At the current pace of progress, the United States will not reach all preschoolers with public programs before the end of the 21st Century. Without national leadership, universal high-quality pre-K will remain a dream. This fact sheet sets out one vision for how that dream can become a reality, with the federal government offering states a 50-50 match for every dollar spent on high-quality pre-K for all children under 200 percent of the federal poverty level (FPL). We estimated the annual cost to the federal and state and local governments of a plan that enrolls all 3- and 4-year-olds under 200% of FPL in high-quality public pre-K within 20 years and all 3’s and 4’s in another 10 years.
