Research Findings: A structural equation model (SEM) and multiple indicators and multiple causes (MIMIC) model were used to test family factors, parent psychological well-being, parent-child home activity, and parent school involvement in relation to children's school achievement. Data for this study were drawn from the Early Childhood Longitudinal Study-Kindergarten (ECLS-K), conducted by the U.S. Department of Education's National Center for Education Statistics (NCES). The sample for this study was 1,100 Asian American kindergartners and their parents. Practice or Policy: The results of this study are as follows: (a) Family factors, especially parental education levels and family income, were significantly associated with Asian American students' school achievement; (b) parent-child home activity was significantly related to students' school achievement but in a negative direction; (c) parental school involvement was not found to be significant in predicting students' school achievement; (d) parental psychological well-being was significantly associated with both parent-child home activity and students' school achievement; (e) family income was significantly associated with parental psychological well-being, parental school involvement, and children's school achievement; and (f) family structure was not significantly associated with school achievement.
