What is the national curriculum, and who has to follow it?
A statutory framework setting out the subjects and content that must be taught — and the crucial point is that a large proportion of English schools are not required to follow it, which surprises most parents.
Who must follow it. Local authority maintained schools in England. They must teach the national curriculum subjects and the programmes of study for each key stage.
Who does not have to:
Academies and free schools, which are funded by central government under a funding agreement rather than by the local authority. They must provide a broad and balanced curriculum including English, maths, science and religious education, but they are not bound by the national curriculum programmes of study.
Independent (private) schools, which must meet the independent school standards, including a broad curriculum, but set their own content entirely.
Home educators, who need follow no curriculum at all.
Since the majority of English secondary schools are academies, the national curriculum is not, in practice, national.
What all state-funded schools must do regardless: teach English, maths, science and RE; provide relationships and sex education and health education in line with statutory guidance; enter pupils for national assessments; and follow the same qualification specifications at GCSE and A level — which is the real constraint, because exam specifications shape teaching far more than curriculum documents do at that stage.
The key stages: Key Stage 1 (ages 5–7), Key Stage 2 (7–11), Key Stage 3 (11–14) and Key Stage 4 (14–16), with statutory assessment points.
Religious education is compulsory in state schools, and parents have a right to withdraw their child from it and from parts of sex education. Maintained schools without a religious character follow a locally agreed syllabus.
Collective worship is a legal requirement in England and Wales, widely not complied with, and subject to a right of withdrawal.
The devolved nations differ entirely. Scotland uses Curriculum for Excellence; Wales has its own curriculum introduced recently; and Northern Ireland its own — so cross-border comparisons are frequently invalid.
