Data from the Early Childhood Longitudinal Survey-Birth Cohort are used to analyze the factors that lead to the reading readiness of children who participate in nonparental care the year prior to kindergarten (N = 4,550), with a specific focus on Latino children (N = 800). Stepwise multiple linear regression analysis demonstrates that reading scores are significantly influenced by the type of care provided the year prior to kindergarten, the caregiver's education and beliefs about kindergarten readiness, as well as access to books and a computer in the home. Furthermore, mother's level of education and marital status are important predictors of reading aptitude. (author abstract)
