Summary:

Mableton, Georgia is served by three middle schools—Lindley Middle School, Floyd Middle School, and Betty Gray Middle School—all part of the Cobb County School District, serving grades 6-8 with enrollments ranging from 702 to 905 students.

These schools share a similar profile: nearly all students qualify for free or reduced lunch, and per-student spending is consistent (roughly $16,200-$16,700). However, performance varies. Lindley Middle School is the standout improver, jumping 79 spots in state rankings to 318th (45th percentile) and posting the strongest 6th-grade math scores (32.4% proficient). Floyd Middle School excels in advanced coursework, with a perfect 100% Algebra I proficiency rate in 2024-2025 and the best 8th-grade math scores (47.2%). Betty Gray Middle School is the most consistent, maintaining a stable ranking around the 36th percentile and boasting the lowest chronic absenteeism (22.6%). All three schools rank in the bottom half of Georgia middle schools, with 2-star ratings.

Chronic absenteeism is a systemic challenge, with rates (22.6%-29.7%) nearly double the district average of 14.2%. Social studies is a universal weakness, with proficiency (22.3%-30.6%) far below the district's 52.3%. The most striking finding is the "Algebra I paradox": all three schools achieve 90%+ proficiency in Algebra I, yet only 23-33% of students are proficient in grade-level math—a much wider gap than the district's. Encouragingly, all schools showed meaningful year-over-year math improvements, especially Lindley (6th grade up 10.6 points). Betty Gray has a specific concern in 8th-grade science (17.5% vs. 29.7% state), while Floyd showed the strongest prior-year ELA scores, which may support its advanced math success.
