Ratings are on scale of 1 (below average) and to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider needs as part of the school selection process.
