The authors examined the concurrent associations of school-based parent involvement (PI), family sociocultural factors, and children's academic skills in a sample of 258 Chinese American children (5-9 years old) in immigrant families. Parents reported their American and Chinese orientations and family socioeconomic status (SES). Parents and teachers rated parents' school-based involvement, and children's English reading and mathematics calculation skills were assessed with standardized tests. Results of path analysis indicated that, controlling for SES, parents' American orientation was positively associated with their self-reported PI. Although parent- and teacher-reported PI were positively correlated with each other, only teacher-reported PI was positively associated with children's English reading. These findings support the benefits of school-based PI for Chinese immigrant children's English reading achievement. Results also highlight the need to consider differences between teachers' and parents' perceptions of PI in developing culturally sensitive interventions to encourage immigrant parents' school involvement.
