Pernille Ripp just published a parent end of year survey she does with parents of her students every year.
It’s a good idea. She does it online, but it can also be done with pen-and-paper. Of course, even though I think the vast majority of parents are equally committed to the well-being and success of their children, many may not have the time, literacy level, language fluency (of course, it could be translated) or technological ability (in the case of an online survey) to complete such a survey.
However, in situations where those are not obstacles, it seems like a good practice to try.
