"Dr. Thomas Smedley believes that homeschoolers have superior socialization skills, and his research supports this claim. He conducted a study in which he administered the Vineyard Adaptive Behavior Scales test to identify mature and well-adapted behaviors in children. Home learners ranked in the 84th percentile, compared to publicly schooled students, who were drastically lower in the 23rd."
Sounds impressive, but "Vineyard Adaptive Behavior Scales"? What is that? Google turns up nothing.
