Summary:

The Cobb County, Marietta City, and Department of Juvenile Justice districts serve 58 schools in the Marietta, Georgia area, covering elementary through high school grades for roughly 43,000 students.

Families in this area will find a dramatic range of school experiences. The top tier is anchored by Marietta Center for Advanced Academics, ranked #4 in the state with 94-99% math proficiency and the lowest chronic absenteeism rate (1.9%) in the dataset. West Side Elementary School has climbed to #9 statewide, while Dickerson Middle School (#5) and Walton High School (#8) round out the elite options. A cluster of East Cobb schools—including Lassiter High School, Pope High School, Dodgen Middle School, and Mount Bethel Elementary School—consistently ranks in the 90th+ percentile with graduation rates above 97%. At the other end, Powers Ferry Elementary School (11th percentile), Hollydale Elementary School (15th percentile), and Smitha Middle School (27th percentile) struggle significantly, with math proficiency often below 25%.

The strongest predictor of success here is economic status: schools with 90%+ free/reduced lunch populations score 30-50 points lower than affluent counterparts, regardless of spending. LaBelle Elementary School spends the most per student ($24,614) yet ranks in the 27th percentile, while Walton High School spends the least ($12,373) and ranks 98th. Chronic absenteeism is a critical issue at Marietta High School (33.4%) and Osborne High School (30.9%), nearly double the state average. Encouragingly, Fair Oaks Elementary School jumped 22 percentile points and Dunleith Elementary School improved 24 points, showing that targeted interventions can move the needle. Note that middle school Algebra I scores (87-100% proficiency) reflect only advanced students, not school-wide performance. ELA scores for 2025-2026 release in December.
