Summary:

The St. Tammany Parish school district in Louisiana is a high-performing district, ranked 18th out of 116 districts in the state, and includes 55 public schools serving elementary, middle, and high school students across communities like Mandeville, Slidell, and Covington.

The data reveals a clear "Mandeville Advantage," with schools in that area consistently dominating the top rankings. Mandeville High School is the standout high school, ranking 15th in the state with the highest graduation rate (90%) and lowest dropout rate (0.9%). Fontainebleau High School is a remarkable turnaround story, jumping from a 3-star to a 5-star school in just two years. Among elementary and middle schools, Pontchartrain Elementary School leads the parish with a 96th percentile state ranking and exceptionally low chronic absenteeism (6.4%), while Tchefuncte Middle School posts outstanding test scores (90% Math, 89% ELA). In contrast, Salmen High School faces significant challenges as the lowest-ranked high school, with a high dropout rate (5.3%) and low graduation rate (76.4%). Alton Elementary School is the lowest-ranked school overall, with the lowest test scores in the dataset (40% Math, 54% ELA).

A critical finding is the strong correlation between socioeconomic status and performance, as schools with the highest free/reduced lunch rates consistently have the lowest test scores and highest chronic absenteeism. For example, Glynn H. Brock Elementary School has a 78.84% free/reduced lunch rate and very low math proficiency (39%). Chronic absenteeism is a major issue for struggling schools, with Pearl River High School (36.3%) and Little Pearl Elementary School (35.8%) having rates over 35%. The district average for chronic absenteeism (21.2%) is slightly better than the state average, but the disparity between top and struggling schools is stark. Algebra I proficiency also serves as a key indicator, with high-performing schools like Northshore High School (82%) far outpacing lower-ranked schools like Slidell High School (61%).
