Summary:
Zip code 30039 in Snellville, Georgia, is served by a single public high school, Shiloh High School, part of the Gwinnett County School District, which enrolls roughly 2,096 students in grades 9 through 12.
Shiloh High School is a large school with a student-teacher ratio of 15.7:1 and per-student spending of $13,221. The school has shown remarkable upward momentum, jumping from a state ranking of 318th (31st percentile) in 2023–2024 to 216th (53rd percentile) in 2025–2026, moving from a 2-star to a 3-star rating. Its graduation rate of 88.7% exceeds both the district (85.4%) and state (87.2%) averages, and its dropout rate of 1.9% is lower than both the district (2.8%) and state (2.4%). Academically, the school improved in every tested subject year-over-year, with Algebra I proficiency (48.8%) now matching the state average (48.1%) and representing a relative strength. However, Biology (37.9%) and American Literature (25.5%) proficiency lag state averages by 9.3 and 14.9 points, respectively, and the school still trails Gwinnett County averages in all subjects by roughly 5 to 13 points.
The most pressing concern is chronic absenteeism, which stands at 36.0%—more than double the state rate of 17.7% and 2.4 times the district rate of 15.0%. This is particularly striking given the school’s strong graduation rate and academic gains. With nearly 70% of students qualifying for free or reduced lunch, Shiloh High School faces significant socioeconomic challenges, yet it is outperforming expectations in graduation, dropout prevention, and Algebra I. The school appears to be on a positive trajectory, but addressing attendance and closing gaps in Biology and literacy will be essential to sustaining its progress and closing the remaining distance to district and state benchmarks.
