Hi I'm not sure about international schools but I know of a private school in Draria,Algiers it's called Ecole la meilleure generation (best generation ). They have classes from reception all the way to year 9 as well as a nursery. If you require any more information I will be more than happy to help.
Hi Imen, Alexandre Du Mas, is a French school that usually accepts students from all over the world. They do however follow the French curricular. You could always try the French school for diplomats, but then I have no idea who you can contact to make that happen, besides they also follow the French program. Different books but French. There was an English school called Isa (international school of Algeria) I think. They were situated in Hydra. A private one, all English. Not sure if American or British, I'd have to check if they're still operating. Hope it helps and best wishes. M.
