# 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 are granular representations of individual skills or concepts that break down broad [Academic Standards](/knowledge-graph/graph-reference/academic-standards) into teachable and measurable parts.
## Entities
### `LearningComponent`
Represents a single, well-defined skill or concept that students are expected to learn
It is a granular unit of learning used to describe instructional intent at the level of a Lesson, Activity, or Assessment. Learning Components 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.
