Average score, all students - 20.9
Homeschooled students - 22.5
They are doing pretty well for students whose teachers are, according to you, unqualified to teach anything.
I have been homeschooling my kids since 1986. I have a degree in chemistry. My husband has an MD. Are we among the unqualified?
My son, who had never been to school in his life, scored 27 on his ACT (90th percentile). He graduated from the University of Missouri last May. He was hired by a major food company in a PR capacity and interacts with the public on a regular basis (good socialization skills).
Are we unusual? I don't think so. I base that judgment on the hundreds of homeschoolers we have met in four different states over nearly twenty years of homeschooling.
