1) You sign up and do your code de la route training and test.
2) After that you get 20 hours minimum of on the road driving tuition.
3) Then you get to do 1000 km of accompanied drivign with your folks.
4) A meeting to review progress.
5) A further 2000 km of accompanied driving.
6) A final meeting to review progress.
7) Driving test.

The code de la route tuition. He can only possibly do classes on Wednesday afternoon or Saturday morning.
Now the good news :
Both Pat and I can accompany his driving.
There's no reason why our British driving licences should prevent us doing this.
