The headline dollar
Current operating spending per student, shown three ways. The first is what each district reports. The second and third are the honest ones for comparison.
| Centralia SD 135 | Oak Valley Union Elementary | |
|---|---|---|
| Per student, as reported | $19,393 | $19,181 |
| Per student, price-adjusted Divided by the local price level, so both figures are in the same money. | $19,402 | $19,215 |
| Per student, price-adjusted, excluding transport Transportation provision varies enormously between districts and states. Removing it compares the parts both districts actually do. | $18,629 | $18,988 |
| Capital spending per student Buildings and land, reported separately and never folded into the operating figures above. It is lumpy: a district mid-build looks expensive for two years. | Locked | Locked |

How CA funds its districts
LCFF — Local Control Funding Formula: a base grant per pupil plus supplemental and concentration grants driven by low-income, English-learner and foster-youth counts.

What is actually different
Share of each district's operating dollar, Centralia SD 135 minus Oak Valley Union Elementary. Two pie charts side by side are almost impossible to read against each other; this is the same data as one chart.

What the money buys
Staffing levels are the most direct thing a budget converts into.
| Centralia SD 135 | Oak Valley Union Elementary | |
|---|---|---|

| Students per counsellor | Locked | Locked |
| Students per administrator | Locked | Locked |
| Total salaries All staff, not teachers alone. The federal survey does not separate teacher pay. | Locked | Locked |
Who they serve
The answer to "but they serve different kids" — which is usually a fair objection.

Results, and results for the money
Stability and risk
The homebuyer’s real question: what is likely to change after I move in?
Centralia SD 135
- Declining enrollment Enrolment fell more than 5% over five years. Enrolment decline is the single best predictor of school closures and programme cuts.
- Federal cliff exposure More than 20% of revenue is federal, a share that is unusually exposed when temporary federal programmes end.
Oak Valley Union Elementary
No stability flags raised.

Enrolling a child
Is a seat at your zoned school guaranteed?
Centralia SD 135
We have no such statement from this district — which is not the same as a promise that your zoned school has room. Most districts never publish the policy in either direction, and we have read only a fraction of the ones that do. Ask the school office directly whether your address’s school is enrolling at your child’s grade level before you sign anything.

Ask the school office directly whether your address’s school is enrolling at your child’s grade level before you sign anything.
- This is the district’s own published wording, not our summary of it. Policies are rewritten between enrolment seasons and a page can be out of date the day after we read it — the school office is the only authority on whether a particular grade at a particular school is full right now.
- A warning here is about capacity, not about your address. It does not mean your child will be moved; it means the district has told you in writing that it may move them.
Comparability notes
- Cross-state comparison. Dollars below are shown both as reported and adjusted to a common price level, because a dollar buys different amounts of teacher in IL and CA.
- At least one district sits outside a metro area with its own published price index, so its cost adjustment uses the statewide index. That is a coarser adjustment.
What these numbers are, exactly
- Finance: US Census Bureau Annual Survey of School System Finances (F-33), fiscal year 2024.
- Enrolment, staffing and directory: NCES Common Core of Data via the Urban Institute Education Data Portal, 2024.
- Child poverty: Census SAIPE school-district estimates, 2024.
- Price levels: BEA Regional Price Parities, 2024.
- Districts self-report to the F-33 survey. States differ in what they count as an operating expense, and several pay teacher pensions centrally so that cost never appears in a district’s books. No arithmetic fixes that; we name it instead.
- Property tax basis and borrowing: the same F-33 filing, revenue codes T06 and T02 and the long-term debt schedule (_19H, _21F, _31F, _41F).
Who decides, and what it costs you
Every band above this one asks what a district spends. This one asks who chose to.
Centralia SD 135
The district levies its own school tax
This district raises property tax in its own name. Who sets the rate varies by state — an elected board in some, a public vote in others — but the levy is the school system’s own, and it is the part of a tax bill that school politics moves most directly.

| School property tax levied, per student Only for districts that levy in their own name. Blank where the county or town levies instead — see the cards above, and read the next row. | $3,496 | $700 |
| Appropriated by the county or town, per student What the parent government handed the schools, for dependent systems. This is a general appropriation, not solely property tax. | — | — |
| Property tax as a share of all revenue How much of the budget rides on local property values, and therefore on local votes. | 12.6% | 3.1% |
| Long-term debt already owed, per student The balance at the end of the year, for scale. Repaid over decades, so it is a commitment made by earlier boards rather than a bill arriving now. | Locked | Locked |
| Debt service as a share of spending Interest plus principal repaid this year, against total spending. This is the part of the debt that is being paid now, out of money that would otherwise reach a classroom. | Locked | Locked |
| New long-term debt issued, per student Money borrowed during fiscal year 2024, as reported to the federal survey. What this figure does and does not tell you is set out under the table. | $0 | $0 |
- Centralia SD 135: issued no new long-term debt in fiscal year 2024. That is a reported zero, not a gap in the data.
- Oak Valley Union Elementary: issued no new long-term debt in fiscal year 2024. That is a reported zero, not a gap in the data.
- A figure in the borrowing row is not a bond voters approved. The federal survey records debt issued, and that includes refinancing existing debt at a new rate — which changes nothing about what a district owes — as well as certificates of participation and lease-revenue debt, which in many states a board can issue with no referendum at all. To find out what was actually on a ballot, check the county election office.
- Debt is repaid over decades. A large balance per student is a commitment made by earlier boards and earlier voters, not a bill arriving this year. The debt service row above it is the part being paid now.
