# Learning progressions

> Schemas for Learning progressions relationships in Knowledge Graph, covering buildsTowards and relatesTo properties between standards items.

[Schema last updated Sep 23, 2025.](#schema-release-history)

## Overview

> [!NOTE]
>
> Learning progressions [relationships](#relationships) are referenced in the
> [Math Coherence
> Map](https://docs.learningcommons.org/knowledge-graph/datasets/learning-progressions/math-coherence-map.md)
> dataset.

Learning progressions detail how [standards](https://docs.learningcommons.org/knowledge-graph/schemas/standards.md) build towards and relate to each other.

## Relationships

### `buildsTowards`

Indicates that proficiency in one [`StandardsFrameworkItem`](https://docs.learningcommons.org/knowledge-graph/schemas/standards#standardsframeworkitem) supports the likelihood of success in another [`StandardsFrameworkItem`](https://docs.learningcommons.org/knowledge-graph/schemas/standards#standardsframeworkitem), capturing a directional progression without requiring strict prerequisite order

| Source node | Target node |
| :- | :- |
| [`StandardsFrameworkItem`](https://docs.learningcommons.org/knowledge-graph/schemas/standards#standardsframeworkitem) | [`StandardsFrameworkItem`](https://docs.learningcommons.org/knowledge-graph/schemas/standards#standardsframeworkitem) |

| Property | Description |
| :- | :- |
| `attributionStatement` | Textual credit that acknowledges the source or creator of a work, included when required by the content's license (e.g., Creative Commons BY) |
| `author` | Author of this content |
| `description` | Description of the item |
| `identifier` | Identifier of the item, either as textual strings or as URL (URI) links |
| `license` | License that applies to this content, as a URL or a license name |
| `provider` | Service provider, service operator, or service performer |
| `relationshipType` | Normalized value that defines the semantic meaning of the connection between the source and target entities (`buildsTowards`) |
| `sourceEntity` | Entity type from which the relationship originates (starting node in the connection) |
| `sourceEntityKey` | Source entity's property that contains its unique identifier; used to locate and reference the entity in the dataset |
| `targetEntity` | Entity type to which the relationship points (ending node in the connection) |
| `targetEntityKey` | Target entity's property that contains its unique identifier; used to locate and reference the entity in the dataset |

### `relatesTo`

Connects 2 [`StandardsFrameworkItem`](https://docs.learningcommons.org/knowledge-graph/schemas/standards#standardsframeworkitem)s that share a meaningful conceptual or skill-based link without implying sequence or dependency
