Best Middle Schools in Zip Code 30126

Middle Schools in zip code 30126 (Mableton, GA) include three schools—Lindley Middle School, Floyd Middle School, and Betty Gray Middle School—serving grades 6–8 within Cobb County, a district ranked 58th in Georgia. All three schools serve predominantly economically disadvantaged populations, with 99–100% of students qualifying for free or reduced lunch.

These schools share similar overall state rankings (all in the 35th–45th percentile), but each has a distinct strength. Lindley Middle School is the largest (905 students) and made the biggest single-year jump, rising from 397th to 318th in state ranking—now the top-ranked school in this group. Floyd Middle School stands out for its exceptional Algebra I results, posting a perfect 100% proficiency rate in 2024-2025 and 94% in 2025-2026, far exceeding district (54.9%) and state (44.9%) averages. Betty Gray Middle School is the smallest (702 students) and shows the most consistent upward trajectory, improving its ranking three years in a row while also having the lowest chronic absenteeism rate (22.6%) of the three.

All three schools dramatically outperform on advanced coursework—Algebra I proficiency ranges from 90–96%, and 8th-grade HS Physical Science proficiency is 73–75%—yet struggle with grade-level math (23–34% proficiency) and social studies (22–31% proficiency). Chronic absenteeism is a major challenge, with rates between 22.6% and 29.7%, well above the district (14.2%) and state (17.7%) averages. Despite high per-student spending ($16,188–$16,674), proficiency in most core subjects remains below district averages. However, the strong advanced-course results show that these schools can achieve exceptional outcomes, and the recent year-over-year math gains—especially Lindley's 10–12 point improvements—suggest positive momentum worth watching.
