To promote high-quality development in preschool education and explore the relationship between preschool teachers' perceived organizational support and turnover intention, a survey was conducted among 932 preschool teachers in Guangdong Province. The findings reveal that preschool teachers' overall perceived organizational support score is at a high level, while their turnover intention score is slightly below average. This indicates that certain achievements have been made through the nation's implementation of measures to further deepen the reform of preschool education. With perceived organizational support serving as a protective factor against preschool teachers' turnover intention, this study further explores the relationship between these two variables. These research findings have practical significance for kindergartens in improving preschool teachers' work happiness and reducing turnover rates.
