This study concerns the professional learnings in professional Master 2 within the department of sciences of the education at the University of Toulouse II Mirail. The objective is to enlighten the construction of an emergent professionalism to the students during the year of the training and to characterize the process of support of the director of the memoire and the professional referent. In the context of a professional training, we opted for a longitudinal methodology, by means of semi-directive interviews, allowing to follow our trainees over the year of training. These interviews bring to light the construction of an emergent professionalism by questioning the elements which participate in this construction. All results confirm that in this Master’s degree the students-trainees lived a very enriching work experience for their professional development especially during professional internship. This experience allows to discover and practice directly in the work environment which is expected in the future and to open the door on the professional world. The emergent professionalism to most of the students trainees of 5th year of university (professional Master 2) preparing to work for a company is observable at the end of this training. The identical, operating dimensions with the professional skills and the ethical dimension are present in the process of construction of this professionalism. On the other hand, for most of the students-trainees their professionalism always remains to develop and to improve during all the professional life.
