The report finds that the South leads the rest of the nation in Pre-Kindergarten (Pre-K) enrollment and quality today and identifies Pre-K as the region’s primary “comparative advantage” in efforts to catch up with the rest of the nation in education. The report documents the various economic and educational gains that the South can realize over time if states expand their investments in state-supported, high-quality Pre-K programs for three- and four-year old children in the state. The report includes the findings of several studies undertaken during the last five years on both learning gains and cost-benefit ratios from Pre-K programs in different Southern states. The report also analyzes the uneven development of Pre-K within the South and identifies common challenges that Southern states will face in taking Pre-K to scale across the region.
