School spending ยท Edition 0002

Washington school spending rose 12.5 percent per enrollment unit, or 0.8 percent after U.S. consumer-price inflation

How much did Washington public-school spending per enrollment unit change between 2021-22 and 2024-25, and how much of that change is inflation?

Published answer

Washington school districts and tribal compact schools report General Fund spending to OSPI's F-196 financial summary. Between the 2021-22 and 2024-25 school years that spending rose 12.5% per enrollment unit, from $17,213.81 to $19,371.31, and the earlier year included $1,015,767,886.56 of selected federal COVID relief spending against $3,491,983.06 in the later year. After adjusting for U.S. consumer prices the increase was 0.8%; after Seattle-area consumer prices it was a 1.5% decrease. The denominator, OSPI's financial-summary enrollment, mixes full-time-equivalent K-12 enrollment with birth-to-five special-education headcounts and institutional programs, so it is not a simple student count. Of the 326 reporting entities the workbook lists, 318 report General Fund spending in 2021-22 and 319 in 2024-25, and 319 and 326 carry an enrollment value in those years.

Scope

The 326 reporting entities listed in OSPI's ten-year F-196 financial summary, covering Washington school districts and tribal compact schools. The number that reports a value differs by school year, so the roster is 326 and the reporting count is not: 313 entities report General Fund expenditures in 2018-19, 311 in 2019-20, 318 in 2021-22 and 319 in 2024-25, and 323, 319, 319 and 326 rows carry an enrollment value in those years. Each statewide total is the sum of the rows that carry a value in that year, which equals OSPI's own total row to the cent.

Four school years are read from the workbook: 2018-19, 2019-20, 2021-22 and 2024-25. Each carries its expenditures, its enrollment measure and the ratio of the two. Every comparison is between two of those years, so these are endpoint comparisons and not a continuous annual series. The workbook holds the other school years in this span, including 2020-21, and this edition does not read them. Each inflation window runs from September to August of the same school year.
