Best Houston School Districts 2026: TEA Ratings, SAT Scores, and Real Estate Premium

Which Houston Metro School District Actually Moves the Needle on Home Values?

School district ratings are not just a parenting concern. They are one of the most reliable predictors of long-term home appreciation in the Houston metro. Buyers who understand the difference between an A-rated and a B-rated district, what that gap costs at closing, and how attendance zone boundaries can shift property values by tens of thousands of dollars, make dramatically better purchase decisions.

TL;DR: Tomball ISD is the only Houston metro district to earn a TEA A-rating in 2025, while Friendswood ISD and Pearland ISD round out the top tier with scores of 92 and 91 respectively. Homes inside A-rated district boundaries typically carry a 10-20% premium over comparable properties just outside the zone. Buyers targeting a specific campus, such as Carnegie Vanguard or Bellaire High School inside HISD, must verify attendance zone addresses before making an offer, because district-level ratings can mask campus-level performance swings worth hundreds of thousands in resale value.

How the TEA A-F Accountability System Works

The Texas Education Agency released the 2025 A-F ratings on August 15, 2025, covering performance from the 2024-2025 school year. Ratings reflect three weighted domains: Student Achievement (performance on STAAR exams and graduation metrics), School Progress (academic growth over time and relative performance against economic peers), and Closing the Gaps (outcomes by subgroup). Each domain scores 0-100; the lowest domain score becomes the district's overall score, which then converts to a letter grade.

In 2025, statewide results showed 24% of districts and 31% of campuses improved their letter grade compared to 2024. Only 15% of campuses saw a decline. For buyers, the critical distinction is between district-level ratings and campus-level ratings. A district may earn a B while hosting individual A-rated campuses, and those specific attendance zones command a steeper premium.

2025 TEA Ratings Snapshot: Houston Metro ISDs at a Glance

Here is a side-by-side comparison of the 13 major Houston metro ISDs. Median home price data draws from HAR, Realtor.com, and public appraisal district records. Graduation rate figures reflect TEA accountability data and district reporting for 2024-2025. SAT averages come from TEA's class of 2024 SAT release, which reflects the most recent published statewide data.

Tomball ISD: The Only Houston Metro A-Rated District in 2025

Tomball ISD is the sole Houston-area district to earn an A in the 2025 TEA accountability cycle, building on a track record that has made it a destination for buyers from northwest Harris County and Montgomery County. The district serves approximately 23,300 students across 22 campuses for the 2024-2025 school year, with enrollment growing steadily each year. The class of 2024 posted an average SAT score of 1,078 with a 96% participation rate, meaning the score reflects nearly the entire graduating class rather than a self-selected subset, which makes it more meaningful than districts with low participation.

Homes inside Tomball ISD boundaries carry an estimated 18% premium over the greater Houston median. According to reAlpha's 2026 Texas school district analysis, the Tomball ISD median sits around $425,000, with annual property tax rates near 2.3%. For a $425,000 home, that translates to roughly $9,775 annually in school taxes, offset by homestead exemptions available under Texas Property Tax Code Sec. 11.13, which reduces taxable value by $100,000 for school district purposes as of 2023.

Boundary considerations: Tomball ISD's territory covers ZIP codes 77375, 77377, 77447, and 77433. Buyers in Cypress and Spring areas should verify whether a specific address falls within Tomball ISD or neighboring Cy-Fair ISD or Klein ISD, as boundaries split some subdivisions.

Friendswood and Pearland ISDs: South Corridor Overachievers

South of Houston, two districts have built A-level reputations that northwest-suburb buyers frequently overlook. Friendswood ISD earned a 92 out of 100 in 2025, every campus earned an A, and the average SAT was 1,105 with a 95% participation rate. Pearland ISD jumped from a B to an A, posting a district score of 91 and an average SAT of 1,158 across more than 20,000 students. Pearland's median home price is approximately $416,500 with ZIP code 77578 reaching $495,000.

Friendswood homes skew larger and older (median year built 1976, median lot 44,388 sq ft), while Pearland has newer master-planned communities like Shadow Creek Ranch ($440K) and Silverlake ($439K). Both districts fall inside Galveston County and Brazoria County appraisal jurisdictions, which carry historically lower assessed values per dollar than Harris County, providing modest tax relief compared to equivalent homes in Katy or Klein.

