High Schools in Cobb County

Summary:

The Cobb County school district in Georgia is home to 17 public high schools, serving a diverse student population across a range of academic performance levels. While the district maintains a consistent 85.4% graduation rate, there are stark disparities in test scores and other key metrics among the schools.

The top-performing high schools in Cobb County include Walton High School, ranked 9th in the state, as well as Hillgrove High School, Harrison High School, and Pope High School, all of which are ranked in the top 25 in Georgia. These schools demonstrate exceptional academic performance, with 60-80% proficiency in core subjects and relatively low free/reduced lunch rates, indicating they serve more advantaged student populations.

In contrast, schools like Osborne High School, Pebblebrook High School, and South Cobb High School struggle academically, with proficiency rates often below 40%. These lower-performing schools tend to have higher free/reduced lunch rates, suggesting a correlation between socioeconomic factors and student outcomes. Addressing these disparities in the Cobb County school district will be crucial to ensuring equitable educational opportunities for all students.
