Perhaps you can enlighten us as to your expertise in education funding?
I posted the table from the National funding formula. The government also states that per pupil funding is on average £7640 per year. You are claiming that your grammar school, which are generally funded at a lower rate than other schools due to lack of deprivation, is being funded at double the national average. That's my expertise....
For example we have had funding for, amongst other things - asbestos removal across the site, new windows, new LED lighting and interactive boards to replace the projectors, all of these were capital grants direct from the DoE, which amount to millions which have to be applied for
Astonishing that your school has managed to get so many millions in capital funding this year when RAAC schools have been told they won't get theirs.
However, as you said, that funding is applied for from the DfE. It is not given to you by the LA as per pupil funding.
If you calculated the ENTIRE running cost of a state school, divided it by the pupils, you would get closer to the lower end (ie £20K) of private school fees.
Don't be daft.
