The Education (National Curriculum) (Exceptions) (Wales) Regulations 1990
Section 10(3) of the Education Reform Act 1988 imposes on local education authorities, governing bodies and head teachers of schools the duty to teach the subjects comprising the National Curriculum for a reasonable time during each of the key stages defined in the Act. This duty is replaced by the provisions of the attainment targets and programmes of study in a subject in the National Curriculum when these come into force by order of the Secretary of State. In respect of Welsh, the attainment targets and programmes of study come into force over a period of time by virtue of the provisions of the Education (National Curriculum) (Attainment Targets and Programmes of Study in Welsh) Order 1990. (S.I. 1990/1082).
