Largest School Districts in Texas 2026: Enrollment Rankings & Charts
Texas traditional public school districts are ranked by 2024–25 enrollment in the Texas Education Agency statewide summary. The 2026 title identifies the publication update; the ranked values retain their official source year.
Open-enrollment charter districts are excluded so the comparison uses one governance category. District totals include students assigned to district-operated virtual campuses, which can extend beyond the district’s local attendance area.
Texas District Enrollment Statistics
Statewide totals use district rows with charter status marked “No” in the same official file.

Enrollment movement and reporting scope
- 13 of the 50 districts recorded an increase, while 37 recorded a decrease.
- Prosper ISD posted the largest numerical gain in the group, adding 3,183 students.
- Houston ISD recorded the largest numerical decline, down 7,564 students.
- District totals can include students assigned to statewide virtual campuses; the district name does not always identify every student’s place of residence.
District Size and Statewide Enrollment Concentration
These modules use all 1,020 traditional districts, not only the 50 in the ranking.
| Enrollment band | Districts | Students | State share | Median |
|---|---|---|---|---|
| 100,000 or more | 3 | 433,473 | 8.5% | 139,776 |
| 50,000–99,999 | 12 | 823,996 | 16.2% | 67,668 |
| 25,000–49,999 | 36 | 1,330,369 | 26.1% | 34,638 |
| 10,000–24,999 | 67 | 1,058,710 | 20.8% | 13,777 |
| 5,000–9,999 | 74 | 537,303 | 10.5% | 7,060 |
| 1,000–4,999 | 318 | 694,262 | 13.6% | 1,830 |
| Under 1,000 | 510 | 216,505 | 4.2% | 377 |
Small-district count and large-system scale
- 510 districts enroll fewer than 1,000 students, yet together account for only 4.2% of traditional-district enrollment.
- The 25,000–49,999 band holds the largest student share at 26.1%, spread across 36 districts.
- The three districts above 100,000 students account for 8.5% of the statewide total.
Metropolitan Scale, Virtual Enrollment, and District Boundaries
Enrollment rank measures system size under the selected reporting rules. It does not measure school quality or the number of children living inside a city.
City limits and district lines differ
Houston, Dallas, Austin, Fort Worth, and San Antonio contain or border several independent districts. A city population total cannot be substituted for an ISD enrollment total.
Virtual campuses can reshape a position
TEA district totals include students assigned to district-operated virtual campuses. Statewide online programs can raise reported enrollment beyond the scale suggested by nearby residential development.
Campus count is administrative
The campus column counts distinct campus rows. It can include alternative and virtual campuses and should not be read as average class size or building capacity.
ISD and CISD share one scope
Independent School District and Consolidated Independent School District names both fall within the traditional-district category when the TEA charter field is “No.”
Charter systems need a separate ranking
Open-enrollment charter districts can operate campuses across multiple communities under a different governance model. Excluding them keeps the comparison focused on traditional local systems.
Rank is not an outcome measure
Graduation, attendance, staffing, finance, student need, and academic results require separate indicators and may vary among campuses in the same district.

The title year is the publication update. Counts are whole numbers; shares and changes are rounded to one decimal place.
The ranked figures are official 2024–25 values, not 2025–26 estimates. Enrollment, campus count, charter status, and prior-year change remain on one statewide-summary basis.
