Student transportation funding

Getting students to school is funded by its own formula under RCW 28A.160.192, separate from basic education. It is based on the students a district actually carries and how far they travel - so rural districts with long routes, and districts running required special education routes, feel changes here most.

How transportation is funded

Transportation has its own allocation rather than being folded into the per-student basic education amount. The state's formula responds to ridership and distance, which is why two districts with identical enrollment can receive very different amounts.

Two exclusions matter for reading any transportation figure. Bus purchases are not in the general fund at all - they run through the separate Transportation Vehicle Fund. And the per-student figures below are per enrolled student, not per bus rider: most students never board a bus, so the real cost of carrying one student is far higher than these averages suggest.

177 of 315 districts spent more than allocated

Statewide that is $774 of general-fund transportation spending per enrolled student in 2024-25, against $783.0M allocated.

Transportation is the least uniform of the three published gaps: 177 of 315 districts spent above their allocation, meaning a substantial minority spent less than the formula provided. Geography, not policy, explains most of that split.

Where the gap is largest

Ranked by per-student difference. Small rural districts dominate: long routes over sparse territory cost roughly the same to run whether twenty students or two hundred ride them.

How to read these numbers

The spending side is F-196 program 99, general fund only. Because bus purchases sit outside the general fund, this figure understates the full cost of running student transportation - it describes operations, not fleet replacement.

This site does not attempt to reproduce the state's STARS allocation model, which computes an expected cost from ridership and distance. The comparison here is between what a district received and what it spent, which is a narrower question than whether the formula is correctly calibrated.
