My ds is Yr 7 independent school.
He was scoring 80% + in internal assessments at the end of Yr 6 and 78% in a PIM assessment also at the end of Yr 6.
Last term, about 5 weeks into the term, they did Level 1 CE assessments for fractions and algebra which I'm now being told he scored 36% and a Level 2 CE assessment on fractions which he scored just 6%. They haven't done any other assessments since.
He also failed a pre test for a senior school on the Maths paper.
I have repeatedly requested meetings with his maths teacher as ds was saying she had upped the pace drastically and kept refusing to explain anything. She fobbed me off, didn't have time to meet me and blamed it on ds being late into maths once a week due to a music lesson but always maintained that she wasn't able to provide ds with a short bullet point type thing so that he didn't miss any explanations. She also developed a huge fascination with the few times ds forgot his maths exercise book which apparently impeeds progress (we just used to get told to work on squared paper!)
Anyhow, we were told that she was going on maternity leave and ds was looking forward to working with a different teacher as she seemed to be destroying his previous confidence and what he did or didn't know.
Today, I've received an email from the head of maths who was absent for the last two weeks of term that the whole department have decided that as of tomorrow ds has been moved down to what they call 'set 2' which is basically the bottom set along with something about allowing ds to consolidate the basics.
I've arranged a meeting with the head of maths as ds is very upset by this, he worked his way out of this 'set 2' and doesn't want to go back there and is certain that it was a topic specific issue rather than a whole maths as a subject problem. I'm also concerned that this move will then mean that they leave him in this set for the whole of CE as they would be covering the CE topics in a different order.
So, how do I put it across so that they leave ds in the set he is in currently rather than move him on the basis of a specific assessment? I'm not being funny, the pace in the other set is the complete opposite extreme and is everybody who really struggles and we've had no warning of this move at all.
