<P> Secondary education covers two phases on the International Standard Classification of Education scale . Level 2 or lower secondary education (less common junior secondary education) is considered the second and final phase of basic education, and level 3 (upper) secondary education is the stage before tertiary education . Every country aims to provide basic education, but the systems and terminology remain unique to them . Secondary education typically takes place after six years of primary education and is followed by higher education, vocational education or employment . Like primary education, in most countries secondary education is compulsory, at least until the age of 16 . Children typically enter the lower secondary phase around age 11 . Compulsory education sometimes extends to age 19 . </P> <P> Since 1989 education has been seen as a basic human right for a child; Article 28, of the Convention on the Rights of the Child states that primary education should be free and compulsory while different forms of secondary education, including general and vocational education, should be available and accessible to every child . The terminology has proved difficult, and there was no universal definition before ISCED divided the period between primary education and university into junior secondary education and upper secondary education . </P>
