This study examines the prevalence of home-school match in childrearing beliefs and socialization practices (control and support) and their relation to ethnicity and readiness skills of children (n = 310) making the transition from publicly sponsored Pre-k to kindergarten. Home-school match was operationalized both as a continuous absolute measure and as categories of match or mismatch. Overall, home-school match was more prevalent than mismatch. However, the results corroborate previous ethnographic studies showing higher rates of home-school mismatch among African Americans and Latinos than Euro Americans. Controlling for race and socio-economic status, parents' beliefs and practices predicted readiness but teachers' did not. Absolute indicators of home-school differences were not related to kindergarten readiness. Directional indicators revealed that children attained greater skills when parents and teachers matched on child-centered beliefs, low control, and high support. Contrary to the cultural match hypothesis, home-school mismatch was associated with better outcomes than match in the case of adult-centered beliefs, control, and low support. (Contains 9 tables.)
