By studying professional literature, analyzing interviews and using internet sources, the paper presents the importance of a school in nature for the purpose of child education. The school in nature should be available to all third and fourth grade students, and for that to happen, there is a need for cooperation between principals, teachers and local self-government. The theoretical part of the paper deals with the notion of field course teaching in Croatian education, and then describes the history of the school in nature in the world and in Croatia and the current organizational forms of school in nature in Croatia. The research part includes text analysis, internet resource analysis, and analysis of teachers testimony transactions. The results of the research of internet sources have shown that tourist agencies offer the highest offer for nature school in Istria, followed by Zagorje and northern Dalmatia. The analysis of transcripts of interviews with teachers from Zagreb, Zadar and Dubrovnik showed that local self-government support plays a major role in the implementation or non-implementation of the school in nature. The methodological part of the paper presents the nature school proposal for students of the fourth grade of the Zadar County, which would take place in Sljeme in the Red Cross House and last for 5 days.
