The aim of this study was to investigate parents' perceptions of forest school. Qualitative research was adopted as a research design. The study was carried out with parents who have children enrolled in the forest school. Thirty-nine parents participated in this study. Their perceptions about forest school were investigated through interviews. In the interview schedule, five open-ended questions were asked parents to obtain their perceptions of forest school. A content analysis technique was used to interpret data. According to parents, a forest school is a place where children have positive feelings, discover nature and life and interact with nature. Their reasons for preferring the forest school were listed as nature as a learning environment, the role of nature in wellbeing, education philosophy, and staff characteristics. Findings also revealed that parents consider children's increasing interest in environmental issues in terms of environmental awareness and knowledge; social-emotional development in terms of enhancement in self-confidence, and taking responsibility; motor development in terms of physical strength and speed; cognitive development in terms of inquiry skills.
