Children of a standard

Fetches StandardsFrameworkItems that are direct children of the specified academic standard through the “hasChild” relationship.

This endpoint retrieves academic standards that are hierarchically organized under the given academic standard. This allows you to navigate down the standards framework hierarchy from domains to clusters to individual academic standards, or from any parent grouping to its children.

Use this endpoint when you need to:

Navigate down the standards framework hierarchy (e.g., from domain to academic standards)
Get all academic standards within a specific grouping or cluster
Build tree visualizations of standards framework structures
Explore the organizational structure of a standards document

Note: This returns direct children only, not all descendants. To get all descendants, you’ll need to traverse multiple levels.

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