My wife works for a school system that at one point had the following proclamation handed down:

"We're referring too many black kids to special services. That could be because of racism."

Keep in mind these were free services like speech therapy, help with reading and so on.

So in the spirit of not being racist they decided the teacher's couldn't use their own judgment on who needed services and offered black and other minority students fewer services.

Public school administration is just poor all around. For many their first response is to blame teachers because that's the easiest target. The union is of no help either. Any complaint from a parent, even well known problem parents, is a whole process of emails and meetings and etc with no real resolution. It takes an endless amount of time before it's clear "problem is the parent" and by the time that is decided they're gone and on to the next parent who submitted their 6th absurd complaint this year and everyone starts over wagging fingers at the teacher's.
