Summary:
ZIP code 39455 (Lumberton, Mississippi) contains a single high school, Lumberton High School, which serves grades 7 through 12 and enrolls 268 students in the Lamar County School District. The school operates with a favorable student-teacher ratio of 8.1-to-1, but faces significant socioeconomic challenges, with 83.21% of students qualifying for free or reduced-price lunch. As the only high school in the area, all performance comparisons are made against the district and state rather than local peer schools.
Lumberton High School's state standing has collapsed in recent years. After earning 4 stars and ranking 66th out of 228 schools (71st percentile) in 2023-2024, it fell to 3 stars in 2024-2025 and then to 1 star in 2025-2026, ranking 184th out of 224 schools (18th percentile). The school's graduation rate is 77.3%, well below the Lamar County School District's rate of 91.2% and the state's 89.2%. Chronic absenteeism affects 32.2% of students, compared to 18.6% for the district and 23.9% for the state. Academically, Lumberton is below the state average in every tested subject. The largest gaps are in Biology End-of-Course (39.6% proficient vs. 63.1% statewide, a 23.5-point deficit), 8th grade Math (29.0% vs. 51.4%), and 8th grade Science (36.9% vs. 57.8%).
The most striking finding is that Lumberton High School is a severe outlier within its own district: Lamar County School District is rated 4 stars (78th percentile statewide), yet Lumberton trails the district by 33.3 points in Biology, 31.8 points in 8th grade math, and 25.9 points in 8th grade science. Some bright spots exist — 7th grade ELA, 7th grade math, and Algebra I all improved year-over-year — but these gains were overwhelmed by steep drops in English II (52.7% to 33.3%) and Biology (66.6% to 39.6%). The low student-teacher ratio of 8.1-to-1 suggests staffing is not the primary issue; rather, the school needs targeted interventions around chronic absenteeism, End-of-Course performance, and on-time graduation.
