Successful inclusive education requires school transformations and changes to the education system. In Portugal new legislation passed in 2018 (Decree-law 54/2018) brought a new perspective in inclusive education for all educational agents. Three years later, it is essential that the legislation is evaluated by the teachers implementing it. Forty-three primary and secondary school teachers and two coordinators of multidisciplinary teams providing inclusive education support were the participants of our study. The data collection instruments were a questionnaire and interviews. This study values the participants' narratives, highlighting the new concepts and attitudes required for the implementation of the new inclusive education legal framework in Portugal. The results of the thematic analysis were organized around four key themes: (1) Theoretical representations; (2) Practices; (3) Challenges; and (4) Training. It is also worth noting the notions of collaborative work, the need for reflective teachers and the development of learning communities to support the implementation of the new legislation.
