Summary:
Zip code 30907, covering the Martinez area of Georgia, is home to a single middle school, Stallings Island Middle School, which serves grades 6 through 8 with an enrollment of 729 students as part of the highly rated Columbia County School District.
Stallings Island Middle School is an elite institution, maintaining a 5-star rating for three consecutive years and ranking in the top 8% of all Georgia middle schools (44th out of 578 in the 2025–2026 school year). Its mathematics program is a clear standout, with proficiency rates exceeding state averages by 26 to 37 percentage points across all grade levels. The school also excels in Algebra I acceleration, with 78.9% of students scoring proficient or above on the End of Course exam—a remarkable 30.8 points above the state average and a 5.4-point improvement from the prior year. Beyond academics, the school boasts a chronic absenteeism rate of just 7.7%, less than half the state average of 17.7%, which likely contributes to its consistent success. With only 24.69% of students receiving free/reduced lunch, the school serves a relatively affluent population, and its per-student spending of $11,286 appears efficient given the strong outcomes.
While the overall picture is strongly positive, there are a couple of minor concerns worth noting. The school’s state ranking has slipped slightly from 23rd in 2023–2024 to 44th in 2025–2026, though it remains firmly in the top tier. Additionally, 8th-grade math proficiency dipped by 3.9 points year-over-year (from 76.4% to 72.5%), though this may be partially explained by higher-achieving students taking Algebra I instead. Physical Science performance, while strong at 75.7% proficiency, shows a smaller advantage over the state (+14.8 points) compared to other subjects, suggesting a potential area for growth. Overall, Stallings Island Middle School offers an academically rigorous environment with exceptional math instruction, strong attendance, and a track record of high achievement that makes it an excellent choice for families in the 30907 area.
