Recent discussions have centered around the protection of educational activities. This study, part of that discourse, explores the collaborative relationships among schools, families, and local communities, focusing on teachers' collaboration and communication. Analysis of teacher data from the Seoul Teacher Cohort Study confirms the urgent recognition of educational activity protection, especially in elementary schools. Positive perceptions of protection were linked to teachers forming collaborative relationships with parents and the local community. Leadership and communication by school administrators also positively influenced protection perceptions. However, the collaborative culture among school members, as perceived by teachers, showed no correlation with educational activity protection. Furthermore, differences were observed in the correlations among variables based on school levels and types of high schools. These results suggest that inherent characteristics specific to each school level influence educational activity protection, indicating the need for differentiated approaches based on school levels and types of high schools. Additionally, the results emphasize the need to redefine the educational community and highlight the utility of the concept of co-production in exploring collaborative relationships within educational communities.
