An overview of Mandeville public schools
The federal directory lists 14 public schools in Mandeville, LA: 5 elementary, 6 middle, 3 high. The 14 schools that reported 2024–25 membership enrolled 10,064 students, an average of 719 per school. The largest campus is Mandeville High School (2,006 students), and the largest elementary school is Pontchartrain Elementary School (636).

Across schools that reported staffing, the median student–teacher ratio is 12.6:1, lower than the statewide school median of 13.3:1. A ratio counts classroom-teacher FTE against total enrollment, so specialized programs and part-time staffing can move it; ask schools for actual class sizes by grade.
Among 3 high and combined schools with 2021–22 civil-rights data, 3 reported students enrolled in AP courses and 2 of 3 reported computer-science classes. Confirm current course catalogs directly with each school.
About 28% of students in reporting schools were eligible for free or reduced-price meals in 2024–25. This describes the community served; it is not a quality signal, and community-eligibility schools can report differently.
