National Curriculum for England
The National Curriculum for England was first introduced by the Education Reform Act 1988. At the time of its introduction the legislation applied to both England and Wales. However, education later became a devolved matter for the Welsh government. The National Curriculum is a set of subjects and standards used by primary and secondary schools so children learn the same things. It covers what subjects are taught and the standards children should reach in each subject.
The current statutory National Curriculum dates from 2014 at which point it was introduced to most year groups across primary and secondary education. Some elements were introduced in September 2015. The National Curriculum sets out the content matter which must be taught in a number of subjects in "local authority–maintained schools".
