Pubic school cost about 7.5k per child per year,
On a per-pupil basis the total funding to be allocated to schools for 5-16 year olds, in cash terms, in 2024-25 is £7,690, a 49% increase compared to £5,180 allocated per pupil in 2010-11.
After adjusting for inflation, funding per pupil was broadly flat between 2010-11 and 2015-16 at about £7,200 in 2023-24 prices.
It then fell by 3.9% over 2016-17 and 2017-18, but subsequently increased by 1.2% over 2018-19 and 2020-21. Since then, funding has increased by 7.9% (after adjusting for inflation) over the course of the following five years, reaching £7,570 in 2024-25 (in 2023-24 prices).
Broadly speaking, the average cost for private day schools is £4,980 per term, or £14,940 per school year.
so... £3k in tax, for the people that can afforded it and for the ones that can't - back to public school costing us £7.5K makes perfect sense.
