How We Rank Schools
The rankings on The School Advocate are built around student performance data, weighted to reflect the subjects that matter most for long-term academic and career outcomes. English accounts for 40% of a school's overall score, Math accounts for another 40%, and Science makes up the remaining 20%. Each subject is scored by percentile, meaning a school's ranking reflects how it compares to every other school in the state — not just a raw test score in isolation. The result is a straightforward, comparable snapshot of academic performance that helps parents cut through the noise and focus on what the numbers actually show.
