I was sorry to see you've had no replies to your post--it's the first thing that comes up when Googling "Florimont vs Lancy." Have you made any headway in your school search since October? I assume you've taken a few more steps in the intervening months.

We've learned recently that we'll be arriving in September 2018 too, working at the UN with 3- and 5-year-olds in tow, and are staring down the same choices as you were, with a fairly similar list of priorities. We're now scrambling to catch up with the folks who've had more time to plan their moves.

We have telephone interviews with both schools scheduled for the coming days, after which I'd be able to share my first impressions (though you're likely far ahead of us in the process by now).

Any thoughts/updates on how it's been going for you would be very helpful to the rest of us in the same sort of boat.

I'd recommend the public system if you want (1) your child to learn French (2) a high level of education.

There is assistance for children with no French, and I would also engage a tutor from http://ararep.ch/

Good luck.

I'll just also add we've had experiences with Ecolint which was good, and the L'ecole de Nations which I would give a big thumbs down to.

We liked both but ended up going with Florimont. Basically it came down to which "felt" better, and for us that was Florimont. We were initially attracted by the bilingual option at Lancy, but learned that the additional amount of formal language instruction meant that other things (I believe music, art) were displaced. In the end, though, we're leaving Geneva much earlier than expected, so all of it turns out to be moot! Happy to chat more, if you want to send me a message.
