I am a Christian, and it is important to me that the school I send my children to is sympathetic to my faith.
I will not be placing my most local school first in my list, I will place the primary school in the village 3 miles away as number 1, and then a school in another village about 3 miles away as number 2. My local primary will be bottom of my list - it is not where I want to send my daughter.
I know that for some areas, especially in London, it is more tricky, but for my first choice school, our faith will put us in position 7 out of 8. We live outside catchment, but worship in a CofE stream church.
I don't personally think that given our location, this will make a huge difference, but it will make a small one, because it will put us above the other children in our estate of the same age, so gives us an advantage of about 2 places.
I am hoping that with a PAN of 60, and some of this year's intake being as far as 15 miles from the school, that in 2 years' time when I need a place, My DD will be within that 60.
I think the question you have to ask is why so many people want places in a faith school? Why are they performing so well?
In my school, it isn't as easy as wealth and class. It is rated outstanding by ofsted, yet ofsted recognises that there are a large number of travelling children that attend the school, and there is a usual mix of well-off middle classes and less-well-off families (such as myself).
I do feel for people who strongly choose to practice no faith, and on principle feel discriminated against. But what you are suggesting, is that I should not be able to access a school on the basis of my faith, when that school is specifically attributed to that faith. That strikes me as a bit of sour grapes. But, I can see that it would put you between a rock and a hard place. Those with less conviction would attend a service once a month for a year, and get a recommendation from the priest.
I don't agree with that myself, but as I have attended church fully and served as a committed member for the last 12 years, and my children are only 2.8 and 12 months, I don't have any issues with getting a letter of recommendation from my pastor, so I haven't got the dilemma to consider.
