Reading the Conroe numbers
Two things distinguish Conroe ISD's 0.950%. First, it is nearly tied with Magnolia ISD — $26 a year separates them on a $300,000 home, small enough to be noise against a single reappraisal. Second, its 0.280% debt-service component is the second-smallest of the ten, which is why the total lands where it does despite a mid-pack operations rate. The comparison buyers around Conroe actually face is against Splendora ISD, since inventory with a Conroe mailing address can be zoned to either district: that choice is worth $915 a year at $300,000, every year the home is owned.
A $300,000 home zoned to Conroe ISD pays $444 more school tax each year than the same home in Richards ISD, the county's lowest-rate district, and $917 less than in New Caney ISD, its highest.

The City of Conroe levy on top
The 2025 city table lists City of Conroe at 0.427%. Inside the city limits — in the Montgomery County portion, for cities that cross county lines — a Conroe-zoned bill runs 1.907% of value — $5,721 at $300,000 — while the same home outside any city stays at 1.480%. City limits and district lines are independent boundaries; a parcel can be inside either, both, or neither.
22 special districts give Conroe as their city in the Comptroller's district database. A parcel inside one adds that district's own rate on top of all of the above — the district index carries each rate and each district's reported debt.
