Yes, I did sign the initial RISC petition too. But I saw those arguments as separate from a promotion of free schools - the purist BHA argument is that no new religious schools should be set up, including religious free schools too, and I could see the logic of that in terms of concerns about social and ethnic segregation because I have direct experience of that.
On the other hand, in terms of management of schools, I believe the LA maintained model works in terms of oversight and accountability, whereas the free school system has often led to fragmentation, undermining existing schools, and in some cases to financial mismanagement. I did support Turing House initially, mainly before I knew that the council had planned strategically for the rise in pupil numbers AND sixth forms in the form of the school on the Richmond College site.
My concerns about St Richard Reynolds were that (a) LA-allocated capital funding might be paying for many pupils from other boroughs, and as funds are tight this might impact on the capital allocation of our primary schools, and (b) may adversely impact our existing schools in terms of creaming off pupils.
However, the evidence shows that (a) very few out of borough pupils are accepted at StRR - it is instead providing places for pupils who would otherwise themselves have gone out of borough; (b) there was no impact on admission numbers at non-denominational schools; and (c) it has similar FSM proportion to other non-denominational schools (higher than Teddington or Waldegrave). I also believe it has been managed effectively.
Meanwhile Turing House has a much higher impact on surrounding schools in terms of leaving them with surplus places which makes it harder for them to manage running costs. But because it receives capital funding from central government, the argument on LA allocation of resources does not apply, so there is no reason why it should exclude children from other boroughs.
My question about RISC is this: is it still active, or was it formed primarily a partnership between Turing House supporters and the BHA in relation to the establishment of StRR on Clifden Road? I've noticed that a couple of church primary schools have amended their criteria and now provide open places where they did not before, but this hasn't been reported in any email bulletin or news round-up on the RISC website. So it does seem to have faded out of view in terms of the Richmond scene, whereas the main promoter of that campaign, Jeremy Rodell, has moved onto the Fair Admissions Campaign and other BHA activities.
