Yvelines: in the private sector, there is also a shortage of teachers. The diocesan directorate of Catholic education in Yvelines, which manages 72 establishments, offers parents immersion days.

“I don't pay 5,000 euros for my children to face teachers without training or diplomas. Teacher, it's a job in its own right," says a parent of two students from the Blanche-de-Castille college, in Chesnay-Rocquencourt.
