The school has a choice - run the traditional offers system, which gives parents 3 weeks to choose and then sees large numbers decline because somewhere else amongst their 5 or 6 choices is their preference. They can't significantly over offer in this scenario because a bulge class absolutely isn't an option due to space constraints, so if they use this approach and only slightly over offer, they will always have to go to WL and bearing in mind that due to location, they are often not top choice for many of the 800 applying, they will have to go far down it.
Or they can do what they have and have certainty of numbers from girls they are happy to give offers to.
From the schools point of view, it seems simple and clear which is best. They have decided to put the school and it's current pupils first, rather than a lot of parents who apply and want 3 weeks to decide and who then mostly decline anyway.
Seems entirely sensible to me.
Most of the objectors to this are not people who desperately wanted a place. They are those who would have declined at some point anyway, but feel annoyed at not being given the 3 weeks to choose to decline.
This is a parents forum. Many people struggle to see this issue from a school perspective and to understand the unique circumstances of City in terms of location making it a possibility for many, but probably not top choice for large numbers of the 800. They also don't realise what being in the Barbican means for space and planning - there is no putting a temporary classroom in the playground here. Many also don't want to see it from a school point of view or to accept that there is always a balancing of school interests against those of prospective parents, and schools must make judgements about where the balance should lie and things like locations and physical space might make that balance different for different schools.
Why shouldn't it be first come, first served for those who have met the required standard? Why shouldn't parents get on and decide beforehand - perfectly possible if they hold sensible rather than daft numbers of offers following applications. Why shouldn't parents accept that like many things, if they want to spend longer choosing, some of the options might have sold out? A different system isn't necessarily wrong - it is simply different and a response to circumstances that schools find themselves in - this all arises because parents want to apply to lots of schools for insurance - but the reality is that each child can only attend one. It is schools that are reachable by huge numbers and successful that then find that perhaps 3/4 of the applicants aren't actually very serious. Yes those other 1/4 are far more than needed, but how to get the offers to the right people before they have gone elsewhere and without overfilling? It's impossible with the current system.
