Education systems worldwide have been disrupted by events such as pandemics, natural disasters, armed conflicts, and rapid technological advancements. During these periods, frontline teachers must continue their teaching duties under challenging and uncertain conditions. Educator resilience is therefore essential to ensure that learning continues without major interruption. This paper reviews secondary sources to examine how educators respond to and manage educational disruptions. The analysis shows that resilience develops over time and is influenced by multiple factors rather than being a fixed personal trait. Individual commitment, emotional strength, and the ability to adapt to new teaching methods contribute to resilience. Support from peers, school leadership, and local communities further enables educators to manage challenges. Institutions play a critical role by providing professional development opportunities, digital tools, and clear leadership. Persistent challenges, including increased workload, emotional strain, infrastructure gaps, and unequal access to resources, particularly in disadvantaged settings, remain significant barriers. The paper concludes that strengthening educator resilience requires coordinated efforts from individuals, institutions, and policymakers to better prepare education systems for future disruptions.
