The CT school year is 180 days. 10% of that is missing only 18 days of school per year. Figure that a lot of families will take 3-5 days off for vacations, a kid will be sick twice during the year requiring 2-3 days off each, throw in a funeral or two for 2 days off, a mental health day or two, and about 2 days worth of half-days for Dr./Dentist appointments and you’re already at the 10% mark. Covid just pushes that over the edge.
