Although they will already have some settled friendship groups by then, I'm sure she'll be able to settle in well with girls similar to herself. I personally found that being quiet/introverted did not win you many friends amongst the more outgoing gregarious girls - then again, I started in Year 10 as a boarder from a different cultural background, so my experience may not be directly relevant to your daughter.
Toughasoldboots, I'm sorry you had that experience. We did have some bullying in our year (specifically of a girl whose parents didn't want the school to disclose to us that she had CP and possibly an additional/secondary behavioural disorder) and I can't say that I saw much action to curb it (although there may very well have been - the school always prided itself on its discretion when it came to their students). However, I suspect that particular girl's experience would have been different had her parents not been so averse to her peers knowing. I find that people (especially teens) tend to steer clear of others whose behaviour they don't understand/find odd or intrusive when, in hindsight, there was a perfectly reasonable explanation for it.
Yet, I would rate the school highly on pastoral care. They certainly went above and beyond the call of duty when I had some family issues which unfortunately ended with me leaving the school. I would go back on occasion to spend the odd weekend there and could call on my former teachers when I wanted their advice on work in my new school. I have no doubt that she will definitely be nurtured and encouraged to achieve her best - academically and otherwise. I have lovely memories of my time there, still remember my teachers with fondness and respect, and retain strong friendships till today.
You will probably find someone with an issue like that in every school though, I just wasn't prepared to keep fighting them. I really didn't feel that it was an endemic problem , I think it was more down to a particularly clever and devious girl who had very forceful parents.
The school was lovely in many other ways, have you had a visit yet?
One of my dd's went there and all three dcs did for nursery ( which was excellent). I moved her because of a bullying issue which was not acknowledged. let one resolved. It can be a bit of a closed shop rather than favouring open discussions.
I think that the character that we were dealing with was particularly devious and I do feel that pastoral care is pretty good generally.
Beautiful wooded grounds, not known for being academic but that's not a bad thing.
I went there for a few years and would recommend it if your preference is for a pastoral, as opposed to an intensely academic, approach (although, to be fair to them, I (along with a number of my friends) came out with top grades nevertheless). Will she be a day student or a boarder?
