"there's another about 10 miles down the road that has GCSE results within close touching distance of our grammar."
LaQueen, you do, I am sure, realise that comparing headline results between a grammar and a comprehensive is meaningless? (I know that I then proceeded to do the same
)
A grammar, with its selective entry, would be expected to get much higher results than a comprehensive, because the latter takes in children of all abilities. In particular, in 'comprehensives' in or near grammar counties, the top ability children have been taken OUT of the comprehensives so the gap would be expected to be even larger. This is why the 5 comps - technically secondary moderns - in my county that get comparable / better results than the grammars really do do extremely well.
A much more meaningful comparison would be obtained by going through the DfE tables to compare results for HA / MA / LA children in each school. As I can't face that, I use value added as a shorthand, because it measures, whatever the starting point, the progress that a child makes in the school, and so compensates for the different starting points in grammars and comprehensives / secondary moderns.
[There was someone upthread who said that it was easier to add value to less able children? If I asked you whether you would rather teach top set - who have all made above average progress in primary- to get an A, middle set - who all made expected progress in primary - to get a C, or bottom set - who have all made less progress than expected in primary school - to get E, which would you reckon was the easiest task?? Each gets you equal 'added value' points, as each is 'expected' progress [I may have the exact grades out a little, but you get my point I hope)
