Summary:
Zip code 30047 in Lilburn, Georgia, is served by two large public high schools—Parkview High School and Berkmar High School—both part of Gwinnett County schools, together enrolling roughly 6,200 students in grades 9-12.
These two schools sit at opposite ends of the performance spectrum. Parkview is the clear standout, ranking in the 84th percentile statewide with a 4-star rating. It beats district and state averages in every subject tested—for example, 65.9% of its students are proficient in Algebra I versus 48.1% statewide, and its graduation rate of 88.7% tops both the district (85.4%) and state (87.2%). Berkmar, by contrast, ranks in the 28th percentile with a 1-star rating, and its proficiency rates are roughly half of Parkview’s in most subjects. Berkmar’s graduation rate (82.4%) trails Parkview by 6.3 points, though its dropout rate (2.2%) is actually better than the state average (2.4%).
The most striking difference is attendance: Berkmar’s chronic absenteeism rate is 41.9%—nearly double Parkview’s 21.1% and almost three times the district average of 15.0%. Notably, Berkmar receives more funding per student ($14,140 vs. $12,145) and has a better student-teacher ratio (14.8:1 vs. 18.6:1), yet its outcomes are far lower, suggesting resources alone don’t drive success. Both schools exceed the district’s chronic absenteeism average, and neither has shifted significantly in rankings over three years. For parents, Parkview offers consistently strong academics and graduation outcomes, while Berkmar faces serious challenges—particularly around attendance—that appear central to its lower performance. Addressing that 41.9% absenteeism rate could be the most impactful lever for improvement at Berkmar.
