Loads of choices. A lot are in the western suburbs of Paris, which is where we are. Super fast RER into Paris and access to the greenery.
Choices depend on several factors,: are the company paying? British or American curriculum? Do you want your children to learn French? How long are you staying? Any special needs?
The BSP (British School of Paris) in Croissy is €€€ but if firm are paying, no problem. British curriculum and a real bubble. Don't expect your children to learn any real French. It's a great environment though and super for the parents as the social life is great. I've loads of friends there.
Malherbe International School in nearby and very beautiful Le Vésinet is a primary only school. We chose this for our DS because DH firm weren't paying fees, and Malherbe offers a 'self-funding' option. They also are bilingual: approx 30% of the British curriculum is taught in French. So a great soft landing into France.
The Lycee International is in Saint-Germain en Laye. They have British and American sections. Academic but a French state school .... think of them as a grammar.
Loads of other choices including ASP.
We've been here 2 years; son arrived from London with no French. He's now at a French bilingual middle school that also has a primary. If you think your children are resilient enough to go into this school and learn French, it's another option.
Feel free to pm me. There are Facebook groups that are very handy, particularly if you opt for the western suburbs. There is scouts, Cubs etc for both British and American groups and loads of activities.
I love it here.
