This project will measure the degree to which parenting programs based in pediatric primary care can be effective in promoting language development and school readiness in at-risk young children. The study will represent a collaboration between the Department of Pediatrics at New York University School of Medicine - Bellevue Hospital Center, the Medical and Health Research Association of New York City, Inc., and the Center for Research on Culture, Development and Education at New York University Steinhardt School of Education. Initial funding was provided by NICHD for 4 years. NICHD provided 5 additional years of competing renewal funding beginning in July, 2010.
