Nearly 60 years have passed since the Supreme Court made its landmark Brown vs. Board of Education decision, legally ending school segregation across the U.S. Today, the legacy of school segregation persists, as racial isolation remains the reality of many students nationwide.

Though it is expected that the U.S. population will shift from a white-majority to a minority-majority by 2046, currently most students do not see that diversity reflected in their school experience. Nationally, according to the National Center for Education Statistics, 52 percent of black students and 58 percent of Latino students attend school where minority students make up 75 percent or more of the entire student body.

In Chicago, America’s most segregated city, it’s typical for students to go through their entire K-12 education without ever having met a classmate of another race, as “GOOD reported this week. In a recent radio interview on a local station, a Chicago student described having thought that schools were still legally segregated, based solely on her surroundings.

Advocates for reform argue that the incentives to foster greater diversity in schools are clear: Exposing students to racially and culturally diverse environments prepares them for the world outside school doors. Recent studies have also shown that students fare better academically in schools with greater levels of socioeconomic diversity.

Throughout the past decade, public school reformers have focused largely on building schools in the 90/90/90 model — schools with populations made up of more than 90 percent low-income students, more than 90 percent ethnic minorities and more than 90 percent students who meet set academic standards — as a way to provide high-performing schools to students in their own neighborhoods.

Some argue that the model fails to address issues of segregation, as discriminatory housing practices continue to create segregated communities — a fact that is especially problematic given that housing prices have been linked to school quality.

A recent study by the Brookings Institute reports that homes located in neighborhoods with high-performing schools cost, on average, about 2.4 times as much as those located in neighborhoods with low-performing schools. Since students of color are more likely to live in low-income neighborhoods than their white peers, students of color thereby have less access to high-performing schools.

Though redlining has long been part of the desegregation conversation, reformers are increasingly focusing their attention on charter schools — a model that has radically changed the landscape of the U.S. public school system in the last 30 years.

The popularity of charter schools has continued to escalate in recent years, despite the fact that charter schools have been found to be, on average, more segregated than traditional schools.

KIPP (the Knowledge is Power Program) is one of the most prominent examples of high-performing charter school networks, and includes more than 100 schools nationwide. KIPP’s program is designed to cater low-income students, and features a longer school day, a tough disciplinary structure and a curriculum aimed at catching students up to grade level. With an enrollment made up of 95 percent Latino or black students, KIPP’s focus is clearly to serve minority students.

What would the model for a urban charter school look like that would meet the needs of its students, while fostering a diverse student population?

This, among others, is a question reformers are tackling from coast to coast.
