Best co-ed boarding school for DD?

I don't know a Rugby particularly well but I suspect many could come on here and makes comments like schoolchoice. It's all about finding a school that suits you and your DD. If she likes water sports fairly obviously, although I'm always amazed at those who don't, look into the provision for her interest and as importantly how frequently she can do it and to what level. At my DS's school rather unusually there is no major sport each term So he is able to peruse his slightly niche sport at least 3 afternoons during "games" lessons instead of standing miserable on a rugby/football/cricket pitch three afternoons a week and doing it as an extra curricular activity. This is not always the case at all schools. Ditto if she wants to do a particular A level, a mother last year on MN criticised the Pre U choices offered by my DS's school but the choices are clearly listed in their website for all to view why let your DS spend two years at the school and then start moaning about no computer science/media studies Pre U. Also as you're abroad it's worth finding out if your DD can leave a day early at the end of term or arrive a day late most schools are flexible but some won't be this could annoy some I suspect! Finally be careful about the term "full boarding" my definition; sleeping at school 7 days a week is not everyones, remember these schools want you're money bar a few very big names they are struggling to fill every vacancy, they'll almost say anything if they think it's what you want to hear, if necessary get the head/house mistress in a head lock to squeeze the actual number of full boarders out of them, ask more than one person see how much variation you get. Do you research carefully, don't assume it will be there because you're stumping up 34K a year, as I always say if it matters ask.

Rugby is considered by many to be the best coed boarding school for girls.

For a variety of reasons the two you have mentioned would not be on my list,not least because Idont think they are either full boarding schools,and as you are abroad you need to know that a good number of children are going to be around at the weekend,try looking at places like Rugby,Oundle,both good boarding schools,decent/excellent academics and really good sport,others could be Uppingham,flavour of the month-Oakham,theres a few to be going on with

I was about to say King's too. Good school - academic enough to challenge the bright pupils but lots going on in extra-curricular terms too.

Assuming you not looking for entry for this September I would consider Kings Canterbury, the majority full board which is important if your abroad, Canterbury is a very nice city, it's got a good solid academic reputation and it's very close to the sea so good for those who like water sports. We know lots who are or have been there, all different types clever sporty musical arty quirky all bar one were very happy the very bright ones did/are doing very well.
