Summary:
Zip code 30519 in Buford, GA is served by one large high school, Seckinger High School, part of the Gwinnett County School District, which enrolls 2,318 students in grades 9-12.
Seckinger High School is a top-quartile performer in Georgia, currently ranked 93rd statewide (80th percentile) with a 4-star rating. Its most impressive statistic is a 97.4% graduation rate—more than 12 points above the district average and 10 points above the state. The school excels in Biology, with 59.6% of students proficient in 2025-2026, outpacing the district by 9 points and the state by over 12 points. U.S. History proficiency (45%) also beats both district and state averages. However, Algebra I is a relative weakness: at 52.4% proficiency, it trails the district by 5.2 points, and it dropped nearly 9 points year-over-year—a steeper decline than the district or state experienced. With 44% of students qualifying for free/reduced lunch, the school achieves strong outcomes despite moderate economic challenges, and its per-student spending of $12,034 with an 18.2:1 student-teacher ratio reflects efficient resource use.
One area of concern is chronic absenteeism, which sits at 17.5%—higher than the district's 15.0% and nearly matching the state's 17.7%. This is somewhat paradoxical given the school's high graduation rate and strong test scores, suggesting the school may have effective strategies to keep students on track despite attendance challenges. Additionally, test scores declined across all subjects from 2024-2025 to 2025-2026 (Algebra I -8.9 points, Biology -5.1 points, U.S. History -3.6 points), mirroring broader district and state trends. The school's state ranking has also been volatile, improving from 66th to 57th, then falling to 93rd. While the school remains above state averages in every subject, families should watch whether these declines represent a temporary dip or a longer trend, particularly in math.
