Summary:
Zip code 30519 in Buford, Georgia, is served by two large public middle schools—Jones Middle School and Twin Rivers Middle School—both part of Gwinnett County and both educating students in grades 6 through 8 with enrollments around 1,700 students each.
Both schools are elite by state standards, ranking in the top 20% of all Georgia middle schools. Jones Middle School is the higher-performing of the two, ranking 69th in the state (88th percentile) with a 4-star rating, while Twin Rivers Middle School ranks 111th (81st percentile) with a 4-star rating. Both schools previously earned 5-star ratings, though each saw a slight decline in the most recent year. In nearly every subject, Jones outperforms Twin Rivers by a modest margin—typically 2 to 7 percentage points—but Twin Rivers actually matches or exceeds Jones in advanced coursework, achieving 100% proficiency in both Algebra I and Biology. Both schools dramatically outperform district and state averages in math, social studies, and advanced science, with proficiency rates often double the state average. The one notable exception is 8th Grade Physical Science, where both schools fall below the state average (Jones at 67.0%, Twin Rivers at 51.9%, state at 60.9%), a pattern also seen across the district.
Twin Rivers is particularly impressive given its demographics: 58.4% of its students qualify for free/reduced lunch compared to 43.6% at Jones, yet its scores remain close to Jones and it spends about $800 more per student ($13,232 vs. $12,425). Both schools have exceptionally low chronic absenteeism (6.6% at Jones, 8.2% at Twin Rivers) versus the district rate of 15.0% and state rate of 17.7%, which likely supports their strong outcomes. Families in this zip code have access to two high-quality middle school options that consistently rank among Georgia's best, with particular strengths in advanced math and science pathways and social studies.
