A primary school is an institution where children receive the first stage of compulsory education known as primary or elementary education. Primary school is the preferred term in the United Kingdom and many Commonwealth Nations, and in most publications of the United Nations Educational, Scientific, and Cultural Organization (UNESCO). In some countries, and especially in North America, the term elementary school is preferred. Children generally attend primary school from around the age of four or five until the age of eleven or twelve.
