We are looking for an IB school in France where the language of instruction is English and that offers the option of boarding or homestay. This is for a 15-year-old girl who lives in Barcelona, Spain and has followed the British system of education. She is fluent in English, Spanish and Catalan but has a low intermediate level of French, so she wouldn't be able to do her studies in French.
I've seen some good reviews here for the IBS of Provence and the Jeannine Manuel in Lille, but they were from 5-10 years ago and I wonder if anyone has more recent experience with these or other schools.
Thanks for your help.
