Top 10 Houston-Area School Districts for 2026: 2025 TEA Ratings and Home Price Impact

Top 10 Houston-Area School Districts for 2026: 2025 TEA Ratings and Home Price Impact

Does the School District Really Change What You Pay for a House?

Short answer: yes, by a measurable amount. In greater Houston, two homes that are nearly identical in size and condition can carry price tags $50,000 to $150,000 apart if they sit on opposite sides of an ISD boundary. The Texas Education Agency releases A-F accountability ratings for every district and campus, and those scores are now one of the first filters buyers use on HAR before they ever schedule a showing. Understanding where each district stands and what that means for your mortgage budget is one of the highest-value research moves you can make in 2026.

TL;DR: Tomball ISD and Friendswood ISD lead the Houston metro with A ratings (scores of 92) in the 2025 TEA release. Pearland ISD jumped from a B to an A at 91. Katy ISD and most other large-district competitors landed at B. Median home prices inside top-rated ISDs range from roughly $350,000 in Katy to $725,000 in The Woodlands (Conroe ISD). Knowing these numbers before you make an offer could save or cost you six figures.

1. Tomball ISD: Highest-Scoring Large District in Texas

Tomball ISD earned an A with an overall accountability score of 92 in the 2025 TEA release on August 15, 2025, marking the sixth consecutive A for the district. It is the only large district (20,000-plus students) in Texas to hold an A rating and the only A-rated district in both Harris and Montgomery counties. Across all three TEA domains, every Tomball ISD high school earned straight A's.

Flagship high school: Tomball Memorial HS posted a 96 on the Student Achievement domain in 2025. The school competes in UIL Class 6A and has produced multiple state-qualifying academic and athletic programs. Advanced Placement participation and passing rates consistently outperform the state average, with the district's CCMR (College, Career, and Military Readiness) rate putting it among the top tier in Region 4.

Draw for buyers: The ISD spans Tomball proper and the Rosehill community. Ranch-style homes on larger lots and newer master-planned communities (Amira, Breckenridge Forest) attract buyers seeking suburban space without paying the Heights or Woodlands premium. Per Realtor.com data, the median listing price in Tomball hovers near $409,999 in mid-2026, with inventory around 1,000 active listings and a 53-day average days on market.

2. Friendswood ISD: Consistent A-Rated Performer in Galveston County

Friendswood ISD earned an A rating at 92 points in the 2025 accountability cycle, the same score as Tomball ISD and the highest mark the district has held since at least the 2021-22 school year. Every campus in the district earned an A, including Friendswood High School at 91 on Student Achievement.

Flagship high school: Friendswood High School competes in UIL 6A and has a long-running academic competition tradition. The school's AP passing rates and dual-enrollment participation are well above the state median, and its graduation rate consistently exceeds 97 percent. The district's STAAR passing rates in math and reading for grades 3-8 placed it at Performance Level 0 (meeting standards) across almost all indicators.

Draw for buyers: Friendswood is a tight-knit community tucked between Pearland and the Galveston Bay area. It is smaller in geographic footprint than most Houston-area ISDs, which keeps school sizes manageable. Per HAR data, the median sold price sits around $437,000 in early 2026, representing a slight softening from the 2024 peak but still reflecting the premium buyers pay for the A-rated district boundary.

3. Pearland ISD: The A-Rating Upgrade That Moved the Market

Pearland ISD made the most notable jump in the 2025 TEA cycle, climbing from a B to an A at 91 points. That one-letter improvement is consequential for buyers because it shifted the district from a "good" to an "excellent" designation at a time when Pearland's housing inventory was already tightening. The district scored 91 on Student Achievement, 82 on School Progress, and 91 on Closing the Gaps.

Flagship high school: Pearland ISD operates multiple 6A high schools including Pearland HS and Glenda Dawson HS. Dawson HS has been a perennial UIL academic team competitor and has earned multiple state-level academic challenge appearances. The district's CCMR rate and TSI (Texas Success Initiative) college readiness scores have tracked steadily upward over three years.

