If a school district did not come up with an appropriate plan for this fall then the parents in that district need to voice their concern.
I don't believe you can look at last spring with any sort of criticism. In my district, they announced that school was "postponed" for an additional week after spring break. Really no need to adjust anything. A week later, they delayed it 30 days, basically until mid-April, at that point you had to begin to come up with alternative ways. There wasn't a whole lot of time to come up with the necessary technological alternatives to get that info out there.
But as I wrote above, from late April to August, there has been plenty of time to come up with ways to get the teachers in front of the kids, virtually, in person, or a combination of both.
In my experience over the last 6 months, as we've dealt with Covid related issues in the school setting, most of the parents who pay attention to the communications from the school district have fewer issues with the plan. Sadly there are far too many that do not keep up with the communications, then want special treatment because "they didn't know" what they were supposed to do. Glad I am just a teacher and not an administrator.
