In France, secondary education is in two stages:Collèges cater for the first four years of secondary education from the ages of 11 to 15. Lycées provide a three-year course of further secondary education for children between the ages of 15 and 18. Pupils are prepared for the baccalauréat, which can lead to higher education studies or directly to professional life. There are three main types of baccalauréat: the baccalauréat général, baccalauréat technologique and baccalauréat professionnel.

Secondary education or post-primary education covers two phases on the International Standard Classification of Education scale. Level 2 or lower secondary education is considered the second and final phase of basic education, and level 3 upper secondary education or senior 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. In most countries secondary education is compulsory, at least until the age of 16. Children typically enter the lower secondary phase around age 12. Compulsory education sometimes extends to age 20.
