Hi Actually in my experience, all are welcome to the summer schools. My children go to 'summer school' every school holiday whilst I work. There are no formal lessons but the kids have a great time doing lots of different things - crafts, games, fishing, trips to riding schools, lakes, fishing, ice skating, adventure parks, swimming, cinema etc. The projects are run by the Mairie and so are subsidised. Our summer school charges 10€ per child per day, which includes all their outings and food. I have a friend who came to stay for two weeks during the summer and her daughter went along with my two kids. Even her lack of French wasn't a problem. The co-ordinators normally prefer a bit of notice so that they can ensure their staffing levels are sufficient for extra children but that seems to be the only criteria. So, do make enquiries - summer can be long and very boring for kids with not enough to do - what an excellent way to make new friends and learn the language.
