The current national curriculum programmes of study for mathematics at key stages 3 and 4 have been disapplied with effect from 1 September 2013 and are no longer statutory. This means that schools are free to develop their own curriculums for mathematics that best meet the needs of their pupils, in preparation for the introduction of the new national curriculum from September 2014. Further details are available via the link on this page.
Mathematics remains a compulsory national curriculum subject at all four key stages. New statutory programmes of study will be introduced from September 2014 for key stages 1 to 3, and September 2014 for key stage 4.
