Summary:
Zip code 30068, located in the Marietta area of Cobb County, Georgia, is served by one large public high school, Wheeler High School, which enrolls 2,401 students in grades 9 through 12 within the Cobb County School District.
Wheeler High School shows a mix of strengths and challenges. The school’s Biology proficiency is a clear bright spot, outperforming the state average by 8–12 percentage points in recent years and even exceeding the district average in 2024–2025. Graduation and dropout rates are also positive, with an 89.4% graduation rate and a 2.1% dropout rate, both better than district and state averages. However, the school has seen a steady decline in its state ranking, falling from the 83rd percentile in 2023–2024 to the 65th percentile in 2025–2026, and its star rating dropped from 4 to 3 stars. Algebra I proficiency remains a persistent challenge, sitting 12–18 percentage points below the district average, and U.S. History proficiency fell sharply from 49.0% to 35.4% year-over-year. Chronic absenteeism is a major concern at 22.7%, well above the district’s 14.2% and the state’s 17.7%, which may be contributing to the academic declines.
For parents, Wheeler High School offers strong science instruction and good student persistence, but the school is struggling in foundational math and social studies courses. With nearly half of students qualifying for free or reduced-price lunch, the school serves a diverse population, and its per-student spending of $13,905 is notable, though the student-to-teacher ratio of 16.3:1 is relatively high. The declining ranking and elevated absenteeism suggest that targeted interventions in Algebra I, U.S. History, and attendance could help reverse the downward trend and close the gap with the Cobb County district average.
