Nothing they do should be secret from parents. NOTHING.
Everyone has horror stories, so I won't bore you with all of mine.
Suffice it it say, that a mid level administration bureaucrat at my my child's school, clearly stated that it was actual school policy to refuse every student's personal preferences, regarding teachers and schedule, simply on the basis that the student stated an individual preference.
Think about that for just a moment...
“Nothing they do should be secret from parents. NOTHING.”
Why not - the parents aren’t paying for it, the government is. It’s none of the parents’ business what get taught.
...and that is how parents are looked at by the schools. Nothing will change. The parents are nothing more than babysitters for the kids, since housing the kids at school is still too expensive.
