This research aims to determine the views of teachers working in primary and secondary schools, with and without experience of inclusion. While deciding on the educational environment of individuals with special educational needs, it is aimed to determine the environment where the educational needs of the student are met in the best way and where they will receive education together with their normally developing peers as much as possible. This decision is taken from the least restrictive environment to the most restrictive environment principle. Inclusion practices expressing education in general education classrooms express the least restrictive environment. According to the MoNE 2022 statistics, 357,319 students continue to integrate. Quantitative research methods were used to determine the views of teachers working with these students on inclusion, and a total of 307 teachers were studied. The Sentiments, Attitudes, and Concerns About Inclusive Education-SACIE, developed by Loreman et al. (2007), and its Turkish translation, the Thoughts, Attitudes, and Concerns about Inclusive Education Scale, developed by Cansz and Cansz (2018), were used to determine teachers' opinions. The study's results indicate that women instructors are more optimistic than their male counterparts and that experiencing inclusion and getting instruction for inclusion reduces anxiety.
