Summary:
Zip code 30080 in Smyrna, Georgia, is served by one large public high school, Campbell High School, which enrolls 3,085 students in grades 9–12 as part of the Cobb County School District.
Campbell High School shows clear academic strengths in science and history, consistently outperforming the state average in both Biology and U.S. History. In the most recent data, 51% of students scored proficient in Biology versus 47.2% statewide, and 46.1% scored proficient in U.S. History versus 38.5% statewide. However, Algebra I remains a significant weakness, with only 37.2% proficiency compared to 48.1% statewide and 59.4% district-wide—a gap that has persisted across multiple years. The school’s overall state ranking has been somewhat volatile, peaking at 132nd (71st percentile, 4 stars) in 2024–2025 before slipping to 156th (66th percentile, 3 stars) in the latest release. Chronic absenteeism is a notable concern at 20.7%, well above the district’s 14.2% and the state’s 17.7%, which translates to roughly 640 students missing significant school time.
On the positive side, Campbell’s dropout rate of 1.9% is lower than both the district (2.3%) and state (2.4%), and its graduation rate of 86.9% slightly exceeds the state average of 87.2% while trailing the district’s 89.2%. With 52.12% of students qualifying for free/reduced lunch, the school serves a majority economically disadvantaged population, yet still manages to beat state averages in two core subjects. Per-student spending is $13,029 with a student-teacher ratio of 17.4:1. For parents, this school offers strong science and history instruction and solid student retention, but math proficiency and attendance are areas where targeted support could make a meaningful difference in overall outcomes.
