Voltaire is still a vary new school and not very stable in terms of teaching methods organization and management
They basically lack long term vision and they are not fully approved by the relevant French authorities
They are thinking of teaching the international baccalaureate instead of the freanch one

The director was recently fired the school remained I chaos fee many weeks
Teachers are leaving without notice

New director still unable to catch up with the events
A total failure in terms of communication with parents
But may be on the very long term they could improve the French system remains quite good particularly for maths and physics
