I have boys at both NKS and The Harvey. NKS has been though some changes over more recent years with the new HT being appointed. I have made no secret of my dissatisfaction of her at times, however as things have settled down my opinion has changed.
DS1 & DS2 both went to NKS and did very well, we had little cause for complaint and with regards to pastoral care can only comment on one issue. DS1 started year 7 and went from 'top dog' to 'average Joe' and found the transition quite hard. He came home on a couple of occasions 'sick' but in reality was just upset. The school were brilliant and supported him through that time. DS1 left deciding not to take the Uni route, which wasn't what the school wanted, to take up an apprenticeship with a firm of Accountants. DS2 has recently attended Cambridge for an Interview to study English. He wasn't successful, we pretty much knew he wouldn't get in, it's sooooo competitive but he will be going to Uni in September. Anyway the point here is they did very well. I would recommend the school. They have really good sport opportunities if you want them. DS1 was Team Captain of the Football team and took part in loads of other sports, but DS2 was hopeless and was regularly told he wasn't as good as DS1. Don't take that the wrong way, it was said in jest and accepted with good humor. After all DS2 is outstanding at English Lit but DS1 never picked up a book unless it was to move it LOL
DS3 is now at the Harvey having failed the Kent Test and we failed at appeal for NKS. Harvey don't do their own test for admission to year 7, it may be you saw they test for casual admissions but all the GS's now do this. Harvey are always very heavily under subscribed, last year they had over half their PAN unfilled on allocations day. DS3 is very happy, so much so that there are now spaces at NKS in his year group but he doesn't want to go there. I think not having to follow his brothers has actually been a good thing as there are less expectations on him. The Harvey have had very good exam results, especially when you consider they do take quite a number of boys who failed the KT and got in on appeal so considered less able. This school is also subject to a bit of snobbery in my view. Parents from that area send their DS's to Canterbury or Ashford (also Dover who do their own entrance exam) and I have to say I have no idea why when this school is actually very good. It may be still stigma from a previous HT who left the school in a bit of a mess, but there has been a different HT for quite some time and he is now retiring with the post being filled by the Deputy I think. Not had any problems at this school either and would recommend quite happily.
The only thing I would add is that you get a feel for school's and I know some don't like both of the above for a number of reasons. Check out the league tables if you want to know how they 'perform' exam results wise too.
