Summary:
Zip code 30067 in Marietta, Georgia, is home to three elementary schools—Sope Creek Elementary School, Brumby Elementary School, and Powers Ferry Elementary School—serving roughly 2,542 students in Pre-K through 5th grade within the Cobb County School District.
These three schools offer vastly different educational experiences. Sope Creek Elementary is the clear standout, ranking 22nd in the state (98th percentile, 5 stars) and showing steady improvement over three years. Its math proficiency rates are exceptional—ranging from 83.1% in 3rd grade to 90.6% in 5th grade—far exceeding district and state averages. In contrast, Brumby Elementary (981st, 1 star) and Powers Ferry Elementary (1,084th, 1 star) struggle significantly, with 5th grade math proficiency at just 14.0% and 26.3%, respectively. Powers Ferry is also declining rapidly, dropping 243 state ranking positions in two years.
Socioeconomic factors and attendance appear closely tied to these outcomes. Sope Creek has only 9% of students on free/reduced lunch and a chronic absenteeism rate of 2.8%, while Brumby (78% free/reduced lunch, 25.7% absenteeism) and Powers Ferry (90% free/reduced lunch, 21.6% absenteeism) face far greater challenges. Interestingly, the lower-performing schools spend more per student (Brumby at $19,035 and Powers Ferry at $18,991 versus Sope Creek at $14,446) and have smaller class sizes, yet achievement remains far lower. For parents, this zip code presents a stark choice: Sope Creek delivers top-tier results, while Brumby and Powers Ferry demonstrate that additional funding and smaller classes alone haven't closed the achievement gap.
