Young children follow a fairly consistent pattern in their acquisition of language. This pattern is important because language develops rapidly and has been shown to affect later school readiness. A study published in the Journal of Applied Developmental Psychology, examines for the first time how the quality of childcare affects the development of specific language components. The study is unique in that participants were demographically homogeneous--all were white children of dual earner parents who had some level of higher education and were of middle income. In every measurement used, children in higher quality childcare significantly outperformed those in lower quality childcare and acquired key markers at a more rapid rate over time. This report summarizes the study's methodology and conclusions. [This FPG Snapshot was produced by the FPG Child Development Institute at the University of North Carolina at Chapel Hill.]
