Yes - they should find something positive to say about your dd.
I know what it's like to have something like this - when ds1 was in year 1, his first parents evening the teacher was really negative about him. The only positive thing she said was that sometimes when he was on the carpet and supposed to be listening to her, he was chatting to his friends. This is positive because it meant he had friends - for the first term or two he really struggled to make friends and was convinced that he didn't need them because he would still see his nursery friends (we didn't really as we didn't live anywhere near them any more).
The teacher also told me that ds needed to learn how to talk in sentences and join in more instead of doing one word answers - at which point I would have choked on my drink if I'd had one and asked the teacher if we were talking about the same child - as he is the most talkative child I know, has an opinion on anything and everything (even if he has never heard of it!) and is keen to share it with everybody. If I frequently ever ask ds to stop talking, I am lucky if the time he is quiet for is seconds rather than nanoseconds. His teachers before and afterwards have all commented on his chattiness, willingness to share, his wide general knowledge - she was the only one that had a problem with him.
She also told me that he didn't concentrate and got distracted easily, and needed to learn how to concentrate for longer. So I said I was surprised as he will happily sit and concentrate on things at home for hours at a time, on all sorts of different things. The only time he gets distracted easily is when he is isn't being interested and engaged in what he is supposed to be doing (and he loves finding out new things and learning stuff, so that usually applies to things like being bored when tidying his bedroom!), or being told things over and over again that he already knows, so that if she were to teach him in an interesting way then she shouldn't be having a problem with him getting distracted.
Needless to say that didn't go down very well. And I ended up having a problem with the teacher all year - found her very difficult to communicate with. Lots of the other parents found her a problem too.
Think part of the problem was he missed the first 10 days of the year due to chicken pox and suffered from missing the transition period into his new class, he never really settled until he was in the summer term. In his Y2 class however and now in his Y3 class he settled in, had a great relationship with the teachers and has bounded ahead, loves gonig into school. It was just one mean old teacher that screwed up a year for him (and I really think he went backwards in her class).
I would have cried when I came out if it wasn't for the fact that I bumped into his reception teacher by chance when I came out and she was all 'ooh it's lovely to see ds coming on so well' - but I would never have known it if I hadn't spoken to her.
and breathe....
sorry, that turned into a bit of a vent.
But it is because it is a big deal when teacher's concentrate on the negative things about your young child, particularly when you know your child and know that actually if the child was interested by the teaching better, they probably wouldn't need to be vacant in order to do what they wanted to do as they would want to do what everyone was doing!
