Integrated education in Poland has been implemented since 1993. This alternative form of education very quickly resulted in an increased number of integrated classes in mainstream schools and a decreased percentage of students with disabilities in segregated education. Research indicates that the process of "opening of society to disability" is progressing. Despite the fact that the functioning of individuals with disabilities in the system of integrated education was investigated mainly through research conducted among teachers and students, there were not many studies indicating parents' attitudes towards the implementation of that idea. Therefore, the main purpose of this paper is to describe the results of research on parents' perceptions of integrated education in Poland. The presented article illustrates parents' points of view regarding benefits of integrated education for children with disabilities as well as their peers without disabilities. Moreover, it depicts levels of parents' satisfaction with integrated education. Findings revealed that 92 percent of parents, whose children had disabilities, were "very satisfied" and 8 percent of them were "fairly satisfied". On the other hand, 84 percent of parents with children without disabilities were "very satisfied" and 16 percent were "fairly satisfied".
