The impact of family mobility from domestic or international moves can be challenging for families. Some families adjust and other families experience crisis. For some families, relocation may be due to a job promotion and transfer, while for other families moving may be due to divorce, loss of employment or other stressful circumstances. Regardless of whether the family perceives relocation as positive or negative, moving places demands on families and consequently families experience varying degrees of transience. This article is based upon a qualitative research study about internationally mobile (IM) families managing relocation and transience and the place of international schooling in that process. 90 semi-structured interviews were conducted with 45 (IM) families at an international school in southern England. The study included an intervention that consisted of implementing a personal and social education (PSE) programme for families with adolescent children. Family involvement in PSE facilitated parent-adolescent communication at a critical transitional stage as IM teenagers who grow up "on the move" were experiencing complex emotional and social upheavals in relationships with their peers and their families. Although the focus of this study explored the experiences of a small sample of IM families, there are wider implications from the study. Family mobility presents an opportunity for schools to also work with families who experience domestic moves to ease the transition of children through pastoral care.
