Title I and federal lunch eligibility offer another window into the student body: 55.2% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 9% below the Georgia average and 7% above the national baseline. The school offers 17 Advanced Placement courses, a stronger academic pipeline indicator than enrollment alone. Counselor coverage works out to roughly 347 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 31.0% according to the 2021-22 Civil Rights Data Collection.
