Record: David Sikkink and Sara Skiles, “Homeschooling and Young Adult Outcomes: Evidence from the 2011 and 2014 Cardus Education Survey” (2015): 1-16. [Available Here]
Summary: Cardus Religious Schools Initiative released their first survey in 2011 (review available here). They later released their second study in 2014 (review available here). These studies provide rare randomly sampled data about young adults who had been homeschooled in the United States. In this article David Sikkink and Sara Skiles analyze data from both studies to draw conclusions about the outcomes of homeschoolers in areas like the development of moral and religious values, family relationships, educational outcomes, and civic life.
A second, fully revised edition of my 2008 book Homeschool: An American History, was published in March of 2017.
