Not keen on your voucher system blu. I chose my son\s faith school because its good with SN (and my 2nd choice school was also a faith school chosen because it was good with SN). I suppose a voucher system would be good if you were choosing a faith school because of the religion aspect, but for us personally what they teach religion wise is totally irrelevent. A voucher system would have limited my ability to apply to those 2 schools and we would now be home educating.
We applied to 4 shools, 2 faith, 2 state. One state school was unsuoitable, we were rejected by the other and were offered places in the 2 faith schools. No religious discrimination going on, and the church funds whatever it funds of my son's education. I can't see the problem.
