Being a technocrat, if I have a question about school policy, then my instinct is two-pronged:
find the document that explains it: the student handbook (K-12) or bulletin (university)
find the data.
Naturally, not trusting a teenager to even know where his student handbook is located, I went to the web site. This one is terrible. It took me half an hour before I was satisfied I had found it.
Worse, the document reads as though it was written by an Ed.D. and a lawyer. It sought to define terms in legalese like governments do, such as what an infraction is, the severity levels, and the recourse the school administration will take. If the parents typically have a reading level of at least a bachelor’s degree or above, then I think this is fine. If the parents lacked upward mobility because historically this school system failed them, then they probably will struggle to understand these rules.
It makes me wonder if part of the reason the school system has such problems with discipline is due to parents and students not really understanding the expectations because the school is obscuring it from them. The students find out things are wrong after getting caught. Which makes things seem arbitrary.
Of course, parents have to report they understand the rules. How many actually do? I suspect not many teachers do.
They have their own classroom rules and probably only enforce the school ones when made to by the administration. Of course, this means navigating a random set of rules in each class plus another set outside them.
