DeKalb County School District

The DeKalb County School District (DCSD) is a school district headquartered at 1701 Mountain Industrial Boulevard in unincorporated DeKalb County, Georgia, United States, near Stone Mountain and in the Atlanta metropolitan area. DCSD operates public schools in areas of DeKalb County that are not within the city limits of Atlanta and Decatur. It served a portion of Atlanta annexed by that city in 2018 until 2024, when that portion was re-assigned to Atlanta Public Schools (APS).

The school district is overseen by the seven-member DeKalb County Board of Education. The superintendent/CEO is, as of June 8, 2024, Dr. Devon Q. Horton. The system educates more than 102,000 students at 138 schools with more than 14,000 full-time employees and 6,000 teachers. In 2018, the school system graduated over 5,800 students from high school.

The district includes three of the top-ranked schools in the nation in 2018 according to U.S. News & World Report. The DeKalb School of the Arts earned a gold designation after being ranked No. 75 overall, and No. 2 in Georgia. Chamblee Charter High School also earned a gold designation, ranking No. 457 nationwide and No. 14 in Georgia. The Arabia Mountain High School Academy of Engineering-Medicine performed well enough to earn a silver designation, ranking No. 58 in Georgia.
