The question is a simple one: 'If you are able to afford Christian schooling, why dump your children into state schools?'
State schools' countless negatives have been previously listed on this Blog. It is a very long list!
Christian schools have their disadvantages, certainly, but if I had my time again and there hadn't been a Christian School available (founded by my wife and myself or not) - I am sure that we would have home educated our children.
Some junior schools are acceptable. The comprehensive where I taught for 28 years, and rated as very good, would certainly NOT have received my children from 11 to 16.
I have seen too many youngsters from Christian homes have their basic beliefs damaged in such a context.
