Summary:
Zip code 30106 in Austell, Georgia, is served by one public high school, South Cobb High School, part of the Cobb County School District, which enrolls 2,081 students in grades 9–12 and serves a predominantly low-income community, with 90.34% of students qualifying for free or reduced lunch.
South Cobb High School is showing positive momentum, improving its state ranking from the 53rd percentile in 2024–2025 to the 61st percentile in 2025–2026, a jump of 33 positions. The school earned 3 stars in each of the past three years. Most notably, the school posted dramatic year-over-year gains on End of Course Milestones tests: Algebra I proficiency rose from 27.3% to 37.4% and Biology from 31.1% to 40.7%, both outpacing district and state improvements. US History is a clear strength, with 50.6% of students proficient in 2025–2026, well above the state average of 38.5%. The graduation rate of 87.9% also exceeds the state average of 87.2%, which is commendable given the high poverty rate. Per-student spending is $15,348 with a student-teacher ratio of 15.8:1.
However, significant challenges remain. Chronic absenteeism is a critical concern at 26.9%, nearly double the district rate of 14.2% and well above the state rate of 17.7%, meaning roughly one in four students is missing substantial school time. The school also trails the district by 19–22 percentage points in Algebra I and Biology proficiency, a persistent achievement gap. The dropout rate of 2.9% is slightly above both district (2.3%) and state (2.4%) averages, translating to about 60 students annually. For parents, this school offers a supportive environment with improving academics and strong graduation support, but addressing attendance will be key to unlocking further gains and closing the gap in math and science.
