The "Tree of Affections" programme was created as part of the PNPSE and is now five years old, having been updated and improved every year. Its central purpose is to promote school success and educational inclusion. It is structured around four areas of intervention - students, school, family and community - through which multiple activities are organised for different audiences (students, teachers, operational assistants, technicians and families). The overall aim is to strengthen the socio-emotional skills of all members of the school community, with a special focus on students, in order to favour an educational and family environment that supports personal, relational and academic growth. In addition to these axes, there are also motivational activities for teachers, the implementation of an observational study and various psychological health literacy initiatives.
