This table is misleading and I take little notice of it. It ranks schools according to aggregate points and that generally pushes up schools that do a homongorous amount of GCSE. Its based on quantity not quality. Telegraph had a useful one which ranked schools according to A*/B but it seems they have updated it with the new one today which is more misleading. Henrietta Bennett had the best GCSE results but if you look on the BBC table its quite some way down and yet there are some grammar schools which perform nowhere closer to it which are ranked above it.
Quick scan shows two school in my area near the top yet there are nowhere near there. One has children doing 14 GCSE so pushing up aggregate score, another a local indie is very good at getting C grades, a couple of Bs and a sprinkling of As is near the top too and my guess is they also do a massive number of GCSE.
I personally would take more notice of the English Bacc results as they show a much clearer picture of who is at the top and not hiding behind soft subjects. Infact I really like the Eng Bacc, its a much better reflection of how school perform in my area. Its not 100% correct but its much better the useless agg point and 5 A/C which tell very little story about the subjects choices. Some of the worst in our areas is a grammar school coming down from 96% to 27%, a comp from 88% coming down to 13% and another from about 49% to ZERO (and rightly so). The argument by schools is that some arent geared towards more academic subjects but from a parent's point of view that should be reflected in the results for me to have a better informed view. I am loving the new Eng Bacc
