Southlake school ratings and districts

By Mariela Lovo Ol, REALTOR® · Updated

Southlake, TX school ratings and districts start with a surprise for many buyers: four public school districts serve parts of the city. This page lists them, their official state ratings and how to confirm the campus for any home.

Which school districts serve Southlake?

The city's school directory lists Carroll ISD, Grapevine-Colleyville ISD, Keller ISD and Northwest ISD. Carroll ISD serves the majority of the city and describes itself as Southlake's largest district, with 11 schools and more than 8,400 students. The other three serve smaller areas, mostly near the east and west edges.

What are the official district ratings?

The Texas Education Agency's TXschools.gov lists these overall district ratings for the 2025-26 school year:

Carroll ISD: A, 93 out of 100. Grapevine-Colleyville ISD: A, 91 out of 100. Keller ISD: B, 84 out of 100. Northwest ISD: B, 82 out of 100.

A district rating averages many campuses. Use TXschools.gov to review the specific campuses tied to an address.

How does enrollment work in Carroll ISD?

Carroll ISD enrolls new students online, and students may register only at their zoned campus. The enrollment page includes an attendance-zone search map. Requests to attend a different campus go through the district's transfer application and are decided under board policy.

What if the home is in GCISD, Keller or Northwest ISD?

Use that district's own boundary tools and enrollment steps. Each district sets its own transfer rules, specialized programs and deadlines, so ask the district directly. Charter and private schools in the area run their own admissions.

How do I verify the schools for a specific home?

Start with the address, not the neighborhood name. Look up the property on the Tarrant Appraisal District or Denton CAD site to see the school district on the account, then use the district's zone map. Verify school assignment for any address directly with the district, because boundaries can change.

Keep your closing papers or lease ready, since enrollment asks you to show where you live.

Then search Southlake homes for sale in the zone you want, and read the Southlake community guide for how districts line up by area.
