Mumtryingherbest: "How do the demographics compare to those who are practising the faith in the local area? If the majority of families attending church on a weekly basis are predominantly white middle class families and the intake criteria requires them to do just this then of course the demographics will show this"
Yes, of course it will, and that's why a school that selects on those criteria will have more of that demographic. And if others who wouldn't normally go to church decide they want to go to a school with that social make-up, and start attending church, then the admissions become even more skewed, and if it is oversubscribed (as many are) then the less organised families who don't meet the criteria are pushed out. That is exactly the problem.
"I can't see any mention of the academic performance of the various schools (if you have a link I would very much appreciate it)."
The FAC heat map covers all faith primaries in the country that have faith-based selection criteria, and compares their socio-economic make-up with neighbouring schools.
Performance data is available elsewhere online for individual schools if you want it, but isn't included in the FAC study because it isn't relevant.
"I can assure you that the demographics of those attending the local non ranked schools differ very differently from those of the academically selective schools."
I think here you're talking about selective grammar schools, rather than faith schools, yes? As I said before, that's a separate debate.
"The performance of the school can have a significant impact on the demographics."
As I said before, the (socio-economic) demographics can have a significant impact on the performance, and as soon as the performance starts to look slightly better than other local schools, that skews the demographics further. It's self-reinforcing.
"How have these demographics changed at these schools over the last 5 to 10 years, a period which has seen a marked increase in pressure on school places? The outcome of which will see people going through the motions to tick boxes on a form in order to get their DC into a good performing local school. This is not caused by the faith criteria, it is caused by the pressure on school places."
Yes, the pressure on school places (which is increasing, and will continue to increase as there is a national drive to reduce surpluses) is bringing the problem to a head. If people have a lot of choice they don't mind so much that they can't get into one or two of their local schools quite so much as if they have no choice at all and can see that others do have choice at their expense.
"How does this research map onto the rise in house prices closest to those schools?"
As I said, it is comparing schools with those that are in the same area.
"I would imagine many families are researching the admissions criteria and ticking the boxes to get their children into their preferred school. This has nothing to do with faith but everything to do with the parents doing whatever it takes to get their child into the school they view most favourably"
Yes, which is why it is an arbitrary system for admissions which skews the demographics.
"not so sure I understand how the faith criteria results in a better academic performance. perhaps you can enlighten me on how the faith criteria improves the academic performance of a school? Are children of faith naturally brighter?"
Of course not. You misinterpreted me. I meant that the academic performance tends to be a product of the socio-economic selection, not the faith selection.
"and schemes which encourage the most able teachers into schools that need extra support. such as prioritising children of staff over and above local children in way of a recruitment incentive"
No, that achieves the opposite - it encourages the most able teachers into schools that are already doing well, rather than the ones that need extra support.
