Secondary education typically takes place after six years of primary education and is followed by higher education, vocational education or employment. In Algeria, secondary school starts after obtaining the BEM (Brevet d'Enseignement Moyen) (Middle School Certificate), and ends by getting the Baccalaureate that exclusively grants access to national universities.
