The data we use to develop our school rankings and ratings are from each state’s annual No Child Left Behind Test scores, from each state’s Department of Education, and from the National Assessment of Educational Progress data, found within the National Center for Education Statistics. Additional details on educational environment, school enrollment, groups by ethnicity/ancestry or economic groups, and school funding, are brought together from the National Center for Education Statistics.

Our state-specific school quality ratings and nationally-comparable school quality ratings are built in-house using a patented algorithm that's exclusive to NeighborhoodScout.
