How We Rank Schools
Our rankings are based on student academic performance across three core subjects, using state assessment data. We weight English at 40%, Math at 40%, and Science at 20% to calculate each school's overall percentile score. Percentile scores reflect how a school performs relative to all other public high schools in Georgia — so a school in the 97th percentile is outperforming 97% of schools statewide. We focus on outcomes because we believe student performance data is the most direct, comparable measure of academic quality available to parents.
