This report analyzes data from three longitudinal datasets at the U.S. Department of Education's National Center for Education Statistics. It shows how children's access to arts education differs as they grow older, how access differs across subgroups of children, and how arts participation in childhood and adolescence is positively related to social-emotional attributes and academic outcomes.
