I spend so long tying myself in knots trying to avoid being a pushy parent that it's a miracle I ever say anything at all.
I also think that madwoman is spot on about addressing the lack of confidence issues (I think that this is perhaps a more useful phrase than 'self esteem', certainly I prefer it for DD).
I had a meeting with the teacher today, mostly about olayground issues, and she is currently finding strategies to encourage DD to speak up. And I think this might be helpful across the board; because if she speaks up in lessons they will know what she can do and, perhaps more importantly, she will get praised for it. Then she will feel more confident, etc etc. So if anyone has any ideas about how to do this outside the classroom, that would be handy. (And, incidentally, they have realised that differentiation in the classroom won't work, so she will be going up to Yr1 for guided reading, which is a bonus
).
I'm intrigued that Peter Congdon suggested going to the press - that suggests her report puts her in a very high percentile indeed. I don't think it would help with the current school much, would probably just make them more defensive. More useful, I would have thought, if you want to try and get a bursary for her either now or later on.
For us, school have been concerned not to isolate DD from the group (something she's quite inclined to do for herself by wandering off to sit in the corner with a book), and so we don't tend to make much comment on her reading, but I think that not acknowledging what she can do has actually undermined her confidence more.
MWITA - I'm with susan, if you'd wanted an assessment, you'd have had to fight tooth and nail.