Katy ISD: The 97,000-Student Benchmark

Katy ISD sits in a category of its own among B-rated districts. Serving over 97,000 students across 74 campuses as of 2025, it is the third-largest district in Texas and has consistently earned A or B ratings for over a decade. The district encompasses nine four-year high schools, including Seven Lakes, Tompkins, Jordan, Mayde Creek, and Cinco Ranch, each with different feeder patterns and academic profiles.

The class of 2024 posted an average SAT of 1,089 with 91% of seniors tested. Graduation rates hover around 96%. Median home prices inside Katy ISD run approximately $395,000, with sub-communities like Cinco Ranch reaching $520,000-$650,000 and new master-planned areas near I-10 West sitting in the $380,000-$450,000 range. Buyers should note that Katy ISD crosses into Fort Bend County, Harris County, and Waller County, which means property tax bills differ by location even for homes attending the same schools.

Klein ISD and Cy-Fair ISD: The North/Northwest Volume Players

Klein ISD serves 51,200 students across 50 campuses in north Harris County. Klein High School earned a 92 from TEA in 2025, identical to Bellaire High School inside HISD. The district overall earned a B. Median home prices in the Klein corridor run around $350,000-$380,000, with areas near FM 2920 and Spring Cypress Road offering newer construction in the $400,000-$500,000 range.

Cy-Fair ISD (Cypress-Fairbanks ISD) is the largest district in Harris County and one of the largest in the state, serving 117,927 students in 2024-2025. The district maintained a B rating for the third consecutive year in 2025, scoring 85 out of 100 according to Community Impact reporting. No Cy-Fair campus received a D or F in 2025. Median homes in the Cy-Fair zone run $330,000-$380,000, with new construction in Bridgeland and Towne Lake pushing $450,000-$700,000.

HISD Exemplary Zones: Where a B-Rated District Hides A-Rated Campuses

Houston ISD earned a district-level B for 2025, up from near-failing status in 2023. The district now has 190 campuses (75%) rated A or B, with zero F-rated campuses compared to 54 in 2023. Three campuses warrant special attention:

Carnegie Vanguard High School - Ranked #5 in Texas, #42 nationally, and #1 in the Houston metro by U.S. News in 2025. Carnegie Vanguard is a magnet school requiring an application through the HISD School Choice office. Address proximity to the Midtown building does not guarantee admission.

Bellaire High School - A zoned high school earning a 92 (A) in 2025. Homes in the Bellaire HS attendance zone, covering much of the incorporated city of Bellaire and surrounding Meyerland neighborhoods, trade at a premium often exceeding $150,000 over comparable homes in other HISD zones. Verify any address against the HISD Attendance Zone lookup.

Memorial High School - Located in Spring Branch ISD (B-rated, distinct from HISD), Memorial posted an average SAT of 1,215 in the class of 2024. Spring Branch Academic Institute, also in SBISD, scored 1,478, the highest in the Houston metro.

Conroe ISD: Montgomery County's B-Rated Growth District

Conroe ISD is the seventh-largest district in Texas, serving approximately 73,000 students across 68 campuses in Montgomery County. The district earned a B in 2025, and the class of 2024 averaged 1,103 on the SAT with a 67% participation rate. Conroe ISD is the primary school district for The Woodlands, where established neighborhoods trade at $500,000-$900,000, while Lake Conroe-adjacent Conroe ISD addresses run $350,000-$600,000. The district adds over 2,000 students per year, with facility investment that affects long-term Montgomery County tax rates.

Texas School Finance and Robin Hood Recapture: What Buyers Need to Know

Texas school finance operates under the Robin Hood recapture system, formally called the Excess Local Revenue program administered by the Texas Education Agency. Districts with high property wealth per student send a portion of local tax revenue to the state for redistribution to property-poor districts.

For buyers, the key implication is that a high local tax rate does not always translate to richer school funding once recapture is applied. Fort Bend ISD has historically been a recapture district, and Katy ISD has approached that threshold during recent reassessment years. Ask your agent for the most recent ISD tax rate for any specific address rather than relying on the county rate alone.

