I think it is so great that there are options. We discussed them when our daughter was about to enter kindergarten but we were not well informed and thought that it was something we could not do. {we had a 'school' in our garage and would have 'lessons' with her, as well as the other kids prior to entering school}.
When the public school system disappointed me, I turned to homeschooling. I loved it. I didn't 'unschool' but, really, it was as close to it as I could while still meeting the requirements.
I only did it for two years {one per son} but I loved it. A friend of mine homeschooled and she was given everything~computer, internet, supplies {art, science,etc.} but she was required to check in daily via the internet. That sucks.
I liked that I had more control.
I would recommend homeschooling/unschooling to anyone. Anyone who will give the proper time to it, that is. I know someone right now whose son would benefit from the one on one attention but she just refuses to even try it.