Draw for buyers: Pearland combines access to the Texas Medical Center (a roughly 20-minute drive to 288) with a suburban lifestyle and strong retail amenities along Broadway. Per HAR Pearland price trend data, the median sold price in April 2026 was $383,500 with 123 transactions and a brisk 16-day average days on market. The A-rating upgrade will likely keep that pace elevated through 2026.

4. Katy ISD: The Large-District Benchmark

Katy ISD received a B at 88 points in 2025, earning the highest score of the top 10 largest school districts in Texas for the third consecutive year. More than 60 Katy ISD campuses scored A's or B's. For a district serving more than 90,000 students across a sprawling geographic footprint from Cinco Ranch to Brookshire, the consistency of a top-B performance is remarkable.

Flagship high school: Seven Lakes HS stands out with a 96 on the TEA's 2025 Student Achievement domain, the highest score among Katy ISD high schools. Tompkins HS came in at 95 and Jordan HS at 94. Seven Lakes and Tompkins are UIL 6A programs with deep enrollment and competitive athletics and academics. AP program size and pass rates at Seven Lakes consistently rank among the top 10 percent of Texas high schools.

Draw for buyers: Katy ISD encompasses some of the most dynamic new-construction corridors in the metro, from the Cane Island master-planned community to the settled neighborhoods of Cinco Ranch. Per HAR Katy market data, the median sold price was $355,000 in April 2026, making it one of the most affordable entry points among the top-tier ISDs on this list.

5. Cy-Fair ISD: B-Rated with A-Caliber High Schools

Cypress-Fairbanks ISD (CFISD) maintained a B rating at 85 points in 2025, the third consecutive B, according to Community Impact reporting. No CFISD school received a D or F rating in 2025. The district's high school average was 87, above the district-wide average, and Bridgeland HS earned a 93 on Student Achievement alongside Cypress Woods HS at 94.

Flagship high school: Cypress Woods HS scored 94 overall and 90 on School Progress, making it one of the highest-rated 6A schools in the county. Bridgeland HS came in at 93. Both schools feed the growing master-planned communities in the Cypress ZIP codes (77433, 77429) and have robust dual-credit and AP offerings. Cy-Fair overall earned a "Superior Achievement" financial rating under School FIRST for the 23rd straight year, according to CFISD's own release.

Draw for buyers: Cy-Fair ISD is one of the largest ISDs in Texas by enrollment, offering buyers a wide geographic range from northwest Houston suburbs to newer Cypress developments. The median home price in the core Cy-Fair 77493 ZIP code was approximately $343,000 in early 2026 per HAR, while premium communities like Bridgeland push well above $500,000.

6. Klein ISD: College Readiness Leader at an Affordable Price Point

Klein ISD earned a B at 86 points in 2025, a steady climb from 80 in 2023 and 84 in 2024. More importantly for college-bound families, Klein ISD earned an A rating specifically in the CCMR (College, Career, and Military Readiness) component, reflecting the district's focus on post-graduation preparedness. All five Klein ISD high schools and all ten intermediate schools earned an A or B.

Flagship high school: Klein Oak HS scored 90 overall and an A on Student Achievement. Klein Collins HS and Klein High also participated in multiple UIL academic state competitions. The district reported 127 academic distinctions across campuses in 2025, a 37 percent increase since 2023.

Draw for buyers: Klein ISD spans the Spring/Klein area north of Houston, offering buyers access to FM 2920 and Highway 249 corridors. Home prices are among the more accessible in the top-rated group, with much of the district's inventory in the $300,000-$400,000 range.

7. Conroe ISD: The Woodlands Premium in a B-Rated District

Conroe ISD scored 85 in 2025, earning a B for both the 2023-24 and 2024-25 cycles, per Community Impact's coverage. Twenty-six of its 66 rated campuses earned an A, and the district holds the distinction of zero F-rated campuses.

Flagship high school: The Woodlands HS earned a 93 overall (A) and is one of the most recognized UIL 6A schools in Texas, with a history of state championships in academics and athletics. College Park HS scored 91. The combined AP enrollment and passing rates at Woodlands-area high schools consistently exceed state benchmarks.

