Existing literature presents a fragmented and negative account of international family transitions. This longitudinal study focuses on the contemporaneous experiences of internationally mobile families during their transitions to a new country and international school, drawing on Multiple and Multi-dimensional Transitions (MMT) Theory. The study adopted a small-scale, multiple case study design and focused on the experiences of primary aged children and their parents over the period of one year from July 2019 to July 2020. The findings, presented here as a cross-section, revealed that participants navigated multiple, complex transitions across several domains and contexts on a daily basis and that their transition experiences were largely positive. This study challenges previous chronological models of international transitions and demonstrates that through the application of MMT theory, international family transitions are best understood as ongoing, complex, and multi-dimensional processes.
