A lot of people don’t have the financial means to send their kids to a private school. Christian or not. Not everyone is able to just quit their job or jobs to teach their kids and most don’t have the ability to pass a state test and deal with all the other obstacles that are put in their way.
It’s called making sacrifices, and, finding a way to make it happen. Joining with others in your area, etc.
This article is about homeschooling, not private school, btw.
“Not everyone is able to just quit their job or jobs”
When I homeschooled my child (K-12, accepted into our state’s prestigious university) I worked in the evenings and weekends. Homeschooling doesn’t take as long as traditional school because you aren’t transitioning 30 kids many times a day, etc.
There were many parents I knew who worked from home or had other non-traditional jobs so that they could home school. It’s doable if you get creative. And SO rewarding.
