The location of high quality schools can be seen from the map, which presents a surface generated from the Report Card 2000 test score results of elementary schools. The color blue indicates the areas with the best elementary schools—the darker the blue the better the schools—while red indicates areas with below average elementary schools. Rutherford County departs from the pattern of Sumner, Wilson, and Williamson counties: in those counties, the best schools are located close to the Davidson county line, the zone most attractive to commuters working in Davidson County; in Rutherford County, the best schools are located deep in the county, in areas less accessible to commuters. The clear inference is that school quality must be relatively unimportant to those households choosing to migrate from Davidson County to northeastern Rutherford County.
