]Search academic standards
Searches for StandardsFrameworkItems using either semantic search or exact statement code match across all standards frameworks.
This endpoint supports two mutually exclusive search modes:
- Semantic search (
query): Full-text semantic search against the standard’s description. Results are ranked by relevance and include ascorereflecting vector similarity. - Code search (
statementCode): Exact statement code match (e.g., “3.NF.A.1”). Case-insensitive, no partial matching. All results carry ascoreof 1.0.
Exactly one of query or statementCode must be provided. Providing both or neither returns a 400 error.
Results can be narrowed further using the optional filters and support cursor-based pagination.
Use this endpoint when you need to:
- Find academic standards relevant to a concept or learning goal (semantic search)
- Look up an academic standard by its exact statement code
- Find all standards frameworks that include a specific statement code
- Filter search results by grade level, subject, or statement type
Note: Not all academic standards have statement codes - some organizational groupings may have null codes and won’t appear in code search results.

Query Parameters
Free-text query for semantic search against academic standard descriptions. Results are ranked by relevance score. Mutually exclusive with statementCode.
500The exact statement code to search for. Case-insensitive exact match only (e.g., "3.NF.A.1" matches "3.nf.a.1"). Mutually exclusive with query.
50Filter by grade level. Can be specified multiple times to include multiple grades.
Educational grade level
PK, K, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 Filter results by academic subject area. Academic subject area
English Language Arts, Mathematics, Science, Social Studies, Other Filter results by normalized statement type. Use this to retrieve only instructional standards (exclude organizational groupings) or to separate different types of framework elements. Normalized classification of a standards framework item

1 <= x <= 50Response
Successfully retrieved search results
A UUID referencing the item in the CASE Network published by 1EdTech. Use this identifier to retrieve the full standard details via GET /standards/{caseIdentifierUUID}.
The author or creator of this content, typically the organization that published the standards framework
The service provider or organization that makes this data available in the knowledge graph
A URL to the license document that applies to this content
A textual credit that acknowledges the source and creator of this work, as required by the CC BY 4.0 license. If you display or redistribute this standard, you must include this attribution statement to comply with the license terms.
Relevance score between 0 and 1. Higher values indicate stronger alignment with the search criteria. For semantic search, this reflects vector similarity. For exact code match, the score is always 1.0.
0 <= x <= 1A short, human-readable code that uniquely identifies this standard within its framework context (e.g., "3.NF.A.1", "5.NF.A.1"). May be null for organizational groupings.
