Summary

South Cobb High School is a public high school located in Austell, Georgia, serving 2,137 students in grades 9-12. The school is part of the Cobb County School District, which is ranked 54 out of 206 districts in Georgia and has a 4-star rating from SchoolDigger.

While South Cobb High School is part of a relatively high-performing district, the school itself has consistently underperformed compared to the Cobb County and Georgia state averages on the Milestones Assessments. For example, in the 2024-2025 school year, the school's proficiency rates were significantly lower than the county and state in subjects like American Literature (34% vs 52.8% and 40.4%), Algebra I (27.3% vs 54.9% and 44.9%), and Biology (31.1% vs 55.2% and 44.2%). Additionally, the school's four-year graduation rates have fluctuated between 78.4% and 87.9% over the past few years, which is lower than the Cobb County average of 85.4%.

When comparing South Cobb High School to other Cobb County high schools, such as Hillgrove, McEachern, Campbell, and Pebblebrook, it is clear that South Cobb lags behind in academic performance, graduation rates, and student demographics. However, when compared to Marietta High School, which is in a different district (Marietta City), South Cobb High School outperforms some schools in the Atlanta Public Schools district, despite serving a student population with a similar socioeconomic status.

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
