Ms Vidal is also organising master classes for gifted linguists: 40 Year 8 stdents will soon be taking a four-hour Saturday morning session in French at St Clement Danes School, Chorleywood. A similar session for Year 9 German students is being planned.
Nor is Ms Vidal, originally from Marseilles, daunted by the prospect of a shortage of staff. She recently advertised in Watford for foreigners who would like to teach: 60 came forward. "Whether you like it or not, this is the future," she says. "The people were not all trained, but we need to be creative."
