Down syndrome is a genetic disorder in which trisomy occurs on the 21st chromosome, that is, in the 21st chromosome pair, an extra chromosome appears, which causes various physical and mental difficulties in a person. People with Down syndrome have a certain degree of mental retardation and, therefore, different learning and concentration difficulties. From an early age, it is very important to intervene and involve a whole range of professional associates and doctors in the development of children with Down syndrome, so that they can successfully join the everyday life of their social community. This requires a lot of time, patience, but also love. Despite all the difficulties, it is possible to achieve enormous results and improve the quality of their lives. Children and people with Down syndrome can do everything that other people can, only that they learn and conclude in a different way, which is harder for us to understand. In order to include them in regular educational institutions, the process of inclusion is carried out, which means their inclusion in the regular education program where they have the same opportunities as other children, only with the adaptation of materials and the curriculum. Everyone can participate in the inclusion process, so volunteer engagements are one of the leading extracurricular forms of implementing the inclusion process of people with Down syndrome. The main goal of this thesis was to examine the attitudes of volunteers towards working with people with Down syndrome, as well as their attitudes towards Down syndrome in general. For the purpose of this research, their understanding of volunteering and Down syndrome was also examined, and in what way they were involved in the process of inclusion of people with Down syndrome within their social community through various forms of volunteer engagement in their volunteer centre/association
