End the practice of using GreatSchools rankings of public schools on Zillow.com, Realtor.com, Redfin.com, etc to influence homebuying decisions.  This practice supports systemic racism.  GreatSchools rankings are based on test scores.  Test scores indicate socioeconomic status of student populations more than anything else.  A school with low test scores is likely a school with a large population of lower income students.  Socioeconomic status is closely correlated to race/ethnicity.  Using rankings and labels to indicate that a neighborhood's schools are 'bad' or 'low performing' influences people to not buy a house in a particular neighborhood.  It influences them not to send their children to a public school, simply because it has a population of low-income students - reflected in lower test scores.  Many private schools have no GreatSchools data.  It also impacts how and where property tax dollars are collected and spent.  Resources often stay in privileged areas because homebuying trends are so entrenched. The use of this data is for 'consumer transparency', but it unintentionally reinforces systemic racism by influencing where people buy homes.
