All tested above grade level on state mandatory testing throughout their schooling.
Two graduated early (some with college credits).
My adult children (4 sons, ages 19-25) have gainful employment, living on their own (2 own their own homes), and standing on their own. One is married (I got a grandkid!), all have friends, communities they're involved in, and are healthy (physically and mentally).
None take prescription meds nor struggle with anxiety or depression.
Poor public school kids... I hope they can find help for the damage they suffered. <grin>
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>
God says children are a blessing and I know it to be true. I'm grateful for all the children he gave me (7).
Protestant Christian and most of my Christian brothers and sisters look at how many kids I have and that we homeschool and think I'm a little crazy (just like most non-Christians). I'd say probably 1/3 of the families in our church homeschool though. It's a wonderful community to be a part of and if I sent my remaining kids to public school, I wouldn't be asked to leave.
I've been around Mormons, not a religion scholar, but it seems plausible to me the same "one upsmanship" mormons have with missions, large paternalistic families, avoiding "outsiders" (see: homeschooling), etc are common in other religious communities. Like maybe the protestant Christian one you are in?
Wow that's a lot, how did you manage?
(My wife and I have had 9.)
I've been working from home for nearly 2 decades and have flexible hours.
My wife handles the majority of the grade school years (basic reading/writing/maths) and I teach most of the middle and high school.
They've always been involved in co-ops, church activities, and get plenty of socialization. They're emotionally mature, civically responsible, and others focused. We take them when we volunteer at local non-profits, whether that's sorting clothes at the local thrift store or picking up trash at a local park. An example of service becomes a lifestyle of generosity. It makes for great kids and even greater adults.
Put the time and work in to your kids. Nothing else will provide greater dividends.
