A secondary school describes an institution that provides secondary education and also usually includes the building where this takes place. Some secondary schools provide both lower secondary education and upper secondary education i.e. levels 2 and 3 of the ISCED scale, but these can also be provided in separate schools, as in the American middle and high school system. In the UK, elite public schools typically admit pupils between the ages of 13 and 18. UK state schools accommodate pupils between the ages of 11 to 18.
