<p>I don’t actually disagree with mathyone as much as my comments might indicate, but I do think there are some inaccurate statistics that are are being thrown on the table, mostly in support of your statement that up to 70% of kindergarteners have attended preschool, and that therefore, kindergarteners do not need to spend much time on socialization skills, or on learning cooperation and other soft, nonacademic "skills.</p>
<p>The vast majority of kindergarteners are five years old. The age at which a child may register for kindergarten varies from state to state. </p>
<p><a href=“Standarized Testing - Education - Schools - Test Scores - The New York Times”>http://www.nytimes.com/2007/06/03/magazine/03kindergarten-t.html</a> states that “The birthday cutoffs span six months, from Indiana, where a child must turn 5 by July 1 of the year he enters kindergarten, to Connecticut, where he must turn 5 by Jan. 1 of his kindergarten year.”</p>
<p>So it is appropriate to look at preschool statistics through age four, since most children start kindergarten when they are five. (Some may start at age six, and I did not look that percentage up.</p>
<p>I am using statistics from Child Trends, which is a nonprofit research group. According to Child Trends</p>
<p><a href=“Home - Child Trends – ChildTrends”>Home - Child Trends – ChildTrends;
<p>Among those children not yet enrolled in kindergarten, the percentage of three- to five-year olds enrolled in full-day prekindergarten and preschool programs increased from 21 percent in 1994 to 26 percent in 2012. The percentage of young children enrolled in part-day prekindergarten and preschool programs did not change significantly between 1994 and 2012, and was at 27 percent in 2012 - See more at: <a href=“Home - Child Trends – ChildTrends”>Home - Child Trends – ChildTrends;
<p>Preschool participation is roughly 53% of three to five year olds. (26 plus 27 percent).</p>
<p>That leaves a large number of children who have not attended preschool prior to kindergarten. And while many children attend some type of daycare prior to kindergarten, daycare includes being cared for by family members, sitters, small home based daycares, etc. Not every child has experience in daycare centers.</p>
<p>In 2011, 49 percent of children ages 0–4 with employed mothers were primarily cared for by a relative—their father, grandparent, sibling, other relative, or mother— while she worked. This is not statistically different from the percentages in 2010 and 2005. Twenty-four percent spent the most amount of time in a center-based arrangement (day care, nursery school, preschool, or Head Start). Thirteen percent were primarily cared for by a nonrelative in a home-based environment, such as care from a family day care provider, nanny, babysitter, or au pair.
The rate of care by fathers was between 15 and 16 percent in 1985 and 1988, increased to 20 percent in 1991, and settled between 16 and 18 percent from 1993 to 2005. By 2011, the father-care rate was 19 percent.
Among children in families in poverty in 2011, 18 percent were in center-based care as their primary arrangement, while 11 percent were with other relatives (relatives other than the mother, father, or grandparent). By comparison, more children in families at or above the poverty line were in center-based care (26 percent) than were cared for by other relatives (4 percent).
