None chose to go to college so far. The kind of work they wanted to do didn't require it so they didn't. If they had wanted to be medical doctors, lawyers, or some kind of physical engineer, I'm sure they could have gotten into a good college and found a good job for that.
One is a commercial sheet metal worker and owns his own home.
Another is a Linux sysadmin and owns his own home and has a spouse and a child.
Another is a restaurant equipment repairman and rents.
Finally, my 19 year old just started his airplane mechanic apprenticeship and rents.
My other three are still in school and living in our family home.
The thought at you need college degree to find meaningful employment or to live a joyful life is simply false so I don't consider it a metric for homeschooling success.
I teach my kids how to learn and encourage them to get out there and be productive doing work they enjoy and raising their own families.
Success in my book means they can function as an adult, stand on their own financially, find a good spouse, and bring me some awesome grandkids to spoil.
I don't have a college degree but I make plenty to raise 7 kids while working from home. I got to be there for all their first steps and struggles through Algebra 2 and everything in between. I wouldn't trade working from home and homeschooling for anything. It's been very fulfilling.
Now where's my grandkids! <grin>
