Autism spectrum disorder (ASD) is a neurological and developmental disorder that affects the way people interact with others, learn and behave. Although autism can be diagnosed at any age, it is described as a "developmental disorder" because symptoms generally appear in the first two years of life. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), people with autism spectrum disorder often have problems communicating and interacting with others, limited interests, and repetitive behaviors. The latest version of the DSM-5 manual introduces innovations in differentiating the severity of autism spectrum disorders to better describe individual variation in symptom severity and support needs (Autism Spectrum Disorder Grade 1, Grade 2, or Grade 3). Although autism spectrum disorder is lifelong, treatments, supports and services can reduce or alleviate difficulties and improve daily functioning. People with autism spectrum disorder may have many distinct abilities, including the ability to learn quickly and retain information for long periods of time, excelling in math, science, music, or art. The aim of this work is to examine people's social attitudes about people with ASD and their inclusion in social and public life. The research was carried out using a questionnaire filled out by 302 respondents. Two hypotheses were put forward, which read: "Respondents of different levels of education have a statistically significantly different attitude towards people with ASD. Respondents with the highest education have the most positive attitude.", "Respondents who have children express a significantly more positive attitude towards people with ASD compared to people who do not have children.". The research results showed that both hypotheses were confirmed, i.e. people with a higher educational status have less negative attitudes towards people with ASD than people with a lower educational status. Also, it was confirmed that people with children count more positive attitudes about people with autism than people without children. It is necessary to present ASD in a positive way to the public and to educate people about the autism spectrum disorder and the importance of including people with autism in society.
