# Learning component by ID

`GET /learning-components/{identifier}`

Fetches a single LearningComponent by its unique identifier.

A LearningComponent represents a single, well-defined skill or concept that students are expected to learn. Learning components are granular units of learning that break down broad state standards into teachable and measurable parts at the level of a lesson, activity, or assessment question.

Use this endpoint when you need to:
- Display the full details of a specific learning component
- Retrieve the skill description and metadata for a known learning component
- Access attribution information for learning components used in your application

Learning components(LCs) are developed through expert-driven processes with input from experienced educators. Currently, LCs are available for mathematics standards across multiple states, with more subjects and states being added over time.
