This may be long and I will try to condense to the relevant information.
DS1 is in YR6, DS2 YR5. DS1 has ASD and is statemented.
At October half-term there were some major changes in the school following a dreadful Ofsted inspection. The Yr6 teacher left and a temporary teacher was employed. A lot of assessments were done.
As a result of the assessments, DS1 was moved along with 7 others into Yr5 for Maths and DS2 and 7 of his classmates went into Yr6. I was told DS1 was lacking confidence in maths (had previously been told he was a the more able end but there are issues about him producing work). The temporary teacher had a lot of problems controlling the class, and the Yr5 teacher has boosted DS2 up in maths so I had no real concerns, although found it a little odd. I was more concerned DS2 may be missing out things by leaping a year.
Since the new term in January the Yr6 class now has a permanent teacher. Because of all the upheaval, it was decided the Yr5 teacher would teach Yr6 maths and the majority of the Yr6 class now goes into his class for maths (a few stay in for a targetted TA group) and the majority of Yr5 go into Yr6, apart from the original 8 who were previously going into Yr6, which includes DS2.
DS1 has not been reacting well as DS2 is very quick to grasp maths concepts and apparently is nearly always first to have his hand up when he has completed his work. DS1's TA noticed that as soon as DS2 does that, DS1 stops what he is doing and it all goes terribly wrong from there, refusing help, tearful and angry.
It is has now been decided that DS1 will go in with the Yr5 children to be taught maths by his class teacher. DS1 is also unhappy about this, but is is a very recent change so I don't know whether he will settle down.
I just find the whole thing over-complicated and confusing. My relationship with the school is a bit tense, and I don't find the new Yr6 class teacher to be particularly understanding of DS1's difficulties, as he seems to think DS1 is choosing to behave awkwardly and has threatened to have him permanently taught outside the classroom by a TA if he doesn't stop being rude. (I have spoken to DS1 about this and reiterated he mustn't be rude so I am not excusing it, but he is very stressed and struggles to manage his emotions when he feels people are "getting in his space").
The most obvious solution to me would be for the Yr6 teacher to teach the Yr6 maths and the Yr5 to teach Yr5, and all the children to stay within their actual year groups but perhaps I am missing something? No other subjects are taught out of year groups, it is just maths.
if you have got to the end of this, thank you very much! Any comments or advice would be very welcomed.
