This "study" you posted does not really hold much water.
First off it is eleven years old.
Second it was commissioned by by a home schooling organization and done by the president of another home schooling group. This is the equivalent of the DNC commissioning Debbie Wasserman Schultz to poll its members to see who would make a better candidate, Romney or Obama.
Third while the same size is a good representation it is skewed. They sampled 7000 students 5000 of which had been home schooled for 7 years or more. That means that Sixty six percent of the sample were home schooled.
These two sites say that the percent of students being home schooled is somewhere between 3-4%.

The second site says that there are a number of people that they were not able to get information on and estimates that the actual number is higher. even if you say it is double (8%) the sample is still skewed.
Finally I asked for STUDIES plural.
One would think that you would have dozens at your finger tips.
Two comments on studies: Effectiveness of government schooling and homeschooling
1) Where are the studies that **prove** government schools teach anything? Honestly, this is a serious question.
It is my anecdotal observation that academically successful institutionalized children are doing **everything** that successful homeschoolers are doing. And....These successful institutionalized children are spending about the same amount of time doing homework as homeschoolers spend in formal study.
So?....Where are the studies that separate out what is learned due to the afterschooling and homework done by the parents, child, and paid and unpaid tutors as compared to that knowledge acquired in the classroom?
I have posted this question many times on Free Republic and other sites, and personally e-mailed education professors in leading universities. Answer: These studies have **never** been done.
Conclusion: Taxpayers spend up to $30,000/year/child and NO ONE KNOWS if government schools are effective. They may even be retarding educational progress. Unbelievable!
2) As for homeschooling studies, then we should ask government teachers or college level professors of education. It is **THEIR** profession. If they were truly curious people and sincerely interested in the education of children, they would have thoroughly studied the effectiveness or ineffectiveness of homeschooling by now.
If you are a teacher, there should be **dozens** of studies at** your** finger tips. Where are they?
