Summary

South Cobb High School in Austell, GA, serves approximately 2,081 students in grades 9-12 as part of the Cobb County School District. The school has shown meaningful improvement in recent years, climbing from the 44th percentile statewide in 2021-2022 to the 61st percentile in 2025-2026, and earning a 3-star rating after several years at 2 stars. This progress is especially notable because the school serves a predominantly economically disadvantaged population—90.34% of students qualify for free or reduced lunch, up sharply from 67% just two years prior—yet academic outcomes have continued to rise.

South Cobb’s strongest differentiator is its performance with historically underserved student groups. The school ranks in the 77th percentile statewide for African American students (earning a 4-star rating) and also performs well with Hispanic students (68th percentile) and Special Education students (67th percentile). U.S. History is a consistent strength, with 50.6% of students scoring proficient in 2025-2026 compared to the state average of 38.5%—a 12.1 percentage point advantage that even exceeds nearby Marietta High School (38.6%) and Campbell High School (46.1%). The school also posted the largest single-year gain in Algebra I among nearby schools, jumping from 27.3% to 37.4% proficiency, and improved Biology scores from 31.1% to 40.7%.

The graduation rate surged from 78.4% in 2023-2024 to 87.9% in 2024-2025—now above the state average (87.2%) and far ahead of peer schools with similar demographics, such as Osborne High School (78.9%) and Pebblebrook High School (75.7%). Chronic absenteeism remains a challenge at 26.9%, nearly double the district rate, though it has improved from 30.2% in 2021-2022. Spending efficiency is another plus: at $15,348 per student, South Cobb spends less than Marietta High School ($16,079) and dramatically less than Atlanta Public Schools alternatives like B.E.S.T Academy ($43,336), while achieving comparable or better outcomes. With rising test scores, a surging graduation rate, and strong subgroup performance, South Cobb is on a positive trajectory worth watching.

South Cobb lacks in many areas. They really need to get better trained highly qualified Teachers that will not walk out because they can not control their classes. That being said they need to also get better control of that campus and the kids who are out of control. Sex and drugs abound on this campus and you would think they would be striving to put a stop to that as well. Not to mention all the violence and fighting and there are some serious thieves at this school. South Cobb is not a school that if I had known what I know now after having had 2 kids in this school one who is finishing and one just starting,I would have ever sent my kids to. I am seriously considering when I move soon moving into a totally different district. I WARN all Parents right now, South Cobb is a horrible environment!!!! Close Quote
