When students return to school in New Albany, Ohio, in August, they’ll be carefully watched as they wander through red-brick buildings and across well-kept lawns—and not only by teachers.

The school district, with five schools and 4,800 students, plans to test a system that would require each student to wear an electronic beacon to track their location to within a few feet. The technology logs which students and teachers are in each classroom throughout the day. The hope is such technology could prevent or minimize an outbreak of Covid-19, the deadly respiratory disease at the center of a global pandemic.
