My dd is not a big fan of schooling.Currently Montessori. I think she would really dislike online schooling for upper grades. I know she disliked public school.
I have suggested she homeschool when the time is right,learn what interests her,and take the GED test at the earliest age.In Ohio it is 16 if approval is given by parents and the district super.
I see no reason why she needs to stay in *school* till 18,or go to public high school when her Montessori school ends at grade 8. I think the GED should be acceptable for my dh,and it is something accepted for getting into local colleges when she would want to do that(if she does).
What have your teens done when they were 16-18?
