A great quick and dirty source for test score data is on GreatSchools.org. They free resource that helps parents evaluate schools for their kids. They have a lot of great articles and resources on researching schools as well as general . What I like the most is that they actually provide tools to evaluate schools. GreatSchools.org allows users to bookmark schools that they are considering for an easy-to-retrieve list. Plus, they provide parents with maps, parent reviews, a school comparison tool, and school statistics like test scores, parent-teacher ratios, and ethnic breakdown.