Draw for buyers: The Conroe ISD boundary encompasses The Woodlands, which commands a substantial premium. Per multiple HAR market reports, the median sold price in The Woodlands reached approximately $725,000 in March 2026, with homes in the $600,000-$900,000 range moving fastest. Buyers seeking Conroe ISD at lower price points look to the Conroe city market, where prices are far more moderate.

8. Fort Bend ISD: Most Improved Among Large Districts

Fort Bend ISD improved from a C in 2023-24 to a B in 2024-25, per the district's own accountability page. Sixty-eight percent of FBISD campuses now hold an A or B, up from a smaller share the prior year. Twenty-four campuses earned an A (up from 18) and 30 earned a B (up from 24).

Flagship high school: Ridge Point HS in Missouri City scored 85 and serves the growing Sienna master-planned community. Fort Bend ISD's high school AP participation rates have climbed steadily over the past three years. The district's Sugar Land-area schools, including Dulles HS and Austin HS, serve one of the most diverse and academically competitive student populations in the state.

Draw for buyers: Sugar Land anchors the Fort Bend ISD premium tier. Per HAR Sugar Land price trend data, the median sold price in April 2026 was $460,000, with the listing market showing a median around $523,000. The district's rapid improvement from C to B should provide upward pressure on home values in its boundaries heading into 2027.

9. Clear Creek ISD: Consistent B with a Strong Bay Area Following

Clear Creek ISD scored 86 in 2025, the highest mark the district has recorded in at least four years, per Community Impact's Bay Area education coverage. The district improved in all three domains: student achievement rose to 85, school progress to 81, and closing the gaps to 87. All seven traditional high schools in the district earned an A or B.

Flagship high school: Clear Lake HS and Clear Springs HS are both recognized UIL 6A programs. Clear Lake HS has a long history of NASA-adjacent STEM programming reflecting its proximity to the Johnson Space Center community in League City. Dual-enrollment partnerships with San Jacinto College and college readiness metrics have been stable and above state averages.

Draw for buyers: The Clear Creek ISD footprint includes League City, Friendswood (the portion in Galveston County), Webster, and Clear Lake City. Home prices vary widely across this geography. The League City market sits at approximately $360,000 median in early 2026.

10. Magnolia ISD: Rising B-Rated District in Montgomery County

Magnolia ISD earned a B at 86 points in 2025, up from 84 in 2022-23, per Community Impact's Tomball-Magnolia coverage. Seven of the district's 16 campuses earned an A, seven earned a B, and two earned a C. In a Tomball-adjacent market, Magnolia ISD gives buyers access to Montgomery County's rural-suburban lifestyle at a meaningful discount to Tomball ISD boundaries.

Flagship high school: Magnolia West HS scored an 89 on the TEA's overall 2025 rating. Magnolia HS itself earned an 87. Both schools compete in UIL 6A and have growing athletic programs. The district outperformed the state in 58 of 60 TEA data points, per official district communications.

Draw for buyers: The Magnolia market sits near FM 1488, with homes primarily in the $300,000-$380,000 range. Buyers get the benefit of Montgomery County's relatively lower tax rates, a fast-growing community, and a B-rated district without the Tomball ISD price premium.

Why ISD Boundaries Can Swing Home Values by $50,000-$150,000

School district boundaries are drawn without regard for appraisal equity, and that creates price cliffs visible on any HAR heat map. Here is a real-world example that illustrates the gap.

The Spring TX / Klein ISD Boundary Example: In the Spring area north of Houston, homes on the Cypress-side of Cypresswood Drive can fall in either Klein ISD or Spring ISD, depending on their exact address. Spring ISD earned a D rating in 2025 with a significantly lower score than Klein ISD's B/86. Two homes built in the same decade, with the same square footage and lot size, routinely show a $60,000-$100,000 spread at listing, with the Klein ISD home commanding the premium. Buyers who cross the street to save $80,000 on the purchase price often find that same differential baked into resale values when they go to sell.

The same dynamic plays out at the Conroe ISD / Magnolia ISD boundary along FM 2978, at the Fort Bend ISD / Lamar CISD line in Fulshear-area communities, and at various Katy ISD edge streets abutting lower-rated districts to the east.

