I'm sorry i dont really understand the problem. She preforms badly at maths and therefore has been put in the lowest set. Are you suggesting that she should be in a higher set, where shes going to be unable to keep up just because she hates being seen as less than average. Thats not how streaming works. Of course shes been put in the set according to her ablities.
As for looking up her timetable, and if not having had to find out at school. Well tuats how many many people found out for many years. As for not being able to ask questions as a pp saud. Huh what? Are you expecting kids to be able to go i dont like which set im in can i change it please.
As for not liking the teacher, im sorry you cant like every one. And they cant like you.
The only thing i would have a bit of a problen with here is that youve not had imput from or to the senco, its importsnt that the school and parents are singing of the same page so to speak, that she gets the support she needs at school and home. That you have an oppunity to express your concerns etc. Which clearly hasnt been the case if youve not spoken to the senco.
As for her self esteem, as ive said just because she hates being seen as less than average, doesnt mean the school can or should just change her set, you AND the school need to work with her on her confidence etc, again a reason the senco should have spoken to you.
I appricate it can be a very hard to hear your child needs additional help, and i really do understand that, but maybe thats part of your daughters self esteem issues that she feels that you want her to be more than average, this i am not gong to send her in, is sayimg to her its not ok to be in learning support. Im sorry but if thats what she needs then it is ok.
