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.
| Robertson County | Granbury ISD | |
|---|---|---|
| Per student, as reported | $12,007 | $12,227 |
| Per student, price-adjusted Divided by the local price level, so both figures are in the same money. | $12,463 | $12,598 |
| Per student, price-adjusted, excluding transport Transportation provision varies enormously between districts and states. Removing it compares the parts both districts actually do. | $11,820 | $12,147 |
| 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 |

What is actually different
Share of each district's operating dollar, Robertson County minus Granbury ISD. Two pie charts side by side are almost impossible to read against each other; this is the same data as one chart.
| Robertson County | Granbury ISD | |
|---|---|---|
| Cents of each operating dollar reaching classrooms Instruction plus instructional staff support, as a share of current spending. | 71.2% | 65.2% |
| Administration share District office plus school administration. | 8.4% | 6.6% |
| Transportation share | 5.2% | 3.6% |
What the money buys
Staffing levels are the most direct thing a budget converts into.
| Robertson County | Granbury ISD | |
|---|---|---|
| Students per teacher This is a staffing ratio: total enrolment divided by teaching staff. It is NOT average class size, which no national source collects. Actual classes are larger than this number in every district. | — | 15.1 |

| Students per administrator | Locked | Locked |
| Total salaries All staff, not teachers alone. The federal survey does not separate teacher pay. | Locked | Locked |

Is a seat at your zoned school guaranteed?
Robertson County
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.

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.
- 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.
- Required the page says so, and the sentence is quoted.
- Mentioned only it comes up, but not as a requirement — often a sentence saying the district cannot demand it.
- Not mentioned we read the page and it was not on it. That is not the same as "not required".
- Page not read we have no enrolment page for this district.

How enrolling works
Locked 11 steps of the enrolment process — deadlines, appointments, proof of residency — are not shown. What to bring is above, and stays free.
- A blank row means the requirement did not appear on the page we read. It does not mean the district will not ask for it — published lists are routinely incomplete, and the registrar has the final word.
- Requirements change every enrolment season. Check the district’s own page, linked above, before you gather anything.
- A district cannot condition enrolment on your child’s immigration status: under Plyler v. Doe (1982) every child resident in the district is entitled to a free public education. If a district asks for something that would reveal status, you are not obliged to provide it.
- If your family is in temporary or shared housing, the McKinney-Vento Act lets a child enrol immediately without the residency and records documents listed here. Ask for the district’s homeless liaison by name.
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 TN and TX.
- 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.
Robertson County
The county or town levies it, not the district
This school system reports no property tax of its own. It is a dependent system: the county or city levies the tax and appropriates money to the schools. You still pay school property tax — the school board simply is not the body that sets it, and the appropriation is argued out at the county or city council.
Granbury ISD
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.
| Robertson County | Granbury ISD | |
|---|---|---|
| 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. | — | $9,597 |
| 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. | $3,794 | — |
| Property tax as a share of all revenue How much of the budget rides on local property values, and therefore on local votes. | — | 66.2% |
| 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 |
- Robertson County: issued no new long-term debt in fiscal year 2024. That is a reported zero, not a gap in the data.
- Granbury ISD: 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.

Funding measures on the ballot
Robertson County
We have not read TN’s election results, so this column is empty because of us and not because of Robertson County. Whether it has asked its voters for money is a question its county election office can answer and we cannot, yet.
Granbury ISD
$236.7M approved by voters across 3 measures.
| Election | Measure | Amount | Yes | Outcome |
|---|---|---|---|---|
| 2024-05-04 | Bond · Prop. A School Building, Buses & Technology |
$161.5M | 47.7% | Failed |
Locked 6 earlier measures in this district’s history are not shown.
From the state’s own election results file. Latest election on record: 2026-05-02.
What this state publishes: Bond elections only. Texas districts also ask voters to raise the maintenance-and-operations tax rate, and the Bond Review Board does not record those.
- A vote share is not an outcome. What it takes to carry varies by state and by measure — in some states a bond needs a supermajority and a minimum turnout while a levy on the same ballot needs half, so a clear majority can still lose. Every outcome shown here is copied from the state’s own results file, and the rule that applied is stated with the coverage above. Where that file stated no outcome we show the vote share and no verdict, rather than working one out from the percentage.
- These are the measures a district put to its voters, not its whole tax bill. A property tax bill also carries county, city and state levies that have nothing to do with schools, and in most states a school board can issue some kinds of debt with no vote at all.
