This article discusses a survey done for HSDLA which involved 7,306 adults who were homeschooled. People worry about socialization for homeschoolers. According to this survey, that's not a big deal. Homeschooled adults are involved in community service at a rate of 71% as opposed to the 37% for the general population. Of those who are 18-24 14% worked for a candidate or cause as opposed to 1% of the general population. Of those who are 25-39 13% worked for a candidate or cause as opposed to 5% of the general population. Of the younger group, 75% have voted in the last 5 years, while only 29% of the general population that age voted. Of the older group, 95% voted in the last 5 years, while only 40% of the general population did.
This study from 1999 said, “Major findings include: the achievement test scores of this group of home school students are exceptionally high–the median scores were typically in the 70th to 80th percentile; 25% of home school students are enrolled one or more grades above their age-level public and private school peers….” So the homeschooled child isn't missing out academically either.
Of course, these weren't the first homeschool adults ever studied. This site covers a study from 1994 that says that homeschooled adults are not disadvantaged socially.
It's interesting. I've been homeschooling for eight years. My children are one at least one full grade above their public school counterparts. Their achievement test scores are remarkably high. But they're just kids. They aren't finished growing yet. Of course, neither have I and I'm a lot older than they are.
