Greater San Antonio is split among more than a dozen independent school districts (ISDs), and district lines do not follow city limits, ZIP codes or subdivision names. Two homes on the same road can be in different districts. If schools matter to your move, check the district and the zoned campus for each specific address before you make an offer.

How to check a district's current rating

The Texas Education Agency (TEA) grades every district and campus from A to F. TEA released its 2026 ratings on August 14, 2026. San Antonio Report and Texas Public Radio covered the local results; for example, Judson ISD improved from a D to a C and North East ISD rose a full letter grade (San Antonio Report, August 14, 2026). Look up any district or campus by name at TXschools.gov, TEA's official report-card site, which shows the overall grade plus student achievement, progress and college/career readiness scores.

I do not rank schools or tell buyers which schools to choose. My job is to make sure you have the district facts for every home you look at, so you can decide what matters to your family.

Four steps before you write an offer

Confirm the district for the exact address. The MLS listing shows the district, but listing data can be wrong; check the district's own attendance-zone or school-locator tool.
Confirm the zoned campuses. Elementary, middle and high school zones are drawn separately and can change. Call the district if a home sits near a boundary.
Look at the property tax rate. The school district tax is usually the largest line on a San Antonio-area tax bill, and rates differ by district. See San Antonio property taxes.
Ask about transfers and programs. Many districts offer magnet, choice or transfer programs with their own deadlines; ask the district directly.
