A clear socioeconomic divide emerges, with higher-performing schools like Camp Creek Elementary School (89th percentile) and Arcado Elementary School (86th percentile) serving lower poverty populations, while Lilburn Elementary School (89% free/reduced lunch) and Hopkins Elementary School struggle with proficiency rates well below district averages. Notably, per-student spending does not predict success—Lilburn Elementary School spends the most ($16,156) yet ranks in the 43rd percentile, while Parkview High School spends the least ($12,145) and ranks in the 84th.
