Returns every item in the framework's hierarchy, from top-level skills through to the most granular progression levels. Use `normalizedStatementType` to retrieve only skill statements and exclude the organizational groupings that structure them. Use this endpoint when you need to: - Retrieve the full contents of a durable skills framework - Export a framework's skills for mapping to your own content - Browse a framework's structure before navigating it with /durable-skills/{identifier}/children **Related topics:** - [XQ Competencies](/knowledge-graph/datasets/xq-competencies) - [Carnegie Skills Progressions](/knowledge-graph/datasets/carnegie-skills-progressions) ## OpenAPI ````yaml /api-reference/knowledge-graph-api/openapi.yaml get /durable-skills 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 US 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) - [Standards](/knowledge-graph/schema-reference/standards) - [Learning Components](/knowledge-graph/schema-reference/learning-components) - [Standards crosswalks](/knowledge-graph/schema-reference/standards) - [Curriculum](/knowledge-graph/schema-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: Durable Skills description: Durable skills frameworks and skills 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: /durable-skills: get: tags: - Durable Skills summary: Durable skills in a framework description: > Fetches a list of DurableSkill objects within a specific durable skills framework.

Durable skills frameworks organize their content hierarchically, and each framework uses its own vocabulary for the levels (for example "Competency" and "Component Skill" in XQ Competencies, or "Subskill" and "Indicator" in Carnegie Skills Progressions). Use `normalizedStatementType` for a classification that is consistent across frameworks, and `statementType` to see the framework's own label. These items are published outside the CASE Network, so they carry no CASE identifiers and are addressed by their Knowledge Graph `identifier`. required: - identifier - author - provider - license - attributionStatement - hasChildren properties: identifier: type: string description: >- The unique identifier for this item in the Knowledge Graph system.
