There is a huge migration of Filipino early childhood education (ECE) teachers working abroad. Thus, this study explored the lived experiences of Filipino Early Childhood Education (ECE) teachers working abroad, focusing on how they adapt personally and professionally in foreign educational settings. Drawing on Acculturation Theory, the research aimed to understand the behavioral, identity, and value changes experienced by these teachers. Using a phenomenological qualitative design, five Filipino ECE teachers from diverse countries participated in in-depth interviews. Findings revealed significant changes in behavior, including professional flexibility and assertive communication, alongside evolving teacher identities marked by self-reliance and a global perspective. Additionally, shifts in values such as increased appreciation for diversity, mental well-being, and family collaboration were observed. These outcomes underscore the transformative impact of cross-cultural teaching on Filipino educators professional growth and personal development. The study concludes that working abroad fosters cultural competence, resilience, and reflective teaching practices among Filipino ECE teachers. Future research should examine the long-term effects of these experiences on professional growth and well-being, and educational institutions should develop support programs to enhance cultural adaptation and emotional resilience for overseas teachers.
