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.

Gavin SD 37Komarek SD 94
Per student, as reported $16,959$16,806
Per student, price-adjusted Divided by the local price level, so both figures are in the same money. $16,371$16,223
Per student, price-adjusted, excluding transport Transportation provision varies enormously between districts and states. Removing it compares the parts both districts actually do. $15,593$15,413
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. LockedLocked

Results, and results for the money

Deliberately not shown.Not shown yet. We will only publish an outcome comparison built on a source we can legally redistribute and that is genuinely comparable between districts. State proficiency rates are scored against cut scores each state sets for itself, and the one research dataset that fixes this forbids commercial use. We would rather show nothing here than show a number we cannot stand behind.

Stability and risk

No stability flags raised.

Registration Information

Registration runs through Skyward. Read August 23, 2026.

Komarek SD 94

We have not been able to find an enrolment page for this district, so every row in its column below says so rather than guessing at it. Ask the district's registration office directly.

Is a seat at your zoned school guaranteed?

Not known

Gavin SD 37

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.

Who decides, and what it costs you

Every band above this one asks what a district spends. This one asks who chose to.

Gavin SD 37

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.

Gavin SD 37Komarek SD 94
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. $9,080$20,799
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. 43.8%71.7%
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. LockedLocked
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. LockedLocked
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. $1,695$0

What this band does not answer yet

Who sits on the boardNot shown yet. Board members are real named people, and we publish a name only with the district’s own sentence and the URL it was read from — which means crawling every district’s board page, not inferring a roster. That crawl is under way state by state; this district’s board page is not read yet, so this section says nothing rather than something unsourced.
Funding measures on the ballotNot shown yet. School bond and levy results are published by each state and county election office, and only a handful publish them in a form a machine can read — the rest are PDFs, or nothing. We are adding them one state at a time and this state is still in the queue. Nobody has looked here, so this section is empty for want of a source rather than for want of an election, and the county election office holds the answer today.
