Lycée Xavier is an unofficial french school. It means the curriculum is not recognized by french education system. It is actually recognized by no institution. Students from Lycée Xavier need to take the final exam in high school having same status with home-school students... And can't receive any scholarship to study in France because the school is not an official one.
This is a nice little school set in a beautiful location. It is quite traditional in it's approach, but has a relaxed atmosphere. The kids I know that go there love it. It is a good alternative to the English speaking international schools and more reasonably priced.
