Largest Public Schools in Louisville, KY

By the Public School Stats Editorial Team · Last updated: October 2026

The largest public schools located in Louisville, Kentucky, ranked by enrollment in the 2023–24 NCES Common Core of Data, with lunch-eligibility figures for each campus.

Public schools physically located in Louisville enrolled 86,549 students in the 2023–24 school year across 160 campuses with reported enrollment. City pages answer a different question from district pages: a district is a governing agency that can span many cities, while this page groups individual campuses by the city in their CCD location address. The distinction matters in metros like Louisville, where one district may run most campuses but charter and neighboring-district schools also sit inside city limits. Every figure here is a campus figure from the school-level CCD files, labeled 2023–24.

The 15 largest schools in Louisville

The largest campus, Ballard High, enrolled 2,033 students — 2.3% of all students in schools located in the city. Large comprehensive high schools dominate the top of most city rankings because elementary schools are deliberately kept small and neighborhood-based, while high schools consolidate whole districts into a few campuses. Where a very large campus is a virtual or alternative school, its CCD school type says so in the source file, and readers should weigh that before comparing it with a traditional campus.

Reading the lunch-eligibility column

Across the 15 largest Louisville campuses that reported lunch counts, 54.9% of students were eligible for free or reduced-price lunch in 2023–24.

Eligibility is a family-income measure collected through the National School Lunch Program and reported to NCES by each school. Campuses marked n/r did not report a usable count — in some cases because the school serves all meals free under the Community Eligibility Provision and reports through a different route. The column is therefore best read campus by campus, and the aggregate above is computed only over reporting campuses, which the text states openly rather than burying in a footnote.

How city totals relate to district totals

If you add the campuses here, the sum will not match any single district’s enrollment, and it is not supposed to: district totals count every student a district serves wherever the campus sits, while this page counts every student in campuses located in Louisville whichever district runs them. For agency-level figures — staffing, spending and diplomas — use the district pages in the district index or the Kentucky state pages for statewide totals. Both views come from the same 2023–24 CCD files; they simply group the same schools two different ways.
