In the context of martial law in Ukraine, the educational sector has faced unprecedented challenges, particularly in the realm of preschool education. This paper presents a case study of the Zakarpattia Institute of Postgraduate Pedagogical Education and its rapid response to transform its curriculum to support preschool educators in these trying times. Through a comprehensive review of the curriculum changes, the study documents how the Institute has tailored its educational offerings to foster peace, cultivate a culture of peace and tolerance, and empower educators with critical thinking skills necessary for decision-making in crisis conditions. The paper explores the significant shifts in teaching strategies, content delivery, and psychological support mechanisms that have been implemented to address the pressing needs of educators. These adaptations are crucial not only for immediate conflict resolution but also for the long-term objective of building a peaceful society. By enhancing the quality of education for teachers, the study underscores the Institute’s role in shaping a future that is resilient, educated, and peace-oriented for Ukraine and beyond.
