Baltimore County Public Schools officials want to bring students back to classrooms in the second semester. But with just one month to go, it remains unclear if the county’s COVID-19 positivity rate will throw that plan off course. At a recent school board meeting, board member Russ Kuehn pressed School Superintendent Darryl Williams on when school officials will make a decision about students returning. “There is going to be a go, no go decision day, right?” Kuehn asked Williams. “I would guess that would be a week or so out, if not two weeks out.” Williams told Kuehn he could not give him a specific date because reentry is going to be based on when the rate of COVID-19 cases in the county declines to an acceptable level.
