At age 6, they are enrolled in primary school ("école primaire") which is made up of six grades. The next level is secondary school ("école secondaire"), which is made up of seven grades. The intended age at graduation is 19 years. Graduates of secondary school can apply for universities or other institutions of higher learning, such as engineering schools or business schools.
