Beginner teacher training was a concern for John Baptiste de La Salle, as it was for other pedagogues who preceded and succeeded him. La Salle was convinced of the importance of the teacher for the school to perform well. Despite the greater availability of means and resources today, this importance remains undoubtedly the same. Current times, however, challenge us to rethink the intuition of the Patron Saint of Teachers and to design training and accompanying processes for those who are just starting in the teaching profession so that the trialand- error principle and improvisation are not the road to find the best way to carry out their educational work.
