New research shows that more Americans are homeschooling their children, and it’s not just conservative Christians.

The number of children who are homeschooled has risen 74 percent since the Department of Education started tracking the numbers in 1999. As of 2007, 2.9 percent of school-age children are homeschooled, 1.5 million children.

Parents are turning to homeschooling less for moral or religious reasons than before, according to the research. One researcher described a growing group of parents who are rejecting education standardization and embracing nontraditional education for their children – what they call “unschooling.”

The “unschooling” group is viewed by educators as a subset of home-schoolers, who generally follow standard curriculum and grading systems. “Unschoolers” create their own systems.

Are parents rejecting traditional education standards or does this reflect an increasingly private view of the family, I wonder?
