}Crosswalks for a standard
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 → State standards: Pass in a 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 CCSS standards that align to a state standard for content adaptation
- Find state standards that align to a 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.

Only return standards with a Jaccard score greater than or equal to this value. Use this to focus on stronger alignments.
0 <= x <= 1Maximum number of results to return. Default is 100. Maximum allowed is 1000.
1 <= x <= 1000Cursor for pagination. Obtain this value from the 'nextCursor' field in the previous response. Omit for the first page.
Response
Successfully retrieved list of crosswalked standards. If a state standard is provided, returns matching CCSS standards. If a CCSS standard is provided, returns matching state standards (optionally filtered by jurisdiction).