What drives the gap? It is not exclusively academic performance. Buyers weight perceived safety, extracurricular offerings, the social network of the school community, and resale predictability. When a district earns an A, buyers pay a forward-looking premium based on the expectation that the A will hold. When a district improves from C to B as Fort Bend ISD did, the market often prices in further improvement before it actually happens.

For a buyer placing 5 percent down on a $400,000 home in a B-rated district, crossing into an A-rated boundary might mean a $450,000 purchase and $2,500 more at closing. Over a seven-year hold, if the A-rated home appreciates an additional 1.5 percent annually above the B-rated home (a conservative estimate given historical HAR data), the net wealth difference exceeds the upfront premium.

College Readiness, STAAR, and What the TEA Rating Actually Measures

The TEA A-F rating is built on three domains. Student Achievement (roughly 70 percent weight on overall score) covers STAAR passing rates, CCMR metrics, and graduation rates. School Progress covers year-over-year growth and relative performance. Closing the Gaps measures how the district serves historically underperformed student groups.

For buyers focused on college readiness, CCMR is the most direct metric. A student earns CCMR credit by achieving a qualifying score on the SAT or ACT, earning a dual-credit college hour, achieving TSI college-readiness status, or completing an approved Industry-Based Certification. Tomball ISD, Klein ISD, and Pearland ISD all rank above state averages on CCMR percentage in the 2025 cycle.

STAAR passing rates vary by campus more than by district. In Katy ISD, for example, Cinco Ranch-area elementaries often post rates 15-20 points above the district average, while entry-corridor campuses closer to I-10 track closer to the state mean. Buyers should search specific campus ratings at TXschools.gov before finalizing a neighborhood.

Frequently Asked Questions

Can the TEA rating for a district change quickly enough to affect my home value during a typical ownership period?

Yes, and the change can go in either direction. Fort Bend ISD moved from C to B in a single cycle. Conversely, districts that lose state oversight performance thresholds can slip a letter grade within two years. A five-to-seven-year ownership horizon carries meaningful rating-change risk in mid-tier districts. Monitoring TXschools.gov annually is part of responsible homeownership in Texas.

Does buying in a B-rated ISD instead of an A-rated ISD produce a dramatically worse educational outcome for children?

Not necessarily. Individual campus scores within a B-rated district can match or exceed A-rated campuses in neighboring districts. Klein ISD is B-rated overall but earned an A specifically on the CCMR measure, meaning its graduates enter college or careers at high rates. A buyer who picks a specific campus with an A within a B-rated district may get the best of both worlds: better affordability on the purchase and a strong school for the child.

How do UIL athletic programs factor into home values near specific high schools?

UIL athletic prestige (playoff appearances, state championships, stadium quality) affects desirability and local community identity, both of which influence prices. Seven Lakes HS, The Woodlands HS, and Katy HS all have strong athletic traditions that generate genuine community engagement. For some buyers, proximity to a UIL playoff-level program is a positive amenity similar to proximity to a park or retail center.

Are homes inside The Woodlands community always inside Conroe ISD?

Almost entirely, yes. The Woodlands master-planned community falls overwhelmingly within Conroe ISD boundaries. A very small portion of the southernmost sections of The Woodlands touches Tomball ISD or Spring ISD boundaries. Any buyer targeting a specific address should verify the ISD on HCAD.org or MCAD (Montgomery County Appraisal District) before writing an offer.

What is the difference between the district-level TEA rating and a campus-level rating?

The district rating aggregates all campus scores, so a district with strong elementaries but weaker high schools may land at a B overall even though the high school is a C. The reverse is also possible. Buyers with children at specific grade levels should look at the campus-level score at TXschools.gov rather than relying solely on the district letter grade when making their ISD decision.

Find the Right ISD Boundary Before You Make an Offer

Buying inside the right school district boundary is one of the most durable forms of home value protection available in Texas. A strong TEA rating supports appreciation, draws motivated neighbors, and often correlates with better-maintained infrastructure. Buying blindly and discovering the ISD boundary after closing is a costly surprise this market does not forgive.
