Adaptive Learning created these standards-alignment packs from Learning Commons Knowledge Graph v1.11.0 by retaining current K-12 state Standards Frameworks and Items, excluding preschool-only rows, mapping K to grade 0 while retaining PK provenance on mixed-grade rows, splitting multi-grade items into per-grade files, and optionally retaining only hasChild taxonomy relationships. Standard descriptions are unchanged. hasChild is structural taxonomy metadata and is never treated as a prerequisite.

Georgia is excluded from the Learning Commons import because its upstream records assert CC BY-NC-SA terms. Georgia continues to use the project-authored GENERIC_K14 teaching graph without official Georgia standards text.
