Well, the meeting got the right result -DS is being moved out of the nuture group in a week's time (not next week because of the CAT tests). If I had been less tough about it I would have had a mauling - I have really taken a dislike to the Head of Yr and I do think he tried to bully me.
First of all he admitted to mishandling the way DS was put in the group and the lack of communication on the matter. No apology though.
Then he went on about how he hadn't seen the SENCO from DS's junior school for 2 yrs (so what?) and he told me how thick DS's file was compared to everybody else's. Again so what? If he hadn't read it, which he clearly hadn't, it isn't much use really is it? He went on to talk about why DS was in the nuture group (as I thought it was to do with a one-off incidence 15 months ago). He told me how they treat the nuture group -basically they keep them out of the mainstream, restrict the number of room changes and teachers they have, they are a mixed ability group so they aren't put under any academic pressure and everybody is apparently very understanding of their difference.
He then said if we moved DS he would be in a class of 26 (how is that different from junior?), it will be noisy(clearly the man has never set foot in a junior school) and he will have to work faster and have more homework (better than being held back and stopped from making any progress). He will have 14 teachers instead of 2 (twat - DS has about 7 or 8 teachers but nice try at emotional blackmail) and he will have change rooms a bit more often which is the only thing that bothers me, but DS knows his way round the school and all the names of the blocks and so long as he tags along with the class, hopefully he will be fine. Oh and the teachers will be less tolerant of his differences. 
Of course, DS would still have to make the change at some point in the year as the nuture group is for a year max and they move them out sooner anyway. In the meantime, they are not helping them with room changing and the volume of work so other than separating him from all the people he knows and holding him back academically, I am not sure what it is supposed to achieve. It is an ill conceived idea.
I just noted it all down and then he just said, so what do you want to do? Tell us now and we will arrange it. No need to hang about, just tell us now. The man is a bully, so I said I would speak to DH but I knew what his response would be and that it was same as mine - he needs to be moved. However, despite him repeatedly saying just tell us now I refused to make it official. He isn't going to force me into making a snap decision and besides he needed to know he wasn't dealing with a pushover. (twat)
So in the end I emailed his tutor who is thankfully very nice and I didn't just say yes or no, I listed out our point of view and the reasons why we thought the nuture group was wrong for DS so he is moving on 26th Sept. I just hope the Hof Yr doesn't sabotage it. I wouldn't put it passed him. Twat. (Have I mentioned that before?)
Another MNer is having trouble with him too. I got a PM in response to a thread I did about Successmaker the computer programme they use and it just so happened that her DS is in the same class as mine. What a coincidence! Anyway, she is not find the twat man very helpful either nor does she like his manner and is having a meeting with him too. Hope she give him hell.
