That is the real elephant in the room. The huge disparity in state education.
I reckoned I could have got a job with the Good Schools Guide by the time DD went to secondary as I had looked at so many schools. At least 8 for primary and over 20 for secondary. Mix of state and private.
Even going via Ofsted it's not simple... I saw Needs Improvement primaries that I really liked and Outstanding ones that didn't even make the short list.
Our local secondary was one that we would have either moved house or gone private to avoid and there are far worse schools out there than that.
A lot of people probably don't even know just how different the same 'free' education can be.
State schools with 4 languages, 7 different arts courses, extra stretch classes for the brightest, huge amounts of extra curricular and loads of visits from experts and professors in every subject immaginable.
And then state schools with nothing more than Art, no music, no drama, one MFL, combined science for all. Next to no extra curricular and nobody seems to care if the results are rubbish.
I don't blame you at all for making the choice you have - I am sure you would prefer to have a great state school round the corner and not be having to find the fees (and be attacked for not being lucky enough to leave on the doorstep of a top comprehensive).
