No, not all Catholic schools as I have found out!
In all our borough all Catholic school except the 2 outstanding ones have changed to accept all looked after/adopted children as priority as per the new admissions requirement. As another poster put it 'not very Christian of them'
Unless they are baptised they slip down to number 6 on the admissions so in the case of these schools will never get in unless it is a low birth rate year or you appeal.
I posted a thread about it on primary education as I cannot get my little man baptised in time as the courts are on a go slow but I can get something called an intention to baptise to support our application. I was not planning to get the little one christened even though I am Catholic as I am very very lapsed but needs must!
Finding God may be too late now as well as it is often a 2 year involvement within the church that is required to fill the criteria. (I am hoping going to church every Sunday and Saint's Day for the first 16 yrs of my life counts as well as having a Nun in the family!!)
I have accepted that he will probably not get in which is a shame as he goes to the pre-school and has started making friends and I was really not impressed with the pre-school attached to the local state school who were not helpful in any shape or form over getting a place as I had not put his name down years ago!!! Bit hard when adopting!
I found out all the info by going to my local council website and then looking at the admissions information page which states each schools admissions policy and additional requirements.
Good luck
