Objectives: The aim of this research is to examine parents' perception of discrimination against children with developmental disabilities and to analyse the relation between discrimination against children with developmental disabilities and the demographic data of the respondents. Study Design: The study was conducted as cross-sectional. Participants and Methods: 70 parents/guardians of children with developmental disabilities from Josip Matoš Elementary School Vukovar and the Association for People with Intellectual Disabilities "Golubica" Vukovar participated in the research. Results: The results of the conducted research showed that there is no statistically significant difference in the parents' perception of discrimination against children with developmental disabilities regarding the gender of the respondents. There is a statistically significant difference in parental perception of discrimination against children with developmental disabilities regarding age in the area of society's approach to children with developmental disabilities, and in the area of society's prejudices against children with developmental disabilities. Also, there is a statistically significant difference in parents' perception of discrimination against children with developmental disabilities in relation to the level of education. Parents with secondary school education experienced discrimination against their children with developmental disabilities in the field of quality of education and health care and in the area of society's approach to children with developmental disabilities. Conclusion: Based on the conducted research and the results obtained from the research, we can conclude that parents/guardians of children with developmental disabilities experience discrimination in certain areas of everyday life.
