<p>Evaluative research in Jewish education often adopts a “silver bullet” approach, attributing identity outcomes to single programs or interventions. This article advances an ecosystem framework that situates Jewish schooling, family upbringing, and peer networks within their wider communal and societal contexts. Drawing on hierarchical regression analyses of large-scale survey data (<i>n</i> = 21,260) from four Jewish diaspora communities, we find that the impact of Jewish education depends on its interaction with family background, social capital, and national setting. Jewish identity thus emerges as a cumulative and relational process rather than the product of discrete experiences. These findings underscore the limitations of single-country studies, which often generalize about Jewish identity formation without considering the structural and contextual differences that shape communal life in different national settings. The findings also extend sociological theories of social capital, cultural capital, and the life course, offering new insight into how educational, familial, and communal forces together sustain Jewish identity in diaspora.</p>
