Some decent advice in the cdc guidelines.
In terms of scheduling, I’d like to see our high school embrace the cohorting ie that student and staff groupings are as static as possible by having the same group of children stay with the same staff (all day for young children, and as much as possible for older children). And limit mixing between groups if possible.
And,
Staggered Scheduling
Stagger arrival and drop-off times or locations by cohort or put in place other protocols to limit contact between cohorts and direct contact with parents as much as possible.
