- 4How it was checkedChecked: passed
- ✓ passedEvery grade × year weighted rate and school count recomputed independently in Python from the district CSV and matched (full QA §D). Student counts per grade are not separately compared.
The QA report behind this status · the report also lists what it does not check.
Each input metric’s own checks are on its metric tree (links above). Only the district-wide all-students series is covered by the packet’s 15 source-vs-database checks; that coverage is not claimed for any other block.
- 5Assumptions & caveatsAssumptions and caveats
- Grade '00' is kindergarten; the file has no pre-K.
