In my local authority 48, 23, 25 and 22% respectively, of pupils achieve grade 5+ in English and Maths.
In the selective schools the figures are 95 and 81% respectively.
Fee paying schools chart GCSE achieved rate differently in that they show attainment at % grades level 9 (A*A) and the figures in my LA are 84, 87 and 75 respectively.
Those that choose to pay for their children’s education because they can afford it or make life choices and sacrifices to do so, are not making these decisions with thoughts of how much better it will make their Johnny and Sarah (I’m not lambasting Johnny’s and Sarah’s), than other people’s Johnny and Sarah’s, they are looking at the numbers above and deciding on the numbers.
