Copy shortlink: A COVID-19 outbreak among bus drivers and transportation staff has forced Bloomington Public Schools to abruptly move elementary students back to distance learning, less than two weeks after schools reopened for in-person instruction. The district was one of many in Minnesota that began reopening elementary schools this month following a change in state guidelines. Now, it's the first in the metro area to reverse course because of widespread virus activity. The move comes as other large districts, including Minneapolis and St. Paul, are preparing to bring students back to classrooms and fielding significant safety concerns from teachers and their unions.
