The aim of this study was to determine the readiness of Danish and Croatian preschool teachers for developing children's resilience and also to compare the results of these two groups. Theories from the field of stress, resilience, risk and protective factors have been used as a theoretical framework for this study. In this research participated 81 preschool teachers from different parts of Denmark and Croatia. The number of Danish preschool teachers was 41, and the number of Croatian preschool teachers was 40. In order to examine the differences between these two groups of teachers The Questionnaire of the Readiness of Preschool Teachers for Developing Children's Resilience was applied (Bouillet, Miljević-Riđički and Pavin Ivanec, 2014). The results showed that there are differences between these two groups in the factors of „Competences for developing children's resilience“ and „Institutional climate“. On these two factors Danish preschool teachers expressed greater agreement with the statements in comparison with Croatian preschool teachers. Furthermore, no difference were found between the two groups of teachers on the factors of „Supportive attitudes towards developing children’s resilience“, „Willingness to implement developing children’s resilience“ and „Conditions for the implementation of developing children’s resilience“. The studied literature indicates better working conditions in Denmark than in Croatia, in relation to the number of children and the number of teachers in educational groups, as well as greater investments in the training of preschool teachers in Denmark, compared to Croatia. Unexpectedly, as stated, respondents from Croatia nevertheless showed extremely positive attitudes in the area of willingness to implement developing children’s resilience and in the area of conditions for the implementation of developing children’s resilience, Croatian teachers were quite aware of the issues of encouraging resilience in children and they were interested in the topic, as well as their colleagues in Denmark.