Checking Attendance Zone Boundaries Before You Make an Offer

District-level ratings are a starting point. Campus-level ratings determine your child's actual school assignment and can differ dramatically within the same district. Bellaire High School (A, 92) and Lamar High School (B, 89) are both HISD flagships, yet a boundary line can place two homes on the same street in different feeder patterns.

Every ISD publishes an address lookup tool. Enter the exact property address into the boundary system before making an offer:

• Katy ISD: www.katyisd.org
• Klein ISD: www.kleinisd.net
• Cy-Fair ISD: www.cfisd.net
• Tomball ISD: www.tomballisd.net
• HISD: www.houstonisd.org
• Conroe ISD: www.conroeisd.net

Boundary redraws happen every few years and can shift a home into a different feeder pattern before a child reaches the relevant grade. Have your agent confirm the campus assignment in writing.

Frequently Asked Questions

Does buying in an A-rated district actually increase resale value?

Yes, and the effect is measurable. A Realtor.com analysis published in August 2025 found that homes in top-rated school districts consistently command premiums over comparable properties in lower-rated zones. In the Houston metro, A-rated districts like Tomball and Friendswood show premiums of 15-20% compared to the county median. This premium compresses slightly in strong seller markets and expands during corrections, making it a more reliable anchor than neighborhood amenities alone.

Can a family outside a district boundary attend by choice or transfer?

Texas law allows school districts to accept inter-district transfers, but acceptance is at the district's discretion and is never guaranteed. Some districts, particularly higher-rated ones in periods of growth, limit or close open-enrollment transfers when campuses reach capacity. Families who rely on a transfer rather than residing in the attendance zone have no guarantee of continued enrollment if the district closes transfers. For long-term planning, only a home address inside the target zone provides secure access to the assigned campus.

How often do TEA accountability ratings change?

Ratings are released annually each August, covering the prior academic year. Districts and campuses can move multiple letter grades in a single cycle, as HISD demonstrated by going from near-failing to a B-rated district between 2023 and 2025. The 2025 statewide data showed 24% of districts improved their grade. Buyers purchasing today will see at least one rating update before their child advances beyond kindergarten, so choosing a district with an upward trend is more defensible than chasing a single-year snapshot.

What is the difference between a magnet school and a zoned school in Houston ISD?

Zoned schools serve students whose home address falls within the campus attendance boundary; enrollment is automatic upon proof of residency. Magnet schools, including Carnegie Vanguard and DeBakey High School for Health Professions, accept students from across the district through a competitive application process that considers grades, test scores, essays, and sometimes auditions or portfolios. Living near a magnet campus does not guarantee admission. Acceptance rates at top magnets like Carnegie Vanguard can be competitive. The HISD School Choice office administers applications on a set calendar; missing the window typically means waiting another year.

How does the Robin Hood recapture system affect my school tax rate?

Recapture means that a portion of what you pay in school property taxes leaves your local district and goes to the state for redistribution. For buyers in high-value districts like Fort Bend ISD, this means local tax rates may not produce proportionally more local spending. The tax rate you pay is set by the school board; the portion that stays local depends on the district's wealth per student versus the state threshold. Check the current year's ISD tax rate (listed on your appraisal district notice) and ask the school district's finance office what share is subject to recapture for the current year.

What SAT participation rate matters when comparing districts?

A district with a 95% SAT participation rate and an average of 1,078 (Tomball ISD) is more impressive than a district with a 50% participation rate and a higher average, because the latter result reflects only the strongest students who self-selected to take the test. Friendswood ISD posted a 95% participation rate with an average of 1,105, making it one of the most statistically credible results in the metro. When comparing districts, always look at both the average score and the percentage of seniors tested, which TEA publishes alongside score data.

Find the Right District for Your Family and Your Investment

Choosing a home in the right Houston school district is one of the highest-return decisions a buyer can make. Tomball, Friendswood, Pearland, Katy, and the exemplary zones inside HISD and Spring Branch ISD each offer a distinct combination of academic performance, home price entry point, and long-term appreciation profile.
