The initial professional training is essential to become a teacher in education, but a major significance is the continuous improvement of the teacher, in the field of education, in order to permanently adapt to the innovative changes in the instructional process of the students, in general, and in particular to the challenges posed by the inclusion of students with special educational needs in general education schools. The continuous improvement of teachers contributes to their professional development and to the acquisition of competences in the targeted field, and the theoretical and practical acquisitions assimilated following participation in these training courses, will be transferred to the students in the classroom, to other teaching staff, through events to disseminate the knowledge they possess, to promote the sustainability of the respective project/program. Another aspect to be addressed in this article is the fact that mass education institutions must ensure access and participation in education for all children, regardless of the special needs they claim in their educational approach. Therefore, those that are transformed into inclusive schools, must also take into account the continuous improvement of the teaching staff who will practice inclusive education in the classroom, in order to favor the development and implementation of an effective inclusion process for students with special educational needs.
