This study examines the community-building and community-preserving functions of rural small schools through an analysis of international and Hungarian literature. Although definitions of “small school” vary across countries, these institutions share the characteristic of operating in small settlements and fulfilling not only educational but also important social and cultural roles. Rural schools function as multidimensional community spaces that support everyday interactions, strengthen social capital – trust, cooperation, and social networks – and contribute to the maintenance of local identity. International research shows that school closures often lead to weakened social cohesion, increased outmigration, and economic decline. Hungarian studies similarly highlight that rural schools are key institutions of local communities, and their disappearance may result in the long-term erosion of social and cultural structures. The study argues that sustaining small rural schools is not merely an educational policy concern but a crucial aspect of functioning of local communities and local resilience.
