The GreatSchools rating is a simple tool for parents to compare schools based on test scores. It compares schools across the state, where the highest rated schools in the state are designated as “Above Average” and the lowest “Below Average.” It is designed to be a starting point to help parents make baseline comparisons. We always advise parents to visit the school and consider other information on school performance and programs, as well as consider their child's and family's needs as part of the school selection process.
SchoolGrades.org uses a rigorous, common standard to compare schools across the United States. It adjusts for differences in academic standards across the states and accounts for each school’s unique economic profile. School letter grades are based on how well students perform based on an international standard of excellence.
