I think home schooling is a great option for parents who have the time, and want their children to really excel. In my opinion there is just to many breaks and wasted time in the classrooms. For example, way to many holiday breaks, statutory holidays, professional days. I think a great profession for children is to become teachers.... Lots of days off with too much pay...
Veteran homeschoolers of 17 years. School is certainly not for everyone.
I think your survey should include, "Have you home schooled your kids". My children are now 23 and 25 and I answered yes to the first question.
