A new study out of Pittsburgh suggests that improving teacher quality across the board may be the surest way to close the racial achievement gap. The study, which looked at Pittsburgh students’ test scores over a two-year period, found that a student’s teacher was a better predictor of his or her performance than race. The scores varied widely depending on the teachers’ ranking, the study says, regardless of students’ race.
