Summary:
Zip code 31558, encompassing Saint Marys, Georgia, is served by a single middle school—Saint Marys Middle School—which educates students in grades 6 through 8 as part of the highly rated Camden County School District, a 5-star district ranked 11th out of 201 in the state.
Saint Marys Middle School consistently ranks in the top 20% of Georgia middle schools, holding a 4-star rating for three consecutive years (81st percentile in 2025–2026). Its standout strength is advanced math: 100% of students taking Algebra I scored proficient or above in both 2024–2025 and 2025–2026, more than double the state average of 48.1%. Science performance is equally impressive, with 8th-grade science proficiency at 51.4% (state: 29.7%) and HS Physical Science at 97.9% (state: 60.9%). The school also exceeds state averages in 6th, 7th, and 8th-grade math, as well as social studies (56% vs. 40.2% statewide). However, 8th-grade math proficiency declined notably year-over-year from 69.9% to 60.5%, and 7th-grade math dipped slightly, suggesting a need for targeted support in upper-grade math.
With 1,077 students and a student-teacher ratio of 15.3:1, the school serves a moderate-income population (47.54% free/reduced lunch) and spends $10,528 per student. A key concern is chronic absenteeism at 23.7%, significantly higher than the state average of 17.7%, though slightly better than the district's 24.8%. The school outperforms its district in most subjects, including Algebra I, 7th and 8th-grade math, science, social studies, and physical science, with only a slight lag in 6th-grade math (43.7% vs. 44.7%). Overall, Saint Marys Middle School offers exceptional advanced coursework and STEM instruction, making it a strong choice for families, though addressing absenteeism and the 8th-grade math decline would further strengthen its profile.
