The National Curriculum sets out the various stages and subjects children will learn during their time at school. All maintained (state) schools must follow the National Curriculum. The National Curriculum itself is made up of 4 Key Stages, plus the Foundation Stage (education before reaching age 5).
Each child's progress is continually monitored throughout their educational history, however, formal monitoring takes place at the end of each Key Stage.
At the end of Key Stage 1, a child's progress is based on their teacher's assessment based on their performance throughout years 1 and 2. Some schools may run testing to assist with the assessment.
At the end of Key Stage 2 and 3, progress is based on teacher assessments and the outcomes of national testing. Testing at Key Stage 2 and 3 will also help to compare progress against targets.
Progress at the end of Key Stage 4 is based on the outcomes of GCSE examinations where pupils will sit examinations in a combination of compulsory and optional subjects.
Compulsory education ends at age 16.
At Key Stages 1 and 2 the statutory subjects that all pupils must study are art and design, design and technology, English, geography, history, information and communication technology, mathematics, music, physical education and science.
