The instrument · No account, no form
PILLAR holds what United States school districts disclosed paying, what their states allocated them, and what those districts bought. Ask it something. You will get an answer with its source attached, or a straight admission that the record does not cover it.
An answer is only worth as much as the record behind it. Three things worth knowing before you rely on one.
The cut zone instrument publishes what 275 districts in four states paid named education vendors in FY2023 against FY2025, with the source and method printed on every page. No question required.
