Response

Successfully retrieved the learning component

Represents a single, well-defined skill or concept that students are expected to learn.

Learning Components are granular, precise representations of individual skills or concepts that break down broad educational standards into teachable and measurable parts. While state standards often define learning goals at a high level (sometimes encompassing multiple ideas across weeks of instruction), LCs operate at the level where instruction happens: during a lesson, an activity, or a single question.

Each LC is:

  • Instructionally actionable: Designed to guide daily teaching decisions and interventions
  • Aligned to academic standards: Connected to CASE-aligned standards through semantic relationships
  • Interoperable: Usable across diverse curricula, assessments, and platforms
  • Machine-readable and human-interpretable: Tagged with unique identifiers to support AI-driven content recommendations with transparent intent

LCs are developed through collaborative, expert-driven processes with input from experienced educators, primarily from Achievement Network (ANet).
