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.
limits inference. The denominator is OSPI financial-summary enrollment, which mixes full-time-equivalent K-12 enrollment with birth-to-five special-education headcounts and various institutional programs, so it is not a count of individual K-12 students.
limits inference. CPI-U measures general consumer prices, not the prices schools themselves pay for staff, materials or services, and no school input-cost index is used here.
limits scope. Each comparison uses only its two endpoint school years; the years between them, including 2020-21, are not examined, even though the workbook holds other years.
limits inference. Nothing here establishes the causes of these changes, or speaks to adequacy, efficiency, educational quality or district reserve levels.
Washington General Fund expenditures per enrollment unit rose from $17,213.81 in 2021-22 to $19,371.31 in 2024-25, a nominal increase of 12.5%. Statewide General Fund expenditures were $18,468,601,374.12 in 2021-22 and $21,081,063,857.94 in 2024-25. This figure is not adjusted for inflation.
Adjusted for U.S. consumer prices, the increase in spending per enrollment unit is 0.8%. Adjusted for Seattle-Tacoma-Bellevue area consumer prices, it is a 1.5% decrease. Both use the mean of each school year's monthly CPI-U readings.
Selected federal relief programs spent $1,015,767,886.56 in 2021-22 and $3,491,983.06 in 2024-25. Excluding this spending, the nominal change is 19.1%, 6.6% after U.S. inflation and 4.2% after Seattle-area inflation. No relief-excluded measure exists for the 2018-19 or 2019-20 windows.
Starting from 2018-19, the nominal change to 2024-25 is 36.0%, 8.3% after U.S. inflation and 4.5% after Seattle-area inflation. Starting from 2019-20, it is 32.1%, 6.7% and 3.3%. Starting from 2021-22, it is 12.5%, 0.8% and -1.5%. None of these three starting years is privileged over the others.
The denominator is OSPI's financial-summary enrollment, which mixes full-time-equivalent enrollment for regular K-12 and other programs with birth-to-five special-education headcounts. It also includes skill-center summer programs, detention centers and other state institutions. It is not a count of individual K-12 students.
The largest per-unit increases came from Basic Education (+$977.79), Special Ed state funding (+$809.37) and districtwide support (+$397.47). The largest per-unit decreases came from ESSER III (-$314.27), ESSER II (-$251.63) and SLFRF enrollment stabilization (-$188.36).
The nominal change and the change after each of the two consumer price indexes, measured from 2018-19, from 2019-20 and from 2021-22, every window ending 2024-25.
The nominal change, the change excluding the selected relief programs, each of those after each of the two consumer price indexes.

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.
Capital projects, debt service and other funds outside the General Fund.
Other school years in the workbook, before this edition's period: 2014-15 through 2017-18.
School years inside the period that this edition does not read: 2020-21, 2022-23 and 2023-24.
The school years inside each comparison, which is measured between its two endpoints only.

Open questions
How much does the change in spending per enrollment unit vary between individual school districts? The statewide figures combine 318 to 326 reporting entities and could mask large differences between districts.
What would a school-specific input-cost index show over this same period, instead of a general consumer price index? CPI-U tracks what consumers pay, not what schools pay for staff, materials and services.
What happened in the school years between the compared endpoints, including 2020-21? Every comparison here uses only two endpoint years, so the path between them, including any single-year spikes or drops, is not described.
