To the OP - I do not know anything about Devon schools. However, I feel you need to be warned about some of the posters here. I find it incongruous that posters who live in Cornwall should express such strong views about schools in Devon and then completely off track recommend a school in Somerset, which even my scant geography of the area would tell me was not suitable for someone asking about schools around West Devon (and Plymouth?).
Fwiw I would take what these posters say with large pinch of salt. I would say, as an independent school teacher, go and see all the schools around your area and make your own decision. I very much doubt there would be any real considerable differences in them, so you base it on what you like and what you are actually wanting from a school. You also need to understand that those schools mentioned here are all very different kinds of schools which would suit very different pupils. You need to look at that and be clear about the kind of school you are looking at, the kind of DC who go there and what is offered.
Having, like others looked at the web site, it seems to me that ?Kings" is a school similar to the small prep I have selected for my own DS. Now, I suspect this would not suit most MNers. It seems to be a school with a strong moral Christian base. My DW and I selected a school similar for reasons quite separate from what most parents might select upon.
Finally, I am getting quite annoyed, indeed angry at the snippy remarks being made about one school by these particular posters. Maybe they think it is funny. I think they are being b* * * y.... err..... Prejudiced. In the time I have been around and I have seen many comments from these two concerning that school, they have said absolutely nothing to substantiate their views. My feeling as an outsider is that they (or at least one poster) is actually an advertising placard for the school they recommend and nothing else. To do this they6 need to be disrespectful to their opposition. Of course they will fervently deny it. It is just my observation of course.
As a teacher in an independent school I am concerned about those comments. Any one reading may think they are authoritative. As far as I can see they are not. It is not acceptable in my view to make unsubstantiated comments about a school as they do. If it were my school being so bad mouthed without evidence I would be inclined to write to MN moderators. That may sound harsh. It is nothing to do with me, so I will just place this warning here. Be careful how you take advice on this site.
