Faced with multiple changes in education, teachers must adapt to the diversity of learner profiles now integrated into regular classes. Our study focuses on a two-pronged support system (group and individual) to support the professional development of school teachers. The creation of dialogical spaces has stimulated exchanges in addition of challenging ideas and values to build new benchmarks that guide the work. The results show that the support provided has encouraged the adoption of practices oriented towards inclusive education principles and (...) helped to develop a common vision within the school team.
