very interesting, but does not surprise me ,KH has always been well regarded with respect to CVA, what does surprise me is why it does not have more high achievers/prior attainers to start with, given it's demographics are very similar to areas like Wilmslow, Appleton,Lymm generally very affluent areas with it's fair share of profesionals/business families yet consistanty is much lower in the league tables as compared to Bridgewater high, wilmslow high or Lymm High.(Trafford comps are differant almost 40% in Trafford go either to grammars or Indies given this , I think even the Trafford Comps do very well relatively speaking)
1) problem with the primaries ( I doubt that ,they generally have a very good reputation)
2) high achievers are been disaproportionately been "saphoned off "by the Indies ( King's, Grange,Stockport, Cheadle Hulme and the three manchester schools)? resulting in more then expected number of out of area children from disadvantaged areas , if so ,good on KH.(however I not aware of many disadvantage areas around Knutsford( but as I have eluded to before my goegraphy is crap
)-judging from the house prices-but I do know that lymm High have a very positive attitude from parents from areas like Partington in Trafford applying(-no disrespect to Broadoak's) but I think it's not all altruistic , any parent thats prepared to send their child 5 miles without a direct bus route must be quite aspirational!-but a counter agrument would be that Lymm also has a good number of it's high achiever "saphoned "to Indies and the Alty grammars.especially ABGS who are "super-selected" so they take our best and brightest boys!and AGGS who take some of our brightest girl's due to the close approximity to the school
anyway well done to KH
CVA is the most important measure about any school (difficult to know about the indies as they have no compulsion to declare them in the public domain)"it's all about what you bring to the party" but to fair ,to the selective schools there is "the rule of diminishing returns "at play as determineddaddy has implicitly implied in his earlier post so it's no real suprise most Grammars do badly compared to good comps like KH with respect to CVA.
