When schools began reopening last fall, New Jersey education officials received pages of guidelines on when to quarantine classrooms and close schools if as few as two students or teachers tested positive for COVID-19.
Within two weeks of the start of the 2020-2021 school year, at least 20 schools had sent students home and temporarily switched to remote learning due to positive cases in their classrooms.
This year, school districts may not be so quick to shut down.
