Summary

Mandeville Junior High School in Mandeville, LA, is a high-performing public school serving 510 students in grades 7 and 8, part of the highly-rated St. Tammany Parish school district.

This school is an academic powerhouse, earning a 5-star rating from SchoolDigger for ten consecutive years and consistently ranking among the top 5-9% of middle schools in Louisiana. Its students significantly outperform state averages, with recent proficiency rates of 82% in Math, 89% in ELA, and 84% in Social Studies—20 to 29 percentage points above the state. Compared to nearby junior highs like William Pitcher Junior High School and L.P. Monteleone Junior High School, Mandeville leads in Math and Social Studies. The school also boasts the lowest chronic absenteeism rate among comparable area junior highs, at 16.5%, versus rates above 21% at schools like Fontainebleau Junior High School and William Pitcher Junior High School. A low student-teacher ratio of 11.1 supports personalized learning.

A standout strength is Mandeville’s exceptional support for Special Education students, ranking in the 98th percentile statewide for three consecutive years—a unique achievement among nearby schools. The school benefits from a strong feeder pattern of top-performing elementary schools like Tchefuncte Middle School and Lake Harbor Middle School, creating a pipeline of well-prepared students. While the school shows a typical "8th-grade math dip" seen across the district, it manages this decline better than peers. One area for attention is the volatility in support for African American students, which has dropped from the 91st to the 53rd percentile over recent years, contrasting with the school’s overall stability.
