Collaboration between non-governmental organisations (NGOs) and public institutions, in accordance with the new public governance model, may contribute to actions by such organisations on behalf of both the co-production and co-construction of social services. The aim of this article is to assess the role of selected traits of NGO leaders in determining the chances of collaboration between NGOs and rural gmina offices in central, postsocialist Poland. The authors present the results of studies on selected subjective determinants of such collaboration, in which 104 leaders of NGOs from 29 rural gminas participated. Five independent research tools were implemented. Logistic regression analysis was used to assess the role of selected traits of NGO leaders in determining the potential for collaboration between NGOs and rural gmina offices. The final model indicates that the potential for collaboration between an NGO and a rural gmina office increases alongside higher levels of education, social competences and locus of control and decreased control ideology among NGO leaders. On this basis, the authors formulate practical conclusions concerning the education of leaders of rural NGOs in post-socialist Poland.
