What this dataset measures

Assembled to test a widely shared October 2026 claim that Washington has the 17th-highest cost per pupil, for 31st-place results, after ranking 20th a decade ago. Each table matches one number in that claim, and the NAEP table adds the nationally comparable test the claim's ranking only partly reflects.

Geography: Washington, United States
Unit of observation: State-year (spending and NAEP); Data Book edition (Kids Count rank).
Update cadence: Ad hoc; Census publishes school finance data annually, Kids Count each June, NAEP every two years.

Scores carry sampling error; small gaps between Washington and the nation may not be statistically significant.
2005-2011 values and the 2013 national value are omitted because they were not printed in the reports retrieved.
National declines after 2019 reflect the pandemic, so the drop is not specific to Washington.

Limitations and reproducibility

Manually transcribed: Values were transcribed from published PDFs and articles listed in sources; no code transforms the numbers other than sorting and ranking the 50 state spending values. Census's state API now requires a key and its summary workbook could not be parsed in our environment, so the state-by-state pairing was taken from a published ranked list and every value was checked against the Census FY2024 per-pupil chart.

Per-pupil spending is Census 'current spending' (operations), excluding capital outlay and debt service, and is not adjusted for inflation or regional cost differences.
The Kids Count education rank series has gaps (2016-2023 Data Books were not verified) because the Kids Count Data Center could not be retrieved; values for 2024-2026 come from news summaries of the Data Book, not the Data Center itself.
Kids Count Data Book years are publication years; the underlying indicator data are one to two years older.
NAEP national values for 2013 were not printed in the snapshot reports we retrieved and are left missing rather than filled from memory.
NAEP average scores have sampling error; differences of a few points may not be statistically significant. NCES flags 2003 values as significantly different from 2024.
