If you are buying a home in McKinney — or already own one — the school campus your address feeds into may not be the one you assume. McKinney ISD adopted new attendance boundary maps in late 2025, and the new maps took effect with the 2026–27 school year. For families shopping in growth areas like Trinity Falls, the practical rule is simple: verify the zoning for the specific address before you rely on it.
What changed
On December 15, 2025, the McKinney ISD Board of Trustees adopted new attendance boundary maps, effective the 2026–27 school year. The redraw was a growth realignment — McKinney continues to add residents at one of the fastest rates in Texas — and it included the closure or repurposing of three southern elementary campuses: C.T. Eddins, McNeil, and Wolford.
Boundary redraws of this kind do not move every address. Many homes keep their previous campuses. But some addresses that fed one elementary, middle, or high school under the old maps feed a different one under the new maps, which is why the campus printed in an older listing or an outdated school guide is not reliable on its own.
What it means for Trinity Falls
Trinity Falls, the 2,000-acre master-planned community in northwest McKinney, is zoned to McKinney ISD. The campus assignment most often published for Trinity Falls is:
- Naomi Press Elementary — located inside the community
- Scott Morgan Johnson Middle School
- McKinney North High School
That remains the most commonly published assignment for the community. However, because the new boundary maps took effect for 2026–27, the only safe way to state a given home’s schools is to verify the zoning for that specific address with McKinney ISD. A community as large as Trinity Falls — planned for roughly 5,000 homes, with space in its master plan for up to four on-site elementary schools — can have assignments that differ by section as later phases and campuses come online.
The district context
McKinney ISD’s most recent state accountability results give useful background for families weighing the district:
- In the Texas Education Agency’s 2025 accountability ratings, McKinney ISD earned an overall B, with a score of 88 — up from 84 in 2024.
- The district reported that its three comprehensive high schools earned A ratings in the 2025 framework.
The growth driving the boundary changes is visible in the census numbers: McKinney’s population grew from 195,308 in the 2020 Census to an estimated 236,001 as of July 1, 2025 — an increase of 20.8% in five years. Attendance boundaries in a district growing that fast are a moving target, and this redraw is unlikely to be the last one the district ever makes.
How to verify an address
- Start with the specific street address, not the neighborhood name. Boundaries are drawn on maps, and map lines can run through a community.
- Confirm the zoning with McKinney ISD for that address, for each level — elementary, middle, and high school. Do not assume the three levels changed or stayed the same together.
- Check the school year. The adopted maps are effective 2026–27. If you are buying now for a child who starts school later, ask the district whether further changes are planned that could affect the address again.
- Do not rely on a listing’s school fields alone. Listing data can predate the December 2025 adoption. Treat it as a starting point and verify against the district.
