Education in England is divided into private schools attended by 7% of children and state schools for 93%. State education includes nursery, primary, secondary, and tertiary levels. The National Curriculum sets common standards and subjects for primary and secondary schools. Key stages divide schooling into age groups. Core subjects are English, maths, and science, and other foundation subjects are also taught. Secondary schools can be community, voluntary, academy, or free schools. The sixth form caters to students aged 16-18 prior to university. OFSTED inspects state schools and each school has a governing body that oversees strategic matters.
