Thanks for your responses. I have a meeting with the school next week, so I will get a chance to hear their opinions. If it sounds like they think she would benefit from moving back down, I think I will support that. I think I had the idea she would make a bit more progress over the summer than she did, and she seems further behind rather than closing the gap. And no, I don't think it's fair for her to be struggling without any real reason.

I was more concerned about the emotional impact of a repeat last year, but I think if she really is struggling, she will be relieved to move down and not be the youngest and at the bottom of the class.
