Per student, as reported $13,255$11,955
Per student, price-adjusted Divided by the local price level, so both figures are in the same money. $12,858$11,874

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, and cannot honestly be shown across state lines. TX and AZ set their own tests and their own passing marks, so "% proficient" in one is not the same measurement as "% proficient" in the other. Sites that compare them anyway are comparing two different rulers.

Stability and risk

Slidell ISD

  • High debt burden More than 10% of total spending goes to interest and debt retirement, money that cannot reach a classroom.

Duncan Unified District (4228)

  • Declining enrollment Enrolment fell more than 5% over five years. Enrolment decline is the single best predictor of school closures and programme cuts.

Is a seat at your zoned school guaranteed?

Not known

Slidell ISD

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.

Slidell 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.
