Understanding the 10/10 Rating
SchoolDistrictFinder rates Williamson County Schools 10 out of 10 — top-tier among Tennessee public school districts. Our ratings are based on state assessment results — the share of students scoring proficient or above in reading and math, as reported in Tennessee’s TCAP assessments (2025–26 school year). We average each district’s reading and math proficiency, then rank it against other districts in the same state to produce a 1–10 score. Because Tennessee is compared only against itself, the rating reflects how this district performs relative to its in-state peers.
