Subjects In England and Wales the subjects taught in schools are laid down by the NATIONAL CURRICULUM, which was introduced in 1988 and sets out in detail the subjects that children should study and the levels of achievement they should reach by the ages  of 7,11,14,and 16, when they are tested. The National Curriculum does not apply in Scotland, where each school decides what subjects it will teach. In the US the subjects taught are decided hy national and local governments. Whereas British schools usually have prayers and religious instructions, American schools are not allowed to include prayers or to teach particular religious beliefs.
