Summary:

Zip code 30106 in Austell, Georgia, is served by six schools in the Cobb County School District, including three elementary schools, two middle schools, and one high school, all of which serve predominantly low-income student populations.

Cooper Middle School is the standout performer in this area, earning a 4-star rating and ranking in the 70th percentile statewide. Despite 91.7% of its students qualifying for free/reduced lunch, Cooper achieves perfect 100% proficiency on the Algebra I End of Course exam and exceeds district averages in both 8th-grade science (44.8% vs. 35.8%) and social studies (60.9% vs. 52.3%). By contrast, Garrett Middle School struggles significantly, ranking in the 37th percentile with just 22% social studies proficiency and a 20.4% chronic absenteeism rate. South Cobb High School, the area's only high school, shows positive momentum with its state ranking improving from 211th to 178th, a graduation rate of 87.9% (above the state average), and U.S. History proficiency of 50.6% that exceeds the state by 12 points. However, its 26.9% chronic absenteeism rate is nearly double the district average.

Among the elementary schools, Clarkdale Elementary leads in 3rd-grade math (54% proficiency) but shows a concerning 12.4-point decline by 5th grade. Sanders Elementary and Austell Elementary both trail district averages across most subjects. Notably, both middle schools excel at accelerating advanced students—Garrett's Algebra I proficiency jumped from 75% to 95.4% year-over-year—even as grade-level math scores remain below district norms. Per-student spending shows an inverse relationship with outcomes: Austell Elementary spends the most ($21,767) yet ranks lowest, while Cooper Middle spends the least ($14,423) and achieves the best results. The most actionable takeaway is that Cooper's success despite similar demographics to its peers offers a potential blueprint, while addressing chronic absenteeism—especially at South Cobb High—represents the clearest opportunity for systemic improvement.
