Recent recommendations from experts such as the National Education Goals Panel (NEGP, 1998), and the National Research Council’s From Neurons to Neighborhoods (Shonkoff & Phillips, 2000), have pushed educators and researchers to think broadly about school readiness as encompassing more than cognitive development, and to include social-emotional and physical health in the definition (Fuligni & Brooks-Gunn, 2000). In recent years, there has been a growing policy focus on the notion of “Universal Preschool,” a movement that recognizes the importance of opportunities for learning for 3- and 4-year-olds, and the disparities in school readiness between children who enter kindergarten with some preschool experience and those who do not. Concurrently, changes in welfare requirements have meant that many mothers of young children have had to enter employment, education, or training in order to continue to receive welfare benefits.
