I wonder if this is something to do wit the new admissions code recently published?
I think it says popuar schools can now expand if they want ......STR, Chosen Hill, KLB, HSFG, Pates, Balcarras, Cotswold, CHipping Camden, Dean Magna - all excellent. Would it be good if they all increased by, say, 2 groups per year each? As long as they could mnage the extra numbers (a bif IF) with a few extra classrooms, maybe, wouldn't everyone benefit?
Don't forget SHS - also had an excellent OFSTED last year. Of course, Acadamies no longer have OFSTED reports made public.
Yes, the new admissions code (only proposed at the moment, as not yet agreed by parliament) does allow schools to increase, which can be seen as a good thing - however, it also means that other schools will have a smaller intake, thus lower income and decreased facilities / courses.
So what, if it's a poor to avereage school? Well, if you live near to it and have a low income (even the middle class can find themselves unemployed), you may well not be able to afford the bus fare (or fuel for your Range Rover) to the 'increased sized better school'. You won't get free transport as it's not your nearest school.
If Grammars increase in size (and I seem to remember that they are not allowed to), then they would have to have a lower pass mark to increase the intake, thus the average ability of a child at the school will be lower and the range of abilities in the classroom becomes wider, so the teaching becomes less focused. Remember, there's only so many children bright enough for grammars in the county, and increasing the number of grammar places won't make children brighter!
