When parents are researching where to move, they typically look at the quality of a neighborhood's schools. But good data on that is hard to find. That's where a website called GreatSchools has thrived. GreatSchools rates almost every public school in America on a scale of 1 to 10. But when we analyzed those ratings, we found that they almost never give high scores to schools in poor neighborhoods — even though data from their own website shows that many of those schools do a good job teaching students.

EdWeek reported on how GreatSchools changed its ratings system in 2017: https://www.edweek.org/ew/articles/2017/11/01/school-rating-site-greatschools-expands-its-measuring-stick.html

And recently, researchers have found that the GreatSchools ratings may even have an effect on housing prices, locking poor people out of more affluent neighborhoods: https://www.chalkbeat.org/wp-content/uploads/2019/12/Digitization_and_Divergence__Paper_-2.pdf
