Thousands of black students have returned to the classroom in the past few months. Distance learning has been disastrous, especially for many black children, and data has shown that students are falling behind in key subjects. This could undermine decades of work by local school districts and the federal government to close the performance gap between black and white students.

In interviews, some parents said they had no choice but to bring their children back to classrooms so they could work. Others said they couldn’t take it any longer if their children struggled with online learning.

Charles Johnson, a Brooklyn parent, allowed his son to return to personal high school classes last fall after his son requested. He then attended a day of class before the city closed high schools indefinitely.

“He hates distance learning, oh my god, he hates it,” said Mr. Johnson. But Mr Johnson, who suffers from diabetes and other health problems, said he would not consider sending his child back. The risk feels too great.

“As bad as I want the schools to open,” he said, “I don’t want him in these classrooms.”

Also, in many cities and counties, Latin American and Asian American families are less likely than white families to send their children back. Asian-Americans have opted out of in-person tuition with the highest rates of any ethnic group in New York City. Latino families in Chicago most likely said they would keep their children at home when schools reopened.

Still, the pattern is most consistent and pronounced among black families, who have been particularly hard hit by decades of segregation, divestment, and racism. By one estimate, a $ 23 billion gap, or $ 2,226 per student, separates funding from predominantly white and non-white districts, and Indiana University Bloomington sociologist who studied the reopening, Jessica Calarco, said the pandemic said the pandemic have increased this inequality.
