‘Question! Are private and religious schools flourishing in the UK?’
Yes, a third of all UK state schools are now faith schools. The vast majority are CofE, then Catholic followed by a few Jewish and muslim ones. The govt are duty bound to fund religious schools in the UK providing there is sufficient local need for them. They also tend to perform better than non-faith schools, though in Britain, all states schools must include religion to some degree, usually religious education classes and hymns at assembly.
Private (where the parent pays fees for their child to attend) schools are also popular.
I wonder if they also include the madrassas inside mosques. Pretty soon Indians and Chinese would be the only ones in Britain that graduate from non religious schools.
BTW I did most part of my schooling from a Christian convent in spite of being a Hindu. It would be unimaginable for Christians or Muslims to study at a religious school other then that of their own religion.
