Schools in Katy
Katy Independent School District is the area's defining public asset -- Niche has ranked it the #1 school district in the Houston area for five consecutive years -- but the Texas Education Agency's own 2025-26 state accountability system rates the district a more modest 'B' (88 out of 100), a real and worth-disclosing tension between two legitimate, differently-methodology'd sources.

Learn moreNiche's read: #1 in Houston, five years running
Katy ISD topped Niche's 2026 Best School Districts ranking for the Houston area for a fifth consecutive year, earning an overall A+ rating and leading categories including best place to teach, best teachers, and best school district for athletes, per Niche's rankings and Katy ISD's own reporting. Statewide, Niche ranks Katy ISD #10 in Texas -- but among the nine districts ranked ahead of it, none serves more than 22,000 students and five serve fewer than 10,000, meaning Katy ISD (serving nearly 97,000 students) is effectively the top-performing large district in the state by this measure.
The TEA's own accountability read: a solid but more modest 'B'
The Texas Education Agency's 2025-26 A-F state accountability system rates Katy ISD a 'B' overall, scoring 88 out of 100 possible points -- the same rating as the prior year. This is a genuinely different picture than Niche's #1-in-Houston, A+ framing: both are real, current, and named sources, and the honest read is that they measure different things (Niche aggregates parent/student reviews, test-score data, and other factors into a composite; the TEA grade is a specific state accountability formula tied to STAAR performance, growth, and closing achievement gaps). Neither cancels the other out.
A large, geographically expansive district -- confirm your specific zoned school
Katy ISD serves nearly 97,000 students across a footprint larger than the small incorporated City of Katy itself, including portions of Houston, Fulshear, and unincorporated Harris, Fort Bend, and Waller counties -- several of the master-planned communities covered in best-areas (Cinco Ranch, Cross Creek Ranch, Firethorne) are zoned to Katy ISD schools even though they sit outside city limits or in a different county. Given the district's size, individual school quality and specific attendance zones vary meaningfully by address; confirm a property's exact zoned elementary, middle, and high school directly with Katy ISD before buying or leasing rather than assuming district-wide reputation applies uniformly.
Key takeaways
- Niche ranked Katy ISD the #1 school district in the Houston area for a fifth consecutive year (2026 rankings), with an overall A+ rating; statewide it ranks #10 in Texas, but is effectively the top large district given the smaller enrollment of the districts ranked above it.
- The Texas Education Agency's own 2025-26 state accountability system rates Katy ISD a 'B' (88/100) -- a real, sourced, more modest read that sits in genuine tension with Niche's #1/A+ framing; both are disclosed rather than reconciled into one number.
- Katy ISD serves nearly 97,000 students across a footprint larger than the City of Katy itself, including parts of Houston, Fulshear, and all three surrounding counties -- several major master-planned communities outside city limits are zoned to Katy ISD.
- Given the district's size, always confirm a specific property's zoned elementary/middle/high school directly with Katy ISD rather than assuming district-wide reputation applies uniformly to every address.
