This paper deals with the topic of social inclusion of people with intellectual disabilities. The paper is based on the description and interpretation of facts and materials that are closely related to the topic of the paper. Social inclusion involves respecting people's differences and focusing on a person's capabilities and abilities rather than what that person cannot do. An inclusive approach in working with people with intellectual disabilities can be used in education, employment, social and public life of the person. Despite the large number of associations and organizations whose goal is the promotion of the social inclusion of people with intellectual disabilities, people with intellectual disabilities are still not fully accepted and included in society, public life, education and the business environment. The main obstacles to the social inclusion of people with intellectual disabilities are the negative attitudes of society, lack of available/adapted activities, lack of self-confidence among people with intellectual disabilities, lack of professional staff that would work with people with intellectual disabilities, lack of information by people without disabilities about capacity of people with intellectual disabilities and lack of information by people with intellectual disabilities about their rights.
