Summary:
Zip code 30078 in Snellville, GA, is home to just one middle school, Snellville Middle School, which serves grades 6–8 and enrolls 820 students in Gwinnett County Public Schools.
Snellville Middle School presents a striking contrast in academic performance. Students enrolled in high school-level End of Course (EOC) exams achieve exceptional results: 85.4% proficiency in Algebra I and 94.0% in Biology, both far exceeding district and state averages by 30–45 percentage points. However, students in standard grade-level courses struggle significantly. Only 24.8% of 6th graders, 27.2% of 7th graders, and 32.6% of 8th graders are proficient in math—roughly 20–25 points below district averages. The 8th-grade physical science score of 32.8% is particularly concerning, sitting 28 points below the state average of 60.9%. This suggests a highly selective advanced-track program serves a small group of high achievers while the majority of students face substantial challenges with grade-level content.
Despite high poverty levels (75.85% free/reduced lunch eligibility), the school posts a chronic absenteeism rate of 13.9%, better than both the district (15.0%) and state (17.7%). Year-over-year improvements were seen in most subjects, including a 14.9-point jump in Algebra I and a 6.1-point gain in 8th-grade social studies. However, the school's state ranking has declined from the 49th percentile in 2023–2024 to the 31st percentile in 2025–2026, indicating peer schools are improving faster. With per-student spending of $14,833, the school has resources, but the wide gap between advanced and standard course outcomes suggests that scaling successful advanced-course strategies to the broader student population could be the most promising path forward for raising overall achievement.
