In which subjects are her degree and master’s degree? If she wants to teach English as a vacataire she should make herself known to the person in charge of vacataires at the Rectorat (ring up and ask for the person in charge of vacataires) what is her French like?
If she wants to teach other than casually for the state or private schools recognised by the state she will need to do the capes or the capep, which are competitive exams ie they take the first however many they need.
There is a written part covering translation into and out of English and a lit paper and a linguistics paper and a paper on being a civil servant and behaving in a responsible and appropriate manner - I think that’s it. If you get through that then you go on to the orals.
You then have a year of tuition and teaching practice and if the inspectors and your tutor and your head all have a positive opinion of you, you are confirmed as a qualified teacher and can be sent anywhere in France, because you will be a fonctionnaire d’état and, therefore, deployable anywhere in France.
If she wants to go down this route she should get her skates on as the cut-off date for online applications ( ie for entering the competition) is the 13th of October. The first actual exams are in february I think, the Rectorat site will have a link to them anyway. She will need all her certificates in triplicate, obviously. If she gets through ( and there’s no reason she shouldn’t) she’ll start next September.
You need to be more active with the Rectorat, they are victims of funding cuts as we all are and have a zillion people to sort out. Get on the telephone and keep on until you have someone to talk to!
Please don’t hesitate to ask if you have further questions, I’ll do my best to answer them.
