That figure sits 24% above the Georgia state mean of 14.5:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 13% higher, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 8.7% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 86% below the Georgia average and 83% below the national baseline. The school offers 28 Advanced Placement courses, a stronger academic pipeline indicator than enrollment alone. Counselor coverage works out to roughly 337 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 20.5% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Fulton County spends $15,569 per pupil district-wide, below the Georgia average of $15,679 and below the national average of $19,490.
