An extensive longitudinal study examining the enactment of Jordan's Education Reform for Knowledge Economy (ERfKE) policy in public schools uncovered the pervasive influence of Al-Faza'a leadership, which is deeply rooted in tribal values of solidarity and kinship. This article analyses Al-Faza'a leadership as a culturally potent force that profoundly challenges policy change for education reform. Through a sociological study guided by Bourdieu's theory of practice, our findings reveal Al-Faza'a leadership as a distinctive form of illusio that is all the more powerful when intertwined with the doxa of Sheikhocracy. We illustrate how Al-Faza'a leadership embodies a persistent reproductive habitus, obstructing ERfKE's transformative potential and exemplifying resistance to externally imposed and culturally ill-suited reform agendas in Jordan's schools. By dissecting nuanced sociocultural dynamics shaping leadership practices, the article focuses on the experiences and perspectives of public school principals charged with policy enactment. It illuminates embedded cultural practices within schools and the Ministry of Education that are steeped in long-held traditions and beliefs which undermine policy objectives. This grounded theory-building study highlights the unsuitability of imported policy ideals that assume universal applicability and emphasizes the necessity of culturally sensitive approaches to education policymaking, policy enactment, and, hence, to education reform.
