Just another stereotype for the parents who know everything. I remember when I was a school pupil there were some parents who would know everything (ok, almost) what was going on in the class even though some information was kind of confidential (IEP, other things). How do they manage to find out about confidential information? Would this come from another parents or a teacher? I doubt the very young pupils are capable of telling everything to their parents or even understanding many things happening in the classroom.
