Building on prior research, this study examines whether the association between classroom age composition and childrenĄ¯s learning and development vary based on classroom quality and teacher characteristics using a subset of the Family and Child Experiences Survey (FACES), a nationally representative sample of 3- and 4-year-old children attending Head Start (n = 2,829). Results revealed that the association between age composition and childrenĄ¯s academic skills was dependent on classroom quality and that classroom quality was less predictive of childrenĄ¯s skills in mixed-age classrooms. Teacher education but not experience also moderated the influence of age composition such that mixed-age classrooms taught by a teacher with higher education were not associated with decreased literacy gains among older children %K age composition %K classroom quality %K teacher experience and education %K Head Start %K FACES 2009 %U https://journals.sagepub.com/doi/full/10.1177/2332858418758300
