I'm with Jack. The majority of home educators I have met have had what one could politely call 'issues', and their offspring have found it difficult to re-enter the educational mainstream for higher education.
Of course there are exceptions, and I have met some very successful people who have been home-schooled, but the majority seem to emerge as the victims of a half-arsed experiment by their parents. As John says, there needs to be a proper framework to ensure that the kids are being properly educated. And not, as in one case I know, of having 12-year-olds taught history by having them colour in pictures of knights in armour and pick what they want to watch on American K-12 websites.
