This study was conducted to determine the attitudes of teachers concerning inclusion in schools all over Serbia. The respondents were teachers of different subjects who were tasked to anonymously complete the provided closed-type questionnaire (970 respondents). Primary and secondary school teachers from urban and rural areas of the Republic of Serbia participated in the research. The results indicate that the teachers are supportive of inclusion. Despite significant differences in respondents' answers, the results of the research show that there are many similarities in teacher responses toward inclusive education. The results show that it is still necessary to work on the implementation of inclusive education in Serbia, especially to educate the teaching staff and involve experts in the planning and development of individual educational plans.
