Anoka-Hennepin students must now mask up if their school logs an unusually high rate of absences and the county they live in registers more than 50 infections per 10,000 residents.
That's the upshot of a new policy the school board approved 5-1 Monday for Minnesota's largest district, which sets building-level criteria for mask mandates as opposed to the district-wide approach decision-makers have taken since the start of the academic year.
In addition to community spread of COVID-19, the district's new policy will also consider student absences in triggering a mask mandate for pupils in kindergarten and above. It also calls for educators in all Anoka-Hennepin early childhood education centers to mask up universally.
Superintendent David Law said district officials adopted the attendance metric as a rough stand-in for building-level COVID infections, noting about 90% of student absences so far this year were due to illness.
Parents have been clamoring for the district to take school-level data into account when setting mask policy, Law said.
And because infections can take days or even weeks to appear in the Minnesota Department of Health's official tallies, Anoka-Hennepin officials were left to approximate as best they could with the attendance data.
"We were put in an awkward spot of trying to make decisions with data that doesn't exist," Law told the board.
The new policy goes into effect Jan. 31. And while it sets new standards for building-level mask mandates, the updated guidance is missing any mention of what conditions, if any, would trigger a return to remote learning for students in the state's largest district.
