# Crosswalks for a standard

`GET /academic-standards/{caseIdentifierUUID}/crosswalks`

Fetches a list of standards that align to a specific standard through shared Learning Components.

This endpoint retrieves crosswalk relationships bidirectionally:
- **State standard → CCSS**: Pass in a state standard to get matching Common Core State Standards (CCSS)
- **CCSS → State standards**: Pass in a Common Core State Standards (CCSS) standard to get matching state standards across jurisdictions

Each crosswalk includes similarity metrics based on measurable overlap of Learning Components to help understand the strength and nature of the alignment.

Crosswalks provide a scalable way to extend mappings between CCSS and state-specific frameworks without independent matching logic. By leveraging the LC superset, crosswalks show where standards converge in content coverage.

Use this endpoint when you need to:
- Find Common Core State Standards (CCSS) standards that align to a state standard for content adaptation
- Find state standards that align to a Common Core State Standards (CCSS) standard across multiple jurisdictions
- Understand the similarity between standards
- Map content between Common Core and state frameworks
- Analyze the degree of overlap between standards

**Note:** Crosswalks are currently available only for Mathematics standards in states where LC alignment exists. Crosswalks are evidence-based (require at least one shared LC).

The endpoint returns paginated results. Use the `limit` and `cursor` parameters to control the number of results returned.
