About

Knowledge Graph represents learning progressions based on Student Achievement Partner’s ↗ Coherence Map for Common Core State Standards for Mathematics ↗. Using learning progressions, you can trace backward or forward from a standard and identify logical paths through which students can progress in their learning.

Data relationship diagram

Data model diagram: StandardsFrameworkItem nodes connected by buildsTowards and relatesTo (Coherence Map learning progressions)
The diagram shows Learning Progressions (Coherence Map) only. The entity StandardsFrameworkItem is defined in Academic Standards; this page documents only the progression relationships between items.Example (CCSSM): Every node is a standard (a StandardsFrameworkItem from Common Core Math). A buildsTowards edge means earlier proficiency supports later—e.g. 3.OA.A.1 (Interpret products) buildsTowards 4.NBT.B.5 (Multiply multi-digit numbers). A relatesTo edge links standards that are conceptually related without a fixed sequence—e.g. 3.NF.A.1 might relateTo 3.NF.A.2 (same domain, reinforcing ideas). The diagram does not show the full standards hierarchy (framework → domain → standard); only progression links between standards.Edge list (source → relationship → target):
  • StandardsFrameworkItem → buildsTowards → StandardsFrameworkItem (e.g. 3.OA.A.1 → 4.NBT.B.5)
  • StandardsFrameworkItem → relatesTo → StandardsFrameworkItem (e.g. 3.NF.A.1 ↔ 3.NF.A.2)
See Relationships for full edge definitions. The StandardsFrameworkItem entity is defined in Academic Standards.

Relationships

A Learning Progression represents a sequenced set of skills or concepts that describe how student understanding develops over time. It is an ordered pathway of learning used to articulate dependencies between Academic Standards, Learning Components, or other instructional targets. Learning Progressions are grounded in research or expert consensus, support interoperability across curricula, and provide a framework for organizing content, guiding instruction, and enabling coherent learning experiences.

​
buildTowards

A buildsTowards relationship indicates that proficiency in one StandardsFrameworkItem supports the likelihood of success in another StandardsFrameworkItem. While this relationship reflects a directional dependency, it does not require that the first StandardsFrameworkItem be fully mastered before engaging with the second, nor that it is the immediate next step. Instead, it captures a meaningful progression in which earlier learning contributes to later achievement. (:StandardsFrameworkItem)-[:buildsTowards]->(:StandardsFrameworkItem)

​
relatesTo

A relatesTo relationship connects two StandardsFrameworkItems that share a meaningful conceptual or skill-based link without implying a specific sequence or prerequisite order. This non-directed relationship highlights associations that can inform instructional design, curricular coherence, or identification of reinforcing concepts across standards.
