Check out AZVA www.k12.com/azva
I have two kids going through this program.. It is an online homeschool charter. My Son recently took the ACT test and scored a 28. He is 13 and starting 8th grade in the fall. We owe most of his success to the AZVA program. They send you all the books and even show you how to coach your children through the lessons. Plus the teachers are there to help online.. We think this type of online school is the future for our children who do not and should not be in brick and mortar schools
