Research has found disparities in young children's development across income groups. A positive association between high-quality early care and education and the school readiness of children in low-income families has also been demonstrated. This study uses linked administrative data from Maryland to examine the variations in school readiness associated with different types of subsidized child care, and with dual enrollment in subsidized child care and state pre-kindergarten or Head Start. Using multivariate methods, we analyze linked subsidy administrative data and portfolio-based kindergarten school readiness assessment data to estimate the probability of children's school readiness in three domains: personal and social development, language and literacy, and mathematical thinking. Compared to children in subsidized family child care or informal care, those in subsidized center care are more likely to be rated as fully ready to learn on the two pre-academic domains. Regardless of type of subsidized care used, enrollment in pre-kindergarten, but not Head Start, during the year prior to kindergarten is strongly associated with being academically ready for kindergarten. No statistically significant associations are found between type of subsidized care, pre-kindergarten enrollment, or Head Start and assessments of children's personal/social development.
