 Well-being at school, a necessary health question to thrive 
CNESCO recently put forward a study regarding the correlation between the quality of the school experience and the quality of the learning showing the importance of student well-being. The pedagogical well-being, (defined as the adjustment of the student accompaniment to their psychoaffective needs, improves the quality of the school experience, allows the personal development and yields happiness from being at school (De la Garanderie, 2013). Our action research, in a shared view of well-being was focused on the student’s working comfort in Cycle 3, with the establishment of an experimental device whose objective was to take care of children, while supporting their teachers in this approach with accompaniment. A charter of pedagogical welfare (Loton, 2020), from the medical world, and translated into professional teaching practices suitable to the needs of each one, has allowed the implementation of a pedagogical accompaniment practice in regards to well-being. The collection of school experiences has been done by using a tool created specifically to measure the quality of experience of children: a Scale of Measurement of School Experiences (Habib et Bidal, 2016), has led to results that reveal an increase in personal development and validates the capacity of the welfare system put in place to produce educational well-being.
