# 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

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/datasets/learning-components) that various [Academic Standards](/knowledge-graph/datasets/academic-standards) have in common in order to calculate a similarity score.
