As the second-largest school system in Georgia and the 26th-largest in the United States, the Cobb County School District educates more than 106,000 students through programs at 114 schools across the county. The schools include 69 elementary schools, 25 middle schools and 16 high schools, along with two special education centers, an adult education center and a performance learning center for students at risk of dropping out of school.

The school district employs more than 14,000 people, about 5,900 of whom are classroom teachers. These staffing numbers make the Cobb County School District the largest employer in the county.

A seven-member Board of Education, elected by districts to four-year terms, approves policy and direction of the school district. For day-to-day operations, the board appoints a school superintendent.

Michael Hinojosa serves as the Cobb County School District superintendent.
