Cobb County


Summary:

The Cobb County school district in Georgia encompasses 110 schools, including 66 elementary schools, 26 middle schools, 17 high schools, and 1 alternative school. The district serves a diverse student population and has a mix of high-performing and lower-performing schools based on key metrics like test scores and graduation rates.

Some of the standout schools in the district include Walton High School, a high-performing public charter school that consistently ranks among the top high schools in Georgia, and Hillgrove High School, another top-performing high school that ranks in the top 50 in the state. At the elementary level, Timber Ridge Elementary School and Mount Bethel Elementary School are standouts, ranking in the top 20 elementary schools in Georgia.

While the district's overall 4-year graduation rate is above the state average at 85.4%, there is a wide range in academic performance across the schools. Some schools, like Walton High and Timber Ridge Elementary, have over 80% proficiency in core subjects, while others struggle with much lower proficiency rates. The data suggests that addressing these achievement gaps and replicating the success of the top-performing schools could help improve outcomes across the Cobb County district.
