If Kim really understood her shortcomings as a homeschool educator, she would be putting extra effort in the younger girl's homeschool education. If she now realizes she wasn't teaching the younger kids, she should enroll the younger ones in school. Surely there is a private Christian school that would align with her values. Now that Ethan has brought up how he felt about only being allowed to date who you are going to marry, why doesn't Kim talk with the other children and allow them to date or even have friends. It's not too late for the younger girls and even Isaac. Isaac is 16, he has 2 where he can learn a lot and be prepared for college/trade school. If she really realized her wrong doings in how she raised the kids, she'd be making changes to help the other children at home.
