The United States has historically undervalued its youngest children. Programs for those younger than five are generally weaker, facilities less adequate and financial support from government sources less sufficient. While much is said these days about leaving no child behind, not enough is done to keep more youngsters in the race for life’s blessings. The outcomes of efforts to implement universal pre-kindergarten (UPK)-one of the most important elements in this pursuit-represent a barometer of children’s status.
