100% this, and all those parents are also now wondering and worrying what will happen to their child next school year, when they're either at or ahead of grade level, but half their class is most of a semester behind. I had been reasonably happy in public elementary school until now, but am seriously considering private schools for next year because I'm convinced this reacclimation process will be much, much smoother with fewer regressions.
