# Learning components
> Reference for Learning components in Knowledge Graph: granular skills and concepts aligned to standards, with support for progressions and content tagging.
[Schema last updated May 27, 2026.](#schema-release-history)
## Overview
Learning components [entities](#entities) and [relationships](#relationships)
are referenced in the [Math learning
components](/knowledge-graph/datasets/math-learning-components) and [ELA
learning components](/knowledge-graph/datasets/ela-learning-components)
datasets.
Learning components are granular representations of individual skills or concepts that break down broad [Standards](/knowledge-graph/schema-reference/standards) into teachable and measurable parts.
## Entities
### `LearningComponent`
Single, well-defined skill or concept that students are expected to learn
`LearningComponent`s are granular units of learning used to describe instructional intent at the level of a [`Lesson`](/knowledge-graph/schema-reference/curriculum#lesson), [`Activity`](/knowledge-graph/schema-reference/curriculum#activity), or [`Assessment`](/knowledge-graph/schema-reference/curriculum#assessment). They are aligned to academic standards, support interoperability across curricula, and serve as the foundational building blocks for organizing content, tracking progress, and enabling personalized instruction.
