explain why or try to include the data in future data releases.
About the Education Data Center
At the EDC, we are committed to improving timely education data access and transparency. In December 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.
