Knowledge Graph v1.12.0 (2026-08-12)

Data v1.12.0

• Added Carnegie Skills Progressions dataset
  • Employer-recognized skills progressions for high school students
  • Sourced from the Carnegie Foundation for the Advancement of Teaching and ETS ↗'s Skills Progressions, Vol. 1
• Added XQ Competencies dataset
  • Competencies for high school students
  • Sourced from the XQ Institute ↗'s XQ Competencies
• Updated US academic standards from CGLT data
  • Refreshed existing standards frameworks' content
  • Added new standards frameworks with new UUIDs and isCurrent=true
    • New frameworks are not yet aligned with Learning components.
      Currently, all Learning components → Standards alignments still reference the old standards.
  • Deprecated old standards frameworks with isCurrent=false (preserved existing relationships)
  • Removed isCurrent from StandardsFrameworkItem (remains on StandardsFramework)
  • Updated adoptionStatus to reflect CGLT values
  • Updated gradeLevel values to match CGLT source values

Knowledge Graph v1.11.0 (2026-07-09)

Knowledge Graph v1.11.0 (2026-07-09)

Data v1.11.0

Added and updated Academic Standards fields

• StandardsFrameworkItem
  • Added optional alternateStatementCode field for statement codes that are not included in the CASE specification ↗ but are commonly used by publishers, teachers, and other edtech practitioners – Currently populated for Texas Essential Knowledge and Skills (TEKS) and various other states' standards
• StandardsFramework and StandardsFrameworkItem
  • Updated author and attributionStatement fields to include mention of the state
  • Added isCurrent field that indicates whether the record is the most up-to-date version for the state-subject pair

Knowledge Graph v1.10.1 (2026-07-01)

Knowledge Graph v1.10.1 (2026-07-01)

Data v1.10.1

Fixed missing math Crosswalks

Restored math Standards Crosswalks between Texas and CCSS that were incorrectly removed in v1.9.0. Both the JSONL downloads and REST API have been updated. No other data was affected.

If you downloaded the Knowledge Graph JSONL files or queried the standards crosswalks during v1.9.0 or v1.10.0, re-download or re-query to pick up the restored data.

Knowledge Graph v1.10.0 (2026-06-18)

Knowledge Graph v1.10.0 (2026-06-18)

Data v1.10.0

English Language Arts (ELA) Learning Components

License and attribution statement values have been updated for each individual row.

Illustrative Mathematics

Improved data quality:

• Trimmed whitespace from fields
• Fixed inLanguage and gradeLevel fields where they didn't match ENUM
• Removed duplicate hasChild and hasReference relationships
• Updated mutuallyExclusiveWith relationship to always be bi-directional
• Added missing Material entities

Standards fixes

• Montana Social Studies - Several standards had normalizedStatementType incorrectly set to null
• New York Math - One standard had statementType and normalizedStatementType incorrectly set to null and was missing some Learning Component aligments
• Indiana Science - Some standards had subject incorrectly set to "Other"
• Removed a few Learning Components that were duplicated and causing inaccurate Jaccard scores for state Standards Crosswalks
