Both my pedagogical (from the university) counseler and the one from Pôle Emploi told me that I was not eligibile to "formation initiale", and that I could only continue studying in "formation continue", since I had already studied, and worked for more than two years. Many people told me the same.
Luckily, I did not listen to them, and still registered, successfully.
I think that many persons (including myself & many public education workers) have a poor understanding of this (admittedly unclear) part of the education code. From my understanding, everyone is eligible to "formation initiale", while some people in a specific situation are eligible to "formation continue", which has been misunderstood as meaning that people that are in this situation are also not eligible to "formation initiale".
