I went into this thread thinking that I could help out, but it looks like WTP did a great job on the elementary schools and like Shopping613 can probably help out better than I can with the high schools.
I just want to remind anyone who chooses to comment on this thread that they should be very careful not to post any loshon hora (which can be hard to avoid with this type of topic).
While there are certain things that can be muttar when speaking to an individual since there is “toeles” this is a (very!) public setting, so that wouldn’t be relevant.
Since it can be difficult to know what’s l”h or not when dealing with such a topic, my recommendation would be to picture the principal of the school standing right next to you as you type. Imagine that she is your best friend, and think, “Would I type this in front of her?”
