In areas children can enter a prestigious grammar school if they pass the eleven plus exam; there are also a number of isolated fully selective grammar schools and a few dozen partially selective schools. A significant minority of state-funded schools are faith schools, which are attached to religious groups, most often the Church of England or the Roman Catholic Church.
