As nearly every school district in Tennessee prepares to bring students back to campus for in-person learning this year, the Tennessee Department of Education released guidance for safe school reopening Tuesday afternoon.

Education Commissioner Penny Schwinn said in a news conference Tuesday that 145 of the 147 school districts in the state have plans to open for in-person learning this year. Several districts have delayed reopening for one or two weeks to ensure adequate time to prepare to reopen safely.
