Let's just say that parents who had kids with the conditions mentioned received very little sympathy from some of the teachers, with them taking a "parents aren't going to tell me how to run my class" attitude, despite the parents having legitimate things they needed to get across with the teacher that would actually help their children
And indeed, I vividly remember an exchange where one teacher was barking in a parents face that their child was just badly behaved and a "lost cause", when really he just had autism and, with a bit of help, he ended up doing much better the following year with a more sympathetic teacher who was actually willing to listen to the parents and try to help the lad out. So the term "behavioural deficiencies" took me back somewhat and reminded me of that unsympathetic tit. All of us who knew the kid understood that he wasn't actually a bad lad, so how that blinkered fool couldn't see it is beyond me. And amazingly, he didn't even get reprimanded for that either, and I'm only in my 30's so it's not like it was the "bad old days" either. He was not surprisingly a pro caner, and he more than once seemed wistful about it
Sorry, but you reminded me of him with the things you were saying
