Research Findings: This study examined correlates of parents' reported school engagement in an ethnically diverse, rural sample (N = 346) of parents and teachers in kindergarten through Grade 2. Of particular interest were role expectations and family-school relationships in American Indian families, who historically have been marginalized by schools. In terms of role expectations, parents and teachers agreed that they should support each other's roles, parents should have more responsibility than schools for teaching social skills, and families and schools should have shared responsibility for children's academic success. Teachers had higher expectations than parents for parent engagement, which in turn was greater when parent-teacher communication was more frequent and the school climate was more welcoming. American Indian parents more strongly endorsed a separation of family and school roles and felt less welcomed at school; ethnicity moderated correlates of reported parent engagement. Practice or Policy: These findings have practical promise given that parent-teacher communication, school climate, and role expectations are more easily altered than are structural barriers that also may hinder parents' involvement in supporting their children's early education.
