Nope. Parents being pushy has no effect, as demonstrated by the numbers of pushy parents in the state sector already who can do bugger all about anything. A couple of extra families won’t change that.
Also, the belief that the really rich ones that can afford boarding are just going to accept the local comp is silly. There are plenty of overseas boarding schools available and if you are going to pay extra it may as well be for flights and a nice climate.
For everyone else, there’s the inevitable fight to be closest in catchment. Or tutors* and HE if you don’t manage it.
*Tutors being a fabulous way for schools to look like they are improving when they are not. Our catchment comp has had its results supported by the army of external tutors for years. Only now the wheels are falling off as good results for the wealthier families can no longer mask the poor teaching for the remainder.
BUT seriously guys - it’s happening and won’t change without serious legal action. If your kid is about to start like mine, you should have factored VAT into your fee expectations. If you started before and you’re short on cash, then you can either move the kid or take out the loan/extra mortgage to see them through to the next transition point.
If you plan to do the former - apply now for the school place as there’s often a lot of movement over summer.
