In Croatia, the emphasis on the implementation of integration and inclusion is strong, the importance of cooperation of a special and regular educational system is recognized as its essential element, but there are no works that study this cooperation in practice. Therefore, the aim of this research was to examine the attitudes of employees of the selected Center for Education and teachers and professional associates of nearby regular primary schools about the potential for possible strengthening of cooperation between the regular and special educational system. The research used a qualitative methodology, i.e. the interview method. The results show that the greatest space for progress in cooperation is seen in the increase in the number of professional associates in regular schools who will recognize the needs of their colleagues and students and seek help from the Center for Education, enable more frequent contact of both student populations, which would encourage tolerance and sensitization of students of orderly development towards students with disabilities. Furthermore, the potential for strengthening cooperation is seen in the increase in the number of professional associates in the Center for Education who could help teachers in professional development of teachers, cooperation with parents and in achieving better academic results of students. Cooperation could be strengthened by associations that would launch various events and manifestations that would promote equality and equality and further encourage the creation of an inclusive society.
