Decatur High School is a comprehensive public high school located in Decatur, Georgia, an urban community of 20,000 residents situated approximately five miles east of downtown Atlanta. Decatur is part of an independent school district within DeKalb County and serves about 5000 students.

DHS is an IB World School in which all students participate in the IB Middle Years Program. The school offers both the IB Diploma Program and the IB Career Program for 11th/12th graders. All of these IB courses are two-year courses, so many of our students will take college-level IB exams at the end of the senior year, rather than separate exams at the end of the junior and senior years.
