This endpoint retrieves academic standards that share meaningful conceptual or skill-based links with the given academic standard, without implying a specific sequence or prerequisite order. These lateral connections highlight associations that can inform instructional design, identify reinforcing concepts, or reveal thematic links across academic standards. Use this endpoint when you need to: - Find academic standards with related content or skills for integrated instruction - Identify opportunities for reinforcing concepts across different academic standards - Design cross-curricular or thematic units that connect related academic standards - Discover alternative pathways or parallel concepts in curriculum planning **Note:** Learning progression data is currently based on Student Achievement Partners' Coherence Map for Common Core State Standards for Mathematics. Coverage for other subjects and frameworks may be limited. The endpoint returns paginated results. Use the `limit` and `cursor` parameters to control the number of results returned. **Related topics:** - [Understanding the relatesTo relationship](/knowledge-graph/entity-and-relationship-reference/learning-progressions#relatesto) ## OpenAPI ````yaml /api-reference/knowledge-graph-api/openapi.yaml get /academic-standards/{caseIdentifierUUID}/related-standards 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}/related-standards: get: tags: - Academic standards - Learning progressions summary: Related standards for a standard description: > Fetches StandardsFrameworkItems that are related to the specified academic standard through the "relatesTo" relationship.
