To give you an example of my local schools ( yes I looked it up )
The only thing that matters around here is which catchment area you fall in. ( when you have to move mid term)
In 2006 The local average of children getting 5 or more GCSEs at C or above:
Local average was 38.7%
National Average was 45.6%
The local secular school 11%
Firstly data from nearly 10 years ago?!?
Also why no comparison with any other local school. But more importantly, so what - so you've got a rubbish non faith school locally and perhaps a better faith one. So what - that tells you nothing about the broader picture as we can simply trade very specific examples.
So the secondary school my kids go to (mixed non faith) is about 200 yards from another secondary school (mixed, faith) - they are basically tapping into exactly the same local demographics.
My kids school - A*-C GCSEs - 86% (most recent data, not from 2006) and OFSTED outstanding in every area.
Nearby faith school - A*-C GCSEs - 50% (most recent data, not from 2006) and OFSTED - Inadequate in all but one area, requires improvement in the other.
And guess what, this autumn 1196 people applied for the 180 places at my school, just 239 applied to the faith school.
But all this proves is my local faith school is really good (and popular) and the neighbouring faith school is really poor and really unpopular. It tells us no more about the bigger picture than your very limited and outdated anecdote.
I've not seen any reports of parents complaining that they don't want their child to go to a faith school.
But I've seen plenty that don't want their kids to go to the local secular one.
Actually there are loads of reports about desperate parents doing everything they can to get into non faith schools, including breaking and bending the rules by pretending to live in places they don't etc.
But the proof really is in the pudding - forget sensational newspaper articles and look at the real evidence, which is of course the schools parents chose to apply to. Did you not read my post - in my city there are, on average, 4.45 application per place at the non faith schools, and just 1.98 applications per place at the faith schools.
And in the county as whole the top ten most popular primary schools are all non faith, and the top ten most popular secondary schools are all non faith.
And this seems to be similar across the country (as even the Telegraph article demonstrates, despite their spin, with faith schools punching well below their weight in popularity stakes) - I remember a recent article about the most popular schools in London which needed two tables, one for faith schools and one for non faith - why? Because not a single faith school would have made in into the overall top ten most popular.
