U.S. academic standards

Dataset last updated September 22, 2026.

Overview

The U.S. academic standards dataset uses Standards entities and relationships.

The U.S. academic standards dataset represents the official expectations for student learning across academic subjects and jurisdictions.


Source	Common Good Learning Tools ↗‘s CASE data ↗ for all 50 U.S. states
Supported grades	K-12
Includes	Math standards standards Social Studies standards Science standards
Dataset dependencies	None
REST API endpoints	Academic standards

Standards in this dataset are refreshed monthly, based on updates to Common Good Learning Tools ↗ data.When a new version of a standards framework is added, you can still query the superseded version. Superseded frameworks stay in the graph to preserve relationships (e.g., U.S. academic standards crosswalks) and allow querying across versions. The superseded framework will keep its identifier, and the new framework will have its own unique identifier.Frameworks are only removed if they are also removed from the source. If a framework identifier is missing, you can assume that it has been removed upstream.

To query	Directions
Current frameworks	Query frameworks with `isCurrent=true`. Only one framework is marked `isCurrent=true` for a given jurisdiction and subject. Frameworks become `isCurrent=true` at their implementation date (not publish date). This ensures that a current frameworks query doesn’t return standards that schools are not yet teaching.
Standards for current frameworks	Find a current framework (using `isCurrent=true`), then query its related standards. Filtering standards on jurisdiction and academic subject alone is NOT sufficient to get the most current standards or to disambiguate between standards belonging to different frameworks. Standards content may change, even under a stable framework identifier. If you cache standard text, re-read it after a release - a stable identifier does not mean stable content.

Use cases

Use case	Examples
Compare standards across states	Populate a standards menu across all 50 states Compare how the same concept is framed or taught in different jurisdictions
Align instructional content to official learning goals	Use standards as context to create AI-generated lesson plans Integrate standards data with your CMS for easy content tagging
Power richer analytics	Aggregate performance or coverage data by standard across all the states you serve Reduce maintenance burden on internal standards infrastructure
Query standards without state-specific naming quirks	Query by jurisdiction, subject, and grade without learning each state’s domain or cluster labels Traverse standards frameworks → standards groups → individual academic standards with normalized structure

Schema

The data represents standards frameworks, standards groups, and individual standards as a tree with the following entities and relationships:

Data model diagram: StandardsFramework and StandardsFrameworkItem entities
linked by
hasChild


Entities	`StandardsFramework` Root node for a jurisdiction’s standards (e.g. New York State Mathematics Learning Standards) `StandardsFrameworkItem` (child node to `StandardsFramework`) Top-level grouping like a Domain or Cluster (e.g. Operations and Algebraic Thinking or Number & Operations—Fractions) Standard within a domain or cluster (e.g. 3.NF.A.1)
Relationships	`StandardsFramework` → `hasChild` → `StandardsFrameworkItem` (e.g. New York Math framework → its top-level domains) `StandardsFrameworkItem` → `hasChild` → `StandardsFrameworkItem` (e.g. domain → cluster, or cluster → standard)

Dataset release history

Date	Changed
September 22, 2026	Filled in missing `statementType` and `normalizedStatementType` fields, made some reclassifications (e.g. “Standard Grouping” → “Standard”), and fixed incorrect `gradeLevel` and `inLanguage` values
September 9, 2026	Restored the `jaccard` property on `hasStandardAlignment` relationships (unintentionally removed in v1.12.0)
August 27, 2026	Added new frameworks; updated superseded frameworks to `isCurrent=false`; made updates and fixes to other standards frameworks
August 12, 2026	Updated standards from Common Good Learning Tools’ Rosetta ↗ data — refreshed frameworks and added new frameworks with `isCurrent=true`
June 18, 2026	Standards fixes for Montana Social Studies, New York Math, and Indiana Science
October 30, 2025	Added Washington, D.C. academic standards
September 23, 2025	First release from CASE Network 2 ↗ for all 50 U.S. states
