Both black and Latino students do better academically when they attend integrated schools, and white students’ academic performance doesn’t suffer when their classmates are black and brown. Socioeconomics plays a key role in that outcome: Integrated schools in middle-class and affluent areas tend to be better resourced. They are more likely to have experienced teachers, well-educated parents, and high academic expectations than segregated schools in low-income communities. Tracking test scores, graduation rates, and college success can help us validate the impact of that.
