Classes in Carson City schools resume August 24th with about 80-percent of the students on a hybrid schedule bringing each to campus two days a week. Seating in classrooms will be socially distanced and everyone will be wearing masks. What students won’t see is how those desks and chairs have been treated. First with a special coating, called a bio-layer. The treatment lasts 90 days in additions to a normal process cleaning system twice a week.
