Parent involvement is a robust predictor of academic achievement, but little is known about school- and home-based involvement in immigrant families. Drawing on ecological theories, the present study examined contextual characteristics as predictors of parent involvement among Afro-Caribbean and Latino parents of young students in urban public schools. Socioeconomic disadvantage was associated with lower home-based involvement. Several factors were associated with higher involvement, including parents' connection to their culture of origin and to U.S. culture, engagement practices by teachers and parent--teacher ethnic consonance (for Latinos only). Findings have implications for promoting involvement among immigrant families of students in urban schools.
