A quarter of the schools were found to be faith based. While these schools can technically be inspected by Ofsted, at least 80 smaller ‘teaching groups’ have been set up, often in warehouses or above shops, and are outside its control. Texts seized from some Islamic faith schools have included instructions on how to beat a wife, instructions that she cannot ‘refuse sexual intercourse without sound reason’, and that celibacy is unlawful. Ofsted suggests that religious extremists are exploiting lax home-education laws.
