This paper offers a cultural assets model for supporting school effectiveness that moves beyond the deficit and difference approaches of the twentieth century. The model incorporates the capacity to identify contemporary cultural assets, and support cultural continuity, cultural diversity and cultural resilience during change. Undertaking concept-centric analysis, the reconceptualised understanding of contemporary cultural assets informs the construction of schools as cultural hubs, and reveals seven benefits that enhance asset-based approaches to school effectiveness. The model incorporates multigenerational flows of influence, community cultural activities, a communication conduit, and glocalised interactions. An empirical analysis of evidence advances the model's sociocultural view of effective schools; provides opportunities to extend research beyond minority studies; and establishes the importance of cultural assets in secure base leadership for developing schools as dynamic organisations.
