RE: Prove this (without using self-selecting statistics).
What do you mean by self-selecting?
Does the study made by an outfit called National Home Education Research Institute for instance, count or not ?
SEE HERE :
If not, what study will satisfy?
“If not, what study will satisfy?”
You made the claim. Prove it. I’m all for Home Schooling, but the statistics that are associated with its superiority over other educational venues are self-selecting, in that they do not compare like statistical pools.
If you have something else, I’d like to see it, otherwise your claim is unsupported.
Bear in mind that we homeschooled our son through HS, and my daughter until HS. Real world experience taught me that homeschooled kids weren’t the rocket scientists portrayed by the homeschooling industry. So I’m extremely skeptical of any study made by the industry.
Now some real world evidence like X% of MIT admissions were homeschooled, that would be real evidence. A study by a home education foundation, not so much.
