Here is a post from 2012 on the topic of communicating with parents early on in the year before it’s too late:
I was communicating with a teacher about getting the parents of kids who act out in class involved early, actually right away, at the beginning of the year.
I have not called parents early on. When I have, later in the year, quite a few have answered that there is nothing they can do, that it is my job to make them do their work, etc.
It is a disaster when parents throw their own solemn responsibilities onto teachers. You must absolutely refuse this comment. That their child is a jerk in class is to no small degree their responsibility, although you cannot say that to them, of course.
