An infant school forms part of the local pattern of provision for primary education. In England and Wales infant schools cater for pupils aged 4 to 5 years in a reception class (equivalent to an American kindergarten). This year makes up the final part of the Foundation Stage, and is compulsory (unlike Nursery). Pupils then transfer to Year 1 in the September following their fifth birthday, and to Year 2 the following year. These two years form Key Stage 1 in the English education system. At the end of this time, most pupils will move to a linked junior school, although some may move to a through primary school.
In some areas of England, provision of education at this age is made in First schools catering for pupils aged up to 8 or 9.
