Summary:

Zip code 30078 in Snellville, Georgia is home to two public high schools—Brookwood High School and South Gwinnett High School—both serving grades 9-12 within the Gwinnett County School District, and together they enroll roughly 6,400 students.

These two schools offer vastly different educational experiences despite sharing the same district and zip code. Brookwood High School is the clear standout, earning a 4-star rating for three consecutive years and ranking in the top 13% of Georgia high schools. Its graduation rate is 94.1%, its dropout rate is just 0.6%, and its chronic absenteeism rate is 14.4%. On state Milestones tests, Brookwood posts proficiency rates of 62.6% in Algebra I, 60.4% in Biology, and 57.9% in U.S. History—all well above district and state averages. By contrast, South Gwinnett High School holds a 2-star rating and ranks in the 35th-39th percentile statewide. Its graduation rate is 88.4%, but its chronic absenteeism rate is a concerning 31.9%—more than double Brookwood's and nearly double the state average. South Gwinnett's test proficiency rates are roughly half of Brookwood's: 33.8% in Algebra I, 26.3% in Biology, and 38.6% in U.S. History.

The achievement gap between these schools is substantial, with Brookwood outperforming South Gwinnett by 19 to 34 percentage points on core subjects. Socioeconomic factors likely play a role, as 67% of South Gwinnett students qualify for free/reduced lunch compared to 40% at Brookwood. Interestingly, South Gwinnett actually spends more per student ($12,593 vs. $11,889) and has a slightly better student-teacher ratio (16.9:1 vs. 18.3:1), yet achieves far lower outcomes. Both schools have shown stable rankings over three years, suggesting entrenched patterns. For families in 30078, the choice between these two public high schools carries significant implications for academic outcomes, with Brookwood clearly leading in nearly every measurable category.
