What is PAN?
Can it change in number?
Published admission number. It's the number the school is permitted to admit. It can change athough in the past GSs couldn't increase it by law, and others could do so only after lengthy consultation and usually faced bitter opposition from neighbouring schools who didn't want to see their own funding threatened. Much easier for schools to increase their PAN this year, as the Warks GS have done.
How do individual heads of the GS decide how many offers are made over PAN each year?
No idea. Experience probably.
Is the real idea of offers over PAN because schools want the cleverer children (i.e. those definitely reaching the pass mark) as opposed to the borderline cases (those on the waiting lists)?
No, the idea is to try and get as close to PAN as possible after initial acceptances. If they didn't over offer they'd have to try and fill more places from the waiting list which I imagine is a much more uncertain process (and the top of the waiting would be the same children that they're over-offering to, so in that respect it makes no difference). The head is looking to fill every single place, because funding is per child. An empty seat is money lost to the school.
Is the 'ideal' scenario: a zero offer over PAN - so those on the waiting list can get a GS place or is it better to have a larger offer over PAN?
It depends who you ask. Zero over-offers is much better for the amateur statistician, it makes the maths so much more reliable. I'll repeat, the waiting list is in the same priority order as initial offers, so whichever approach you adopt it's the same children.
Can you have more take up offers over than PAN?
Yes, but you can't make a habit of it.
Is the pass mark set after working out offers over PAN or is it the other way round?
It would have to be after, wouldn't it? Because if you set the mark first you wouldn't make any offers over PAN.
What are the recent offer numbers over PAN for the KEGS?
Can there really be as much as a 25% rejection of a KEGS (offers over PAN) in favour of an Indie etc?
Not impossible. All/most of the prep school entries will also be entering for some or all of KES, Solihull, Warwick, KH8, etc., etc., and CH will be the fall back option for many of them rather than the other way round as it is for us plebs.
