The first-ever report card on America's youngest students finds that most come prepared to learn. Nearly all children entering kindergarten - 94 percent - can count to ten, and two out of three can recite their ABC's, reports the U.S. Department of Education in study, America's Kindergartners. The study of 22,000 youngsters will continue for the next six years as the department tracks their progress through elementary school. While 90 percent of parents say their little ones make friends often or very often, one out of three admits that their child argues with others just as frequently. The report also highlights problems facing some tykes: Children in poverty, single-parent homes, and non-English-speaking families are less likely to be read to at home and so score lower on cognitive skills.
