What to Know About Schools in Flower Mound, TX for 2026

Flower Mound sits primarily in Denton County, with a small section spilling into Tarrant County. If you're weighing the pros and cons of living in Flower Mound, TX, the local education system is probably already on your list of things to sort out - and for good reason, since school zones directly affect which neighborhoods make sense for your search and how your daily commute plays out.

The market moves fast. Homes are spending roughly 22 days on the market, the median sale price is sitting around $690,000, and with only 255 homes available as of mid-2026, you don't have the luxury of circling back on a property once you've figured out the school situation. Better to know the landscape before you start touring.

Flower Mound School Districts at a Glance

Most of the town falls under two main public systems: Lewisville Independent School District (LISD) and Argyle Independent School District (AISD). Smaller sections are served by Denton, Grapevine-Colleyville, and Northwest Independent School Districts.

According to 2026 data from the National Center for Education Statistics (NCES), there are 19 public schools in the town serving approximately 16,894 students. Before you make an offer, confirm your specific property address with the relevant district - don't rely on a neighbor's zone or what the listing says.

District Ratings and Academic Scores

Many buyers consult third-party platforms like GreatSchools or NeighborhoodScout for test scores and overall ratings. These sites pull state-level data from the Texas Education Agency to assign scores to individual campuses.

The catch is that school quality metrics vary depending on which source you're using. Looking at the Texas Education Agency's own reports gives you a cleaner read on graduation rates and standardized test performance across Lewisville ISD and Argyle ISD, rather than a single number that may be weighting factors you don't care about.

Finding Top-Rated Educational Options

There's no single official ranking of the best schools in Flower Mound, TX. Families tend to lean on aggregate platforms like GreatSchools and NeighborhoodScout to compare academic performance, equity, and student progress metrics across the region.

These platforms update their methodologies regularly, so a school's score can shift from one year to the next. Use the ratings as a starting point, not the whole story.

Understanding School Ratings

GreatSchools and NeighborhoodScout both pull from state assessments, but they weigh factors differently. A high score on one site might be driven by test scores; the other might prioritize year-over-year student growth. They're not measuring the same thing.

Read the methodology pages. Better yet, visit the campus or pull the district's own published accountability reports. A number without context doesn't tell you much.

Public Schools and Attendance Boundaries

Five different school districts serve parts of Flower Mound. Knowing where the boundary lines actually fall is your first real task as a buyer. Lewisville ISD covers the majority of the town, but the dividing lines between LISD and Argyle ISD can weave through individual neighborhoods in ways that aren't obvious from a map.

School boundaries also shift. Population growth and new housing developments can trigger redraws, so don't assume a home zones to a specific school just because the street next to it does.

Mapping Your Home to a School

The most reliable check is using the official boundary lookup tools on the Lewisville ISD and Argyle ISD websites. You enter a specific address and it tells you the zoned elementary, middle, and high school.

If a property sits near a district line, call the district directly. Listing descriptions get outdated, and finding out you're in the wrong zone after closing is exactly the kind of surprise nobody wants.

High School Campuses and Athletics

The public high schools located in or serving the town include Flower Mound High School and Marcus High School, both part of Lewisville ISD, along with Argyle High School, part of Argyle ISD.

Athletics carry real weight here. Edward S. Marcus High School is home to the Marauders, who play their home football games at Marcus High School Marauder Stadium at 5707 Morriss Road.

High School Football and Facilities

Flower Mound High School fields the Jaguars. In the summer of 2025, the school completed a $4.2 million stadium upgrade funded by a 2024 bond measure.

These facilities tend to double as community gathering spots once fall arrives. If a specific program or athletic conference alignment matters to you, verify it directly through the Texas Education Agency or the district's athletic department - those things can change.

Primary and Middle School Options

The 19 public schools in the area include numerous elementary and middle school campuses spread across the various districts serving the town. The younger grade levels are distributed throughout, which means your elementary assignment isn't always in the same corner of town as the high school your child will eventually attend.

As students move from elementary to middle school, their assigned campus follows the district's feeder pattern - multiple elementary schools feeding into a single middle school, which eventually flows into one of the area high schools.

Feeder Patterns and Transitions

Feeder patterns in growing areas shift when new schools open or boundaries get redrawn. Lewisville ISD and Argyle ISD both publish their current feeder alignments on their official websites.

If you're thinking long-term about where your kids will land in middle and high school, confirm those paths directly with the district. Third-party real estate portals aren't always current.

Private, Charter, and Specialized Schools

Beyond public options, the area has 14 private schools serving roughly 2,037 students in 2026. Local charter options like Founders Classical Academy also operate in the region.

Coram Deo Academy runs a campus in Flower Mound, offering a Christian, classical, and collaborative university-model preK-12 education. Private costs vary widely - there's no centralized published average for the town - but as a reference point, Temple Christian Academy lists tuition at roughly $6,410 per year.

Private School Tuition and Enrollment

Contact private and charter schools directly for current tuition rates, application deadlines, and waitlist policies. Many of these institutions require enrollment steps well ahead of the academic year, and waiting until spring to start that process is usually too late.

Factoring Schools Into Your Relocation

School district taxes show up in your monthly housing costs, so they're part of your budget math. Lewisville ISD adopted an overall tax rate of $1.1178 per $100 valuation for the 2024-2025 fiscal year, and that rate held for the 2025-2026 fiscal year as well.

That context matters, especially since roughly 28% of homes in the area are currently selling above list price. Build the specific district's tax rate into your mortgage calculations before you fall in love with a number.

Finding Official District Information

The Town of Flower Mound's website links to the various independent school districts - a practical starting point when you're trying to organize your research in one place.

Stick to official municipal and district pages for tax rates and boundary data. You want current numbers, not whatever an aggregator last cached.

Calendars and District Contact Information

Each of the five districts serving Flower Mound runs its own academic calendar - separate start dates, holidays, and teacher in-service days. There's no unified schedule across all of them.

For those in Lewisville ISD, the district can be reached at (469) 713-5200. The mailing address is P.O. Box 217, Lewisville, TX 75067.

Weather Closings and Schedule Updates

When winter weather hits or an emergency comes up, districts announce closings and delays through their official websites and local media. Sign up for your specific district's text or email alerts as soon as you enroll - don't rely on finding out through social media.

If you need to transfer records, contact your assigned campus directly. Central registrar contacts vary by district, so there's no single number that covers everyone.
