A secondary school is an organization that provides secondary education and the building where this takes place. Some secondary schools provide both lower secondary education and upper secondary education (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.
Secondary schools typically follow on from primary schools and prepare for vocational or tertiary education. Attendance is compulsory in most countries for students until the age of 16. The organisations, buildings, and terminology are more or less unique in each country.
