This study explored the in-depth experiences of directors of public daycare centers under changed commissioning. Two rounds of individual interviews were conducted with eight directors of public childcare centers under changed commissioning in the Chungbuk and Gyeonggi regions. The findings revealed that the directors’ motivations for applying for changed commissioning reflected both their realistic considerations and their idealistic aspirations. The preparation process varied according to the individual's philosophy, experience, and competence. Preparation could be self-directed or supported by external assistance. During the initial phase, the directors faced un-systematized handovers, uncomfortable relationships with teachers and former directors, clashes with existing organizational cultures, and difficulties in building trust with parents. To normalize operations, directors implemented multi-faceted teacher support, restructured the organizational culture to be more collaborative and horizontal, expanded parental communication and participation, and gradually enhanced the curricula. These findings indicate that changed commissioning is a holistic process of reconstruction encompassing relationships, emotions, organizational culture, trust, and curricula. Efficient transitions require institutionalized and standardized handovers, pre-service training and mentoring for directors, and the sharing of information and case studies.
