Abstract Background As inclusive education is being implemented nationwide in Lithuania, various attitudes towards education of children with disabilities in general schools are observed. We aimed to assess the attitudes of heads of general schools towards the provision of education to children with disabilities in general education schools of Lithuania. Methods Heads of all schools in the Lithuanian capital and its surrounding municipalities implementing general education programmes were invited to take part in this study. 115 persons agreed to participate and completed the questionnaire in spring of 2024. The distribution of the respondents by their answers to the questions about the attitudes towards the provision of inclusive education was compared according to gender, age, education level, work experience, school location (municipality), language of education, type of school, subordination, number of pupils, teachers, teaching assistants and pupils with disabilities. Results The most frequently indicated barriers for inclusive education provision were the lack of specialists, compensatory measures, methodological tools, adaptation of the physical environment, and high number of pupils (87.8%, 84.3%, 78.8% and 76.6% respectively). Attitudes of the respondents were similar in most of the cases when compared according to socio-demographic factors (p more than 0.05). Negative attitudes towards the possibilities for provision of inclusive education were more common among respondents from schools with fewer pupils and higher relative number of teachers, positive attitudes - among those from schools located in municipalities with lower number of residents and schools with more teaching assistants (p less than 0.05). Conclusions While attitudes of heads of general schools towards the provision of inclusive education for children with disabilities are similar in most of the cases, negative attitudes are more common among those from schools with fewer pupils and more teachers. Key messages • While attitudes of heads of general schools towards the inclusive education are similar in most of the cases, negative attitudes are more common among those from smaller schools. • Higher number of teaching assistants and smaller municipalities were associated with positive attitudes towards inclusive education of children with disabilies in general schools.
