Education is commonly and formally divided into stages such as preschool, primary school, secondary school and then college, university or apprenticeship. The methodology of teaching is called pedagogy.
A right to education has been recognized by some governments. At the global level, Article 13 of the United Nations’ 1966 International Covenant on Economic, Social and Cultural Rights recognizes the right of everyone to an education. Although education is compulsory in most places up to a certain age, attendance at school often isn’t, and a minority of parents choose home-schooling, sometimes with the assistance of modern electronic educational technology (also called e-learning). Education can take place in formal or informal settings.
