Fetches a list of standards that align to a specific standard through shared Learning Components.
This endpoint retrieves crosswalk relationships bidirectionally:
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:
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.
