These are the next logical learning steps or more advanced concepts that students can progress to after working with the given academic standard (the given standard `buildsTowards` each of them). Proficiency in the given academic standard supports the likelihood of success in these standards. Use this endpoint when you need to: - Identify next steps in a learning progression after students master an academic standard - Design curriculum sequences that build on foundational skills - Map forward through learning pathways to understand where academic standards lead - Plan long-term instructional trajectories for students **Note:** Learning progression data is currently based on Student Achievement Partners' Coherence Map for Common Core State Standards (CCSS) 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 buildsTowards relationship](/knowledge-graph/graph-reference/learning-progressions#buildstowards) ## OpenAPI ````yaml /api-reference/knowledge-graph-api/openapi.yaml get /academic-standards/{caseIdentifierUUID}/builds-towards 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 - **Learning Components**: Granular, teachable skills that break down broad standards into actionable instructional units - **Standards Crosswalks**: Connections between standards and frameworks - **Curriculum**: Structured course content including courses, lesson groupings (units, sections, modules), lessons, activities, and assessments **Learn more:** - [Knowledge Graph Overview](/knowledge-graph/understanding-knowledge-graph/introduction) - [Academic Standards](/knowledge-graph/graph-reference/academic-standards) - [Learning Components](/knowledge-graph/graph-reference/learning-components) - [Standards Crosswalks](/knowledge-graph/graph-reference/standards-crosswalks) - [Curriculum](/knowledge-graph/graph-reference/curriculum) - [Quickstart](/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 operations - name: Hierarchy description: Hierarchical navigation operations - name: Learning Components description: Learning components operations - name: Learning Progressions description: Learning progressions operations - name: Search description: Search and discovery operations - name: Standards Crosswalks description: Standards crosswalks operations paths: /academic-standards/{caseIdentifierUUID}/builds-towards: get: tags: - Academic Standards - Learning Progressions summary: Standards a standard builds towards description: > Fetches the StandardsFrameworkItems that the specified academic standard builds **towards** via the "buildsTowards" relationship - the standards it is a prerequisite of.
