At schools that have a junior school, it is where a child will begin their education, usually in or before the year level preceding Year 1. Depending on the school, a child will move to the main primary school between the ages of 7 and 10.
In most primary schools, the junior primary is located within the same buildings and grounds as the primary school, although some junior schools are located on an adjacent or separate.
A junior school forms part of the local pattern of provision for primary education. Most junior schools cater for pupils moving from infant schools from the September following their seventh birthday. Pupils join in Year 3, and stay at the school for four years, leaving at the end of Year 6 when most pupils are aged 11. These four years form Key Stage 2 in the English education system. At the end of this time, most pupils will move to a secondary school.
In some areas of England, provision of education at this age is made in middle schools catering for pupils aged 8 to 12, or 9 to 13.
