Inlingua. I got my best experiences for about any language there.

Migros also gives lessons, but I've got negative feedback from one of my own French students (I'm not a professional, and you're looking for a school )

IFAGE isn't bad, and the prices are the lowest because it's related to the government services: www.ifage.ch

Good luck.

Inlingua only for adults...

I don’t think there is such a thing as a “best school”.  They all have advantages and drawbacks.

There’s much to be said for making an assessment of your particular needs and motivations – why and for what reason do you want to learn French?  How much time can you really give to a sustained effort?  How much can you afford to spend?

Then try to dovetail your expectation with what’s on offer.  Ask lots of questions before you commit to a long-term arrangement.

Also be aware that some schools aim to get pupils through exams, cramming them on  the type of questions that are regularly set.  This might give you a piece of paper, but the method only teaches you how to answer  exam questions, it doesn’t explain how you can use and apply what you’re learning in context.

If your goal is to be at ease in society,  follow the news on TV and in the Press, generally feel more at home, you could be better off with  private tuition that is geared to your ability and interests.

But there, again, ask around for recommendations.  No one teacher can be a be-all to everyone.

Best wishes, R.

1) migros ecole Geneve is the most reasonable

2) Supercomm.ch if you are looking for a private tutor - I /my office use this one

Best to avoid all the schools and find a private teacher if possible. Look for someone with experience who seems organised.
