# Standards crosswalks

> Reference for standards crosswalk relationships in Knowledge Graph: map state mathematics standards to Common Core using Jaccard similarity and learning component overlap.

[Dataset last updated July 2, 2026.](#dataset-release-history)

## Overview

<Note>
  The Standards crosswalks dataset uses Standards
  [entities](/knowledge-graph/schema-reference/standards#entities) and
  [relationships](/knowledge-graph/schema-reference/standards#relationships).
</Note>

The Standards crosswalks dataset connects state standards to their closest matching Common Core State Standards (CCSSM).

It essentially measures how many [Learning components](/knowledge-graph/schema-reference/learning-components) that various [Standards](/knowledge-graph/schema-reference/standards) have in common in order to calculate a similarity score.
