International field visits aim to provide transformative learning experiences that stimulate the professional development of staff, but outcomes may vary among programs. In this mixed-methods study, we investigated the transformative learning experiences of Dutch and German professionals (n = 28) from early childhood education and care (ECEC) who participated in a blended intensive exchange program with mutual field visits. Our findings indicate a transformative learning process in which the participants developed an awareness of cultural differences, moved to understanding these differences and, occasionally, to adaptation of new professional beliefs related to the interaction with young children. However, it proved difficult to implement new practices in the own centers after the program. We discuss how international exchange programs may foster transformative learning and the professional development of ECEC staff.
