The teaching profession has been studied and discussed from a problem-oriented point of view and cultivated by a problem-oriented scientific tradition. Years of research have enabled a better understanding of difficult teaching conditions and teachers' ill-being; an ideological and scientific shift, however, appears necessary to enrich and broaden our present knowledge. One particular question arises: which determinants optimize teachers' professional well-being? In response, our study seeks to identify indicators that allow teachers to create, maintain or restore a state of professional well-being. Our research objective thus aims to describe teachers' indicators regarding the "optimal functioning" that characterizes professional well-being (Seligman, 2011). The research protocol targets physical education teachers insofar as they are now recognized as leaders and models for promoting healthy lifestyles in schools and communities (MEQ, 2001). The methodology involved 5 focus groups composed of 37 teachers from 7 regions of Quebec. As the findings indicate, this approach allowed us to paint an integrative portrait of teachers' indicators relative to professional well-being. Two categories have proved effective in terms of professional well-being: the first is Self and includes 4 variables: meaning, positive emotions, engagement and vitality; the second is Others and includes 3 sub-categories: students, colleagues and school administration. The sub-categories comprise 6 variables divided as follows: positive relationships, learning, collaboration, transfer (specifically for the two first sub-categories), followed by vision and valorization for the third sub-category.
