Denton ISD vs. Lewisville ISD: What Buyers Should Actually Know
Both districts get asked about constantly by relocating families — and the honest answer is that they’re closer than most “best school district” lists let on.
I get this question almost every week from families relocating to Denton County: “Should we buy in Denton ISD or Lewisville ISD?” The honest answer, based on the Texas Education Agency’s most recent accountability ratings, is that neither district is running away with it. Lewisville ISD earned a B (81 points) for 2024–25, and Denton ISD earned a B (80 points) after climbing up from a C rating in 2023. One point separates them at the district level — which means the decision usually comes down to specific campuses, feeder patterns, and what your family actually needs, not a blanket “District X is better” answer.

What Actually Differs
| Metric | Denton ISD | Lewisville ISD |
|---|---|---|
| 2024–25 TEA Rating | B (80/100) | B (81/100) |
| Trend | Improving — up from a C (78) in 2023 | Stable — third straight year scoring in the 80s |
| Standout Campuses | Varies by campus — worth reviewing individual ratings for your attendance zone | Flower Mound High School and Marcus High School both earned “A” grades |
| 4-Year Graduation Rate | Available by campus on the TEA website | 95.5%, above the 90.3% state average |
| Avg. Teacher Experience | Available by campus on the TEA website | 12.2 years, above the 11.1-year state average |
Ratings and figures reflect district-wide and campus-level data reported by the Texas Education Agency and local news coverage (Cross Timbers Gazette, Star Local Media, Denton Record-Chronicle) for the 2024–25 school year. Individual campus ratings within both districts vary — the district-wide grade is a starting point, not the full picture.

Not by a meaningful margin at the district level — Lewisville ISD’s 81 and Denton ISD’s 80 are one point apart in the 2024–25 TEA ratings, both earning a “B.” The more useful question is which specific campus serves the home you’re considering, since performance varies more by school than by district.

How do I find out which district serves a specific home?
Boundary lines can split neighborhoods and even streets in Denton County, so the address matters more than the city name. I check exact school zoning for every listing I send a family before we ever schedule a showing.
