Actually, it's more complex than this in France.
There is 5 systems:
- depending of the Ministry of Eduction :
- for toddlers : maternelle (3-6 yo)
- Primary : CP (6 yo, primary), CE1 (elementary 1), CE2, CM1 (middle 1), CM2
- Secondary :
- College (not the US one!) : 6th (~11 yo), 5th, 4th, 3th (with exam at the end)
- Lycée : 2nd (~15 yo), 1st, Terminal (with 'Baccalauréat' exam at the end)
then depending of Ministry of Research : University or Post BAC schools
However, I think that in some other french-talking countries (Belgium, Swissland) they did it simpler
