A StandardsFrameworkItem represents an individual statement or structural element within a standards framework. These items can be normative statements that specify what students should know or be able to do (e.g., "Describe the impact of a transformation matrix on a graphical object"), or organizational groupings that structure the framework (e.g., domains, strands, clusters). Use this endpoint when you need to: - Display the full details of a specific academic standard in your application - Retrieve the exact statement text, grade levels, and classification for a known academic standard - Trace an academic standard back to its source in the CASE Network via the CASE identifiers The response includes the statement text, grade level(s), subject area, jurisdiction, and all source attribution required by the CC BY 4.0 license. **Related topics:** - [Understanding StandardsFrameworkItem vs StandardsFramework](/knowledge-graph/entity-and-relationship-reference/academic-standards) - [Standard classification types](/knowledge-graph/entity-and-relationship-reference/value-and-format-standards#normalizedstatementtypeenum) ## OpenAPI ````yaml /api-reference/knowledge-graph-api/openapi.yaml get /academic-standards/{caseIdentifierUUID} 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}: get: tags: - Academic standards summary: Academic standard by ID description: > Fetches a single StandardsFrameworkItem by its CASE UUID identifier.

StandardsFrameworkItems are the building blocks of academic standards documents. They can be: - **Learning expectations**: Normative statements that define what students should know or be able to do (e.g., standards, competencies, performance indicators) - **Organizational elements**: Structural groupings that organize learning expectations into coherent units (e.g., domains, strands, clusters, conceptual categories) Each item preserves the original statement text and metadata from state frameworks while including normalized properties that enable cross-framework queries and comparisons. Items maintain full traceability to their source in the CASE Network through CASE identifiers. required: - identifier - caseIdentifierUUID - author - provider - license - attributionStatement properties: identifier: type: string description: >- The unique identifier for this item in the Knowledge Graph system. This is a system-generated UUID that remains stable across data updates and can be used to reference this item in queries and relationships. caseIdentifierURI: type: string format: uri description: >- A URI referencing the equivalent item in the CASE Network published by 1EdTech. This identifier can be used to trace the corresponding standard in the CASE dataset. caseIdentifierUUID: type: string format: uuid description: >- A UUID referencing the equivalent item in the CASE Network published by 1EdTech. Use this identifier to trace the standard back to its authoritative source, establish equivalence with other systems using CASE data, or cross-reference with official state documentation that includes CASE identifiers. statementCode: type: string nullable: true description: >- A short, human-readable code that uniquely identifies this standard within its standards framework context. Typically alphanumeric (e.g., "3.NF.A.1", "A.1B", "MP1") and reflects the standards framework's internal coding scheme. This is the code educators use to reference standards in curriculum materials, lesson plans, and assessment systems. May be null for organizational groupings that don't have assigned codes. description: type: string nullable: true description: >- The full text of the standard or organizational element, describing what students should know or be able to do statementType: type: string nullable: true description: >- The original classification label used by the source standards framework to categorize this item (e.g., "Domain", "Cluster", "Strand", "Benchmark", "Practice Standard"). Unlike normalizedStatementType which standardizes across standards frameworks, this field preserves the exact terminology used in the state's official standards document, which can be helpful for maintaining consistency with state-specific materials and educator expectations. normalizedStatementType: $ref: '#/components/schemas/NormalizedStatementTypeENUM' description: >- A normalized classification that describes the broad functional role of this item, standardized across all standards frameworks regardless of how individual states label their standards. This enables cross-state queries like "find all actual standards" vs "find all organizational groupings". Use this field when you need consistent categorization across multiple jurisdictions. nullable: true jurisdiction: $ref: '#/components/schemas/JurisdictionENUM' description: >- The state, territory, country, or governing education agency responsible for publishing and adopting this standard. For U.S. state standards, this is the state name (e.g., "Iowa", "California"). This field is essential for filtering standards by location and understanding which standards apply to specific student populations or geographic regions. academicSubject: $ref: '#/components/schemas/AcademicSubjectENUM' description: The academic subject area for this standard gradeLevel: type: array nullable: true description: >- The educational grade level(s) for which this standard is intended. Values are strings to accommodate grade bands and special designations (e.g., "K", "PK", "9-12"). A standard may specify multiple individual grades or grade ranges. Use this field to filter standards appropriate for specific student grade levels. items: $ref: '#/components/schemas/GradeLevelENUM' inLanguage: $ref: '#/components/schemas/LanguageENUM' description: The language of the content, in BCP 47 format dateModified: type: string format: date nullable: true description: >- The date on which this element was most recently modified in the source system (CASE Network).

May include information about prerequisite knowledge, connections to other standards, or implementation notes from the source framework. author: type: string description: >- The author or creator of this content, typically the organization that published the standards framework provider: type: string description: >- The service provider or organization that makes this data available in the knowledge graph license: type: string format: uri description: A URL to the license document that applies to this content attributionStatement: type: string description: >- A textual credit that acknowledges the source and creator of this work, as required by the CC BY 4.0 license.
