“Whether students in 50/50 schools will continue to achieve at higher rates remains to be seen, but data shows that students in general perform better when they attend socioeconomically diverse schools. Academically, this may benefit low-income students the most. In a National Assessment of Educational Progress math test administered in 2017, low-income fourth graders in more affluent schools scored about two years ahead of low-income students in high-poverty schools. According to research by Reardon, at Stanford, segregation is one of the most potent contributors to ethnic achievement gaps.”

Stanford and USC Researchers launch new "Segregation Index" tool to track U.S. neighborhood and school segregation

The Segregation Index, launched May 2022, is a comprehensive resource for tracking neighborhood and school segregation in the U.S., across every neighborhood and school. The project shows that since the landmark Brown v. Board of Education decision, U.S. schools remain highly segregated by race/ethnicity and economic status, most segregation occurs between school districts (though segregation within districts has also increased over time), and segregation is growing in the nation’s largest districts.

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.

We may be living at a time when education should be readily available for everyone, but knowledge still appears to be hard to come by. A new research suggests that black and Latino students are still a few grade levels behind their white classmates.

Stanford University conducted an educational study on the test scores of around 40 million US students and discovered that students of color had lower scores than white students. In addition to that, the academic-achievement gap between white and colored students was even greater in wealthy university towns like Evanston in Illinois and Berkeley in California.
