This endpoint retrieves all learning components that are aligned to a given academic standard through the "supports" relationship. Learning components break down broad academic standards into granular, teachable skills, making them actionable for lesson planning and assessment design. Use this endpoint when you need to: - Find the specific skills that compose a given academic standard - Identify granular learning targets for instruction aligned to an academic standard - Map learning components to your curriculum or assessment items - Understand how a broad academic standard breaks down into teachable units **Note:** Learning component alignments are currently available primarily for Mathematics academic standards. Academic standards in other subjects or certain special categories (e.g., Standards for Mathematical Practice, Pre-K, advanced math) may not have LC alignments. The endpoint returns paginated results. Use the `limit` and `cursor` parameters to control the number of results returned. **Related topics:** - [Understanding the supports relationship](/knowledge-graph/entity-and-relationship-reference/learning-components#supports) - [LC alignment methodology](/knowledge-graph/entity-and-relationship-reference/learning-components#creation-of-lcs) - [Available LC coverage by state](/knowledge-graph/entity-and-relationship-reference/learning-components#current-lc-mappings) ## OpenAPI ````yaml /api-reference/knowledge-graph-api/openapi.yaml get /academic-standards/{caseIdentifierUUID}/learning-components openapi: 3.0.3 info: title: Learning Commons Knowledge Graph REST API description: > REST API for accessing education knowledge graph data including academic standards, learning components, and curriculum information. **Key datasets:** - **Academic standards**: Official state standards from all 50 U.S. states sourced from 1EdTech's CASE Network - **Curriculum**: Structured course content including courses, lesson groupings (units, sections, modules), lessons, activities, and assessments - **Learning components**: Granular, teachable skills that break down broad standards into actionable instructional units - **Relationships**: Hierarchical and semantic connections between standards, learning components, and frameworks **Learn more:** - [Knowledge Graph Overview](/knowledge-graph/understanding-knowledge-graph/about-knowledge-graph) - [Academic Standards Dataset](/knowledge-graph/entity-and-relationship-reference/academic-standards) - [Learning Components Dataset](/knowledge-graph/entity-and-relationship-reference/learning-components) - [Quick Start Guide](/knowledge-graph/getting-started/quickstart) version: '0' servers: - url: https://api.learningcommons.org/knowledge-graph/v0 description: Production server security: - ApiKeyAuth: [] tags: - name: Academic standards description: Academic standards operations - name: Curriculum description: Curriculum and course operations - name: Hierarchy description: Hierarchical navigation operations - name: Learning components description: Learning component operations - name: Learning progressions description: Learning progression and prerequisite relationships - name: Search description: Search and discovery operations - name: Standards crosswalks description: Standards crosswalk operations - name: Standards frameworks description: Standards frameworks operations paths: /academic-standards/{caseIdentifierUUID}/learning-components: get: tags: - Learning components - Academic standards summary: Learning components for a standard description: > Fetches a list of LearningComponents that support a specific StandardsFrameworkItem.
