Study Finds Parents’ Online School Reviews Correlated with Test Scores and Demographics, Not School Effectiveness

A first-of-its-kind analysis of parents’ reviews of U.S. public K–12 schools, posted primarily from 2009 to 2019 on the popular school information site GreatSchools.org, found that most reviews were written by parents at schools in affluent neighborhoods and provided information that correlated strongly with test scores, a measure that closely tracks race and family income. Language associated with school effectiveness, which measures how much students improve in their test scores over time and is less correlated with demographics, was much less used.
