The E.T.S. researchers took four variables that are beyond the control of schools: The percentage of children living with one parent; the percentage of eighth graders absent from school at least three times a month; the percentage of children 5 or younger whose parents read to them daily, and the percentage of eighth graders who watch five or more hours of TV a day. Using just those four variables, the researchers were able to predict each state’s results on the federal eighth-grade reading test with impressive accuracy.
“Together, these four factors account for about two-thirds of the large differences among states,” the report said.
