Tens of thousands of students have left Florida’s public schools in recent years amid an explosive expansion in school choice. Now, districts large and small are grappling with the harsh financial realities of empty seats in aging classrooms.

As some districts are being forced to close schools, administrators are facing another long-avoided reckoning: how to integrate students in buildings that remain racially and economically segregated.

In the Florida panhandle, one tiny district plans to consolidate its last three stand-alone elementary schools into one campus because there aren’t enough students to cover the costs of keeping the doors open. But the Madison County School District’s decision to do so has exposed tensions around race in a community where for years some white families have resisted integrating public schools.

“It’s the elephant in the room that nobody wants to talk about,” county school board member Katie Knight told The Associated Press.
