The paper presents the results of the survey of the role of civil society organisations in the field of non-institutional education. The study was conducted on a sample of 91 organisations that have received financial support for projects and programs from the Ministry of science and education in the area of non-institutional education for children and youth in the past five years. The aim of the study was to gain a more detailed insight into the structure, specific areas and ways in which civil society organizations are operating in the field of non-institutional education and their contribution to the education. We also wanted to examine the frequency, nature and quality of cooperation with educational institutions, the structure of organisations and their employees, funding sources, obstacles to achieving goals, the impact on changes in the formal education system and the use of innovative learning and teaching methods. The results show that the organisations are active the most in the following areas: promotion of volunteering, education and rights of children and people with disabilities/developmental disabilities/chronic illnesses and the protection of young people's health, struggle against addiction and violence. 93,4% of the organisations in the sample cooperated in the implementation of projects with educational institutions, most often with primary schools. Furthermore, organisations are mostly satisfied with cooperation. Organisations are largely not active in criticising national education policy or in influencing education policies. Organisations see their main contributions to education in enriching educational content and curricula, as well as in the professional training of educators. For organisations in the sample, the biggest problem in their work is a lack of financial resources.
