Curriculum

Schema last updated September 23, 2025.

Overview

Curriculum entities and relationships are referenced in the IM® v.360 Math Curriculum dataset.

Curriculum datasets align to Learning Commons’ K-12 curriculum ontology. Content metadata represents a publisher’s lessons and assessments, with the goal of being aligned to standards in Knowledge Graph. Instructional content preserves each curriculum’s hierarchy and sequencing. Metadata inferred from the content makes instructional dependencies explicit so you can analyze how concepts build over time.
