Opening schools too quickly is going to kill a lot of people. I know this is answering a question you didn't ask, but teacher morale is absolutely in the toilet right now. Check out online communities like r/teachers on Reddit if you want to see what I mean.
Teachers feel that they are being treated as disposable, they don't trust the admins or the parents to keep them safe, and they are quitting in droves.
We need to reduce the load of stress on teachers, parents, and kids, but without just passing the buck around.
Speaking as a veteran teacher, the answer is very simple: we need to treat this year as a loss. Suspend all high-stakes testing, start getting ready to remediate and reintegrate for the next few years. We can't make progress under these conditions.
We can't even stop the kids from sliding backwards.
We are in survival mode. Let's acknowledge that and start looking for ways to recover in the future rather than setting unrealistic goals for ourselves and our students.
