Summary:
Zip code 31520 in Brunswick, Georgia, is served by two large public high schools—Brunswick High School and Glynn Academy—both part of the Glynn County School District, together educating roughly 3,862 students in grades 9-12.
These two schools offer distinctly different academic profiles despite similar size and funding. Glynn Academy is the higher performer, consistently ranking in the top 10% of Georgia high schools (51st of 455 in 2025-2026) and posting proficiency rates well above state averages in every subject—most notably US History (72.1% vs. 38.5% state) and Biology (74.6% vs. 47.2% state). Brunswick High School is a solid, improving option, climbing from 104th to 78th in state rankings over two years and also exceeding state averages in Biology and US History. However, Brunswick High trails Glynn Academy by roughly 8-16 percentage points across subjects, and its Algebra I proficiency (45.4%) falls below the state average (48.1%). Both schools post exceptional graduation rates—99.8% at Brunswick High and 98.4% at Glynn Academy—far exceeding the 87.2% state average.
The most significant difference between the two schools is economic: 90.98% of Brunswick High students qualify for free or reduced lunch versus 62.38% at Glynn Academy. This correlates with attendance patterns, as Brunswick High's chronic absenteeism rate (20.3%) exceeds both the district (15.0%) and state (17.7%), while Glynn Academy's rate (12.8%) is well below both. Despite these challenges, Brunswick High's near-perfect graduation rate demonstrates strong student support. For parents, Glynn Academy offers the strongest test scores and attendance, while Brunswick High delivers remarkable graduation outcomes and steady improvement despite serving a higher-need population. Both schools outperform their district in most subjects, making either a viable choice depending on priorities.
