title: Timing of high-quality child care and cognitive, language, and preacademic development.
abstract: The effects of high- versus low-quality child care during 2 developmental periods (infant-toddlerhood and preschool) were examined using data from the National Institute of Child Health and Human Development Study of Early Child Care. Propensity score matching was used to account for differences in families who used different combinations of child care quality during the 2 developmental periods. Findings indicated that cognitive, language, and preacademic skills prior to school entry were highest among children who experienced high-quality care in both the infant-toddler and preschool periods, somewhat lower among children who experienced high-quality child care during only 1 of these periods, and lowest among children who experienced low-quality care during both periods. Irrespective of the care received during infancy-toddlerhood, high-quality preschool care was related to better language and preacademic outcomes at the end of the preschool period; high-quality infant-toddler care, irrespective of preschool care, was related to better memory skills at the end of the preschool period.
