There are so many on here that don’t understand (or are disingenuous) about how private schools have priced most middle classes out over the last quarter of a century or so.
Yes, everything has gone up (doh!). We use CPI to measure this. Private school inflation has been running at approximately 2xCPI over the long cycle.
Why is this? It is hard to know. It is neither teacher’s salaries, which have risen sub CPI since 2010 at least, nor is it class sizes, which have increased.
And no, as a PP said, it isn’t profits as they are charities.
It is an arms race led by pushy parents for flashiness and facilities. So, parents want tiny A level classes to be supported (History of Art, for instance), They want theatres staffed by an array of technicians and professional level lighting. They want the school to be open and staffed to look after pupils from 7:30AM to 6PM. They want a large marketing department and many want a large SEN team. There is plenty more I haven’t mentioned that wouldn’t have been the norm 25 years ago.
The above all have some value but parents aren’t generally consulted and a lot of this isn’t about education at all but the enjoyment of a bespoke and privileged experience, often to the detriment of genuine resilience; not a story they tell, obviously.
Several heads of famous private schools admit to this and say the arms race is parent driven. The 20% isn’t nice but it’s nothing compared to the 100% odd in excess of CPI that fees have gone up since I attended school.
