July 01, 2026

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.

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
