My son is starting kindergarten next year. So I was pleased to discover GreatSchools, a site that provides data on test scores, teacher-student ratios, enrollment numbers, etc. There are also parent reviews of each school. For instance, here GreatSchools’ list of Fairfax County Public Schools and my son’s likely school, Hayfield Elementary.
Some data points need to be taken with a grain of salt — elementary-age test scores in particular. But my sampling of parent reviews found them to be well-written and the site is well-organized and easy to navigate.
