It looks like they go off campus for it, leaving the non-participating students behind on campus. I am a retired teacher in a very conservative area, and I don't remember anything like this.
Years ago we were allowed to spend time memorizing verses for summer camp, but they stopped that in the 60s I think. This surprised me.

A school board in Staunton, Va., has said children in its district may continue the tradition of leaving school for weekly Bible classes despite complaints from some parents that students who choose to stay behind are disadvantaged.In a 5-1 decision Feb. 14, board members ruled that the weekday Bible classes attended by more than 80 percent of the district's first-, second- and third-graders will be allowed for the remainder of the current school year but the issue will be revisited for next year.
The voluntary 30-minute classes came under fire from some parents who said their children were missing out on valuable instruction time during the period they waited for their classmates to return, according to The Washington Post. Besides the idle time, students who opted not to attend Bible classes were stigmatized, parents said.
Staunton, part of Virginia's Shenandoah Valley, is along a corridor of Interstate 81 known as the state's Bible Belt.
The school district is one of about 20 in the region that release public school students from classes during the school day for religious instruction at nearby churches, The Post said...."
